Balloon Occlusion: Use of a balloon CATHETER to block the flow of blood through an artery or vein.Catheterization: Use or insertion of a tubular device into a duct, blood vessel, hollow organ, or body cavity for injecting or withdrawing fluids for diagnostic or therapeutic purposes. It differs from INTUBATION in that the tube here is used to restore or maintain patency in obstructions.Angioplasty, Balloon: Use of a balloon catheter for dilation of an occluded artery. It is used in treatment of arterial occlusive diseases, including renal artery stenosis and arterial occlusions in the leg. For the specific technique of BALLOON DILATION in coronary arteries, ANGIOPLASTY, BALLOON, CORONARY is available.Embolization, Therapeutic: A method of hemostasis utilizing various agents such as Gelfoam, silastic, metal, glass, or plastic pellets, autologous clot, fat, and muscle as emboli. It has been used in the treatment of spinal cord and INTRACRANIAL ARTERIOVENOUS MALFORMATIONS, renal arteriovenous fistulas, gastrointestinal bleeding, epistaxis, hypersplenism, certain highly vascular tumors, traumatic rupture of blood vessels, and control of operative hemorrhage.Carotid Artery, Internal: Branch of the common carotid artery which supplies the anterior part of the brain, the eye and its appendages, the forehead and nose.Collateral Circulation: Maintenance of blood flow to an organ despite obstruction of a principal vessel. Blood flow is maintained through small vessels.Angioplasty, Balloon, Coronary: Dilation of an occluded coronary artery (or arteries) by means of a balloon catheter to restore myocardial blood supply.Cavernous Sinus: An irregularly shaped venous space in the dura mater at either side of the sphenoid bone.Superior Sagittal Sinus: The long large endothelium-lined venous channel on the top outer surface of the brain. It receives blood from a vein in the nasal cavity, runs backwards, and gradually increases in size as blood drains from veins of the brain and the DURA MATER. Near the lower back of the CRANIUM, the superior sagittal sinus deviates to one side (usually the right) and continues on as one of the TRANSVERSE SINUSES.Carotid Artery Diseases: Pathological conditions involving the CAROTID ARTERIES, including the common, internal, and external carotid arteries. ATHEROSCLEROSIS and TRAUMA are relatively frequent causes of carotid artery pathology.Intracranial Aneurysm: Abnormal outpouching in the wall of intracranial blood vessels. Most common are the saccular (berry) aneurysms located at branch points in CIRCLE OF WILLIS at the base of the brain. Vessel rupture results in SUBARACHNOID HEMORRHAGE or INTRACRANIAL HEMORRHAGES. Giant aneurysms (>2.5 cm in diameter) may compress adjacent structures, including the OCULOMOTOR NERVE. (From Adams et al., Principles of Neurology, 6th ed, p841)Intra-Aortic Balloon Pumping: Counterpulsation in which a pumping unit synchronized with the patient's electrocardiogram rapidly fills a balloon in the aorta with helium or carbon dioxide in early diastole and evacuates the balloon at the onset of systole. As the balloon inflates, it raises aortic diastolic pressure, and as it deflates, it lowers aortic systolic pressure. The result is a decrease in left ventricular work and increased myocardial and peripheral perfusion.Stents: Devices that provide support for tubular structures that are being anastomosed or for body cavities during skin grafting.Treatment Outcome: Evaluation undertaken to assess the results or consequences of management and procedures used in combating disease in order to determine the efficacy, effectiveness, safety, and practicability of these interventions in individual cases or series.Intraoperative Care: Patient care procedures performed during the operation that are ancillary to the actual surgery.

These compounds are often used as radionuclide imaging agents.Technetium Tc 99m Exametazime: A gamma-emitting RADIONUCLIDE IMAGING agent used in the evaluation of regional cerebral blood flow and in non-invasive dynamic biodistribution studies and MYOCARDIAL PERFUSION IMAGING. It has also been used to label leukocytes in the investigation of INFLAMMATORY BOWEL DISEASES.Coronary Occlusion: Complete blockage of blood flow through one of the CORONARY ARTERIES, usually from CORONARY ATHEROSCLEROSIS.Intracranial Embolism: Blocking of a blood vessel in the SKULL by an EMBOLUS which can be a blood clot (THROMBUS) or other undissolved material in the blood stream. Most emboli are of cardiac origin and are associated with HEART DISEASES. Other non-cardiac sources of emboli are usually associated with VASCULAR DISEASES.Myocardial Stunning: Prolonged dysfunction of the myocardium after a brief episode of severe ischemia, with gradual return of contractile activity.Myocardial Ischemia: A disorder of cardiac function caused by insufficient blood flow to the muscle tissue of the heart. The decreased blood flow may be due to narrowing of the coronary arteries (CORONARY ARTERY DISEASE), to obstruction by a thrombus (CORONARY THROMBOSIS), or less commonly, to diffuse narrowing of arterioles and other small vessels within the heart. Severe interruption of the blood supply to the myocardial tissue may result in necrosis of cardiac muscle (MYOCARDIAL INFARCTION).Swine: Any of various animals that constitute the family Suidae and comprise stout-bodied, short-legged omnivorous mammals with thick skin, usually covered with coarse bristles, a rather long mobile snout, and small tail. Included are the genera Babyrousa, Phacochoerus (wart hogs), and Sus, the latter containing the domestic pig (see SUS SCROFA).Time Factors: Elements of limited time intervals, contributing to particular results or situations.Coronary Vessels: The veins and arteries of the HEART.Retinal Vein Occlusion: Blockage of the RETINAL VEIN. Those at high risk for this condition include patients with HYPERTENSION; DIABETES MELLITUS; ATHEROSCLEROSIS; and other CARDIOVASCULAR DISEASES.Arteriovenous Fistula: An abnormal direct communication between an artery and a vein without passing through the CAPILLARIES. An A-V fistula usually leads to the formation of a dilated sac-like connection, arteriovenous aneurysm. The locations and size of the shunts determine the degree of effects on the cardiovascular functions such as BLOOD PRESSURE and HEART RATE.Coronary Angiography: Radiography of the vascular system of the heart muscle after injection of a contrast medium.Arterial Occlusive Diseases: Pathological processes which result in the partial or complete obstruction of ARTERIES. They are characterized by greatly reduced or absence of blood flow through these vessels.

They may or may not be associated with the disease for which the surgery is done, or within the same surgical procedure.Cardiac Catheterization: Procedures in which placement of CARDIAC CATHETERS is performed for therapeutic or diagnostic procedures.Tomography, Emission-Computed, Single-Photon: A method of computed tomography that uses radionuclides which emit a single photon of a given energy. The camera is rotated 180 or 360 degrees around the patient to capture images at multiple positions along the arc. The computer is then used to reconstruct the transaxial, sagittal, and coronal images from the 3-dimensional distribution of radionuclides in the organ. The advantages of SPECT are that it can be used to observe biochemical and physiological processes as well as size and volume of the organ. The disadvantage is that, unlike positron-emission tomography where the positron-electron annihilation results in the emission of 2 photons at 180 degrees from each other, SPECT requires physical collimation to line up the photons, which results in the loss of many available photons and hence degrades the image.Vena Cava, Inferior: The venous trunk which receives blood from the lower extremities and from the pelvic and abdominal organs.Follow-Up Studies: Studies in which individuals or populations are followed to assess the outcome of exposures, procedures, or effects of a characteristic, e.g., occurrence of disease.Dogs: The domestic dog, Canis familiaris, comprising about 400 breeds, of the carnivore family CANIDAE.

(Walker's Mammals of the World, 5th ed, p1065)Disease Models, Animal: Naturally occurring or experimentally induced animal diseases with pathological processes sufficiently similar to those of human diseases. They are used as study models for human diseases.Coronary Disease: An imbalance between myocardial functional requirements and the capacity of the CORONARY VESSELS to supply sufficient blood flow. It is a form of MYOCARDIAL ISCHEMIA (insufficient blood supply to the heart muscle) caused by a decreased capacity of the coronary vessels.Electrocardiography: Recording of the moment-to-moment electromotive forces of the HEART as projected onto various sites on the body's surface, delineated as a scalar function of time. The recording is monitored by a tracing on slow moving chart paper or by observing it on a cardioscope, which is a CATHODE RAY TUBE DISPLAY.Myocardial Infarction: NECROSIS of the MYOCARDIUM caused by an obstruction of the blood supply to the heart (CORONARY CIRCULATION).Myocardial Reperfusion: Generally, restoration of blood supply to heart tissue which is ischemic due to decrease in normal blood supply. The decrease may result from any source including atherosclerotic obstruction, narrowing of the artery, or surgical clamping. Reperfusion can be induced to treat ischemia. Methods include chemical dissolution of an occluding thrombus, administration of vasodilator drugs, angioplasty, catheterization, and artery bypass graft surgery. However, it is thought that reperfusion can itself further damage the ischemic tissue, causing MYOCARDIAL REPERFUSION INJURY.Neurologic Examination: Assessment of sensory and motor responses and reflexes that is used to determine impairment of the nervous system.Blood Flow Velocity: A value equal to the total volume flow divided by the cross-sectional area of the vascular bed.Balloon Valvuloplasty: Widening of a stenosed HEART VALVE by the insertion of a balloon CATHETER into the valve and inflation of the balloon.Carotid Stenosis: Narrowing or stricture of any part of the CAROTID ARTERIES, most often due to atherosclerotic plaque formation. Ulcerations may form in atherosclerotic plaques and induce THROMBUS formation. Platelet or cholesterol emboli may arise from stenotic carotid lesions and induce a TRANSIENT ISCHEMIC ATTACK; CEREBROVASCULAR ACCIDENT; or temporary blindness (AMAUROSIS FUGAX). (From Adams et al., Principles of Neurology, 6th ed, pp 822-3)Dental Occlusion: The relationship of all the components of the masticatory system in normal function. It has special reference to the position and contact of the maxillary and mandibular teeth for the highest efficiency during the excursive movements of the jaw that are essential for mastication. (From Jablonski, Dictionary of Dentistry, 1992, p556, p472)Tomography, X-Ray Computed: Tomography using x-ray transmission and a computer algorithm to reconstruct the image.Ventricular Function, Left: The hemodynamic and electrophysiological action of the left HEART VENTRICLE. Its measurement is an important aspect of the clinical evaluation of patients with heart disease to determine the effects of the disease on cardiac performance.Blood Pressure: PRESSURE of the BLOOD on the ARTERIES and other BLOOD VESSELS.Contrast Media: Substances used to allow enhanced visualization of tissues.Preoperative Care: Care given during the period prior to undergoing surgery when psychological and physical preparations are made according to the special needs of the individual patient. This period spans the time between admission to the hospital to the time the surgery begins. (From Dictionary of Health Services Management, 2d ed)Angioplasty, Balloon, Laser-Assisted: Techniques using laser energy in combination with a balloon catheter to perform angioplasty. These procedures can take several forms including: 1, laser fiber delivering the energy while the inflated balloon centers the fiber and occludes the blood flow; 2, balloon angioplasty immediately following laser angioplasty; or 3, laser energy transmitted through angioplasty balloons that contain an internal fiber.Prospective Studies: Observation of a population for a sufficient number of persons over a sufficient number of years to generate incidence or mortality rates subsequent to the selection of the study group.Constriction, Pathologic: The condition of an anatomical structure's being constricted beyond normal dimensions.Graft Occlusion, Vascular: Obstruction of flow in biological or prosthetic vascular grafts.Infarction, Middle Cerebral Artery: NECROSIS occurring in the MIDDLE CEREBRAL ARTERY distribution system which brings blood to the entire lateral aspects of each CEREBRAL HEMISPHERE. Clinical signs include impaired cognition; APHASIA; AGRAPHIA; weak and numbness in the face and arms, contralaterally or bilaterally depending on the infarction.Brain Ischemia: Localized reduction of blood flow to brain tissue due to arterial obstruction or systemic hypoperfusion. This frequently occurs in conjunction with brain hypoxia (HYPOXIA, BRAIN). Prolonged ischemia is associated with BRAIN INFARCTION.Carotid Artery Injuries: Damages to the CAROTID ARTERIES caused either by blunt force or penetrating trauma, such as CRANIOCEREBRAL TRAUMA; THORACIC INJURIES; and NECK INJURIES. Damaged carotid arteries can lead to CAROTID ARTERY THROMBOSIS; CAROTID-CAVERNOUS SINUS FISTULA; pseudoaneurysm formation; and INTERNAL CAROTID ARTERY DISSECTION. (From Am J Forensic Med Pathol 1997, 18:251; J Trauma 1994, 37:473)Iliac Artery: Either of two large arteries originating from the abdominal aorta; they supply blood to the pelvis, abdominal wall and legs.Pulmonary Valve Stenosis: The pathologic narrowing of the orifice of the PULMONARY VALVE. This lesion restricts blood outflow from the RIGHT VENTRICLE to the PULMONARY ARTERY. When the trileaflet valve is fused into an imperforate membrane, the blockage is complete.Angiography: Radiography of blood vessels after injection of a contrast medium.Femoral Artery: The main artery of the thigh, a continuation of the external iliac artery.Constriction: The act of constricting.Mitral Valve Stenosis: Narrowing of the passage through the MITRAL VALVE due to FIBROSIS, and CALCINOSIS in the leaflets and chordal areas. This elevates the left atrial pressure which, in turn, raises pulmonary venous and capillary pressure leading to bouts of DYSPNEA and TACHYCARDIA during physical exertion. RHEUMATIC FEVER is its primary cause.Tunica Intima: The innermost layer of an artery or vein, made up of one layer of endothelial cells and supported by an internal elastic lamina.Mesenteric Vascular Occlusion: Obstruction of the flow in the SPLANCHNIC CIRCULATION by ATHEROSCLEROSIS; EMBOLISM; THROMBOSIS; STENOSIS; TRAUMA; and compression or intrinsic pressure from adjacent tumors.

Percutaneous mitral valvotomy in patients eighteen years old and younger. Immediate and late results. (1/336)

OBJECTIVE - To analyze immediate and late results of percutaneous mitral valvotomy (PMV) in patients < or = 18 year. METHODS - Between August '87 and July '97, 48 procedures were performed on 40 patients. The mean age was 15.6 years; 68.7% were females four of whom were pregnant. RESULTS - Success was obtained in 91.7% of the procedures. Immediate complications were severe mitral regurgitation (6.3%) and cardiac tamponade (2.0%). Late follow-up was obtained in 88.8% of the patients (mean value=43.2+/-33.9 months). NYHA functional class (FC) I or II was observed in 96.2% of the patients and restenosis developed in five patients, at a mean follow-up of 29.7+/-11.9 months. Three patients presented with severe mitral insufficiency and underwent surgery. Two patients died. CONCLUSION - PMV represents a valid therapeutic option in young patients. In these patients, maybe because of subclinical rheumatic activity, restenosis may have a higher incidence and occur at an earlier stage than in others persons.  (+info)

Subclavian artery disruption resulting from endovascular intervention: treatment options. (2/336)

Endovascular intervention is a commonly accepted form of treatment in patients with subclavian artery stenosis. Complications will undoubtedly occur as the utility of catheter-based intervention continues to rise. We report two cases of subclavian artery disruption as a result of endovascular intervention. One patient had contrast extravasation after the deployment of a balloon-expandable stent in a stenotic subclavian artery, and the arterial injury was successfully treated with balloon tamponade. A second patient had a large subclavian pseudoaneurysm 4 months after a balloon-expandable stent placement. Successful repair was achieved in this patient by means of arterial reconstruction with a prosthetic bypass graft. These cases illustrate different therapeutic methods of treating subclavian artery rupture due to endovascular intervention.  (+info)

Endovascular grafts and other image-guided catheter-based adjuncts to improve the treatment of ruptured aortoiliac aneurysms. (3/336)

OBJECTIVE: To report a new management approach for the treatment of ruptured aortoiliac aneurysms. METHODS: This approach includes hypotensive hemostasis, minimizing fluid resuscitation, and allowing the systolic blood pressure to fall to 50 mmHg. Under local anesthesia, a transbrachial guidewire was placed under fluoroscopic control in the supraceliac aorta. A 40-mm balloon catheter was inserted over this guidewire and inflated only if the blood pressure was less than 50 mmHg, before or after the induction of anesthesia. Fluoroscopic angiography was used to determine the suitability for endovascular graft repair. When possible, a prepared, "one-size-fits-most" endovascular aortounifemoral stented PTFE graft was used, combined with occlusion of the contralateral common iliac artery and femorofemoral bypass. If the patient's anatomy was unsuitable for endovascular graft repair, standard open repair was performed using proximal balloon control as needed. RESULTS: Twenty-five patients with ruptured aortoiliac aneurysms (18 aortic, 7 iliac) were managed using this approach. Balloon inflation for proximal control was required in nine of the 25 patients. Twenty patients were treated with endovascular grafts. Five patients required open repair. The ruptured aneurysm was excluded in all 25 patients; 23 survived. Two deaths occurred in patients who received endovascular grafts with serious comorbidities. The surviving patients who received endovascular grafts had a median hospital stay of 6 days, and the preoperative symptoms resolved in all patients. CONCLUSIONS: Hypotensive hemostasis is usually an effective means to provide time for balloon placement and often for endovascular graft insertion. With appropriate preparation and planning, many if not most patients with ruptured aneurysms can be treated by endovascular grafts. Proximal balloon control is not required often but may, when needed, be an invaluable adjunct to both endovascular graft and open repairs. The use of endovascular grafts and this approach using other image-guided catheter-based adjuncts appear to improve treatment outcomes for patients with ruptured aortoiliac aneurysms.  (+info)

Methods for assessing hepatic distending pressure and changes in hepatic capacitance in pigs. (4/336)

The equilibrium pressure obtained during simultaneous occlusion of hepatic vascular inflow and outflow was taken as the reference estimate of hepatic vascular distending pressure (P(hd)). P(hd) at baseline was 1.1 +/- 0.2 (mean +/- SE) mmHg higher than hepatic vein pressure (P(hv)) and 0.7 +/- 0.3 mmHg lower than portal vein pressure (P(pv)). Norepinephrine (NE) infusion increased P(hd) by 1. 5 +/- 0.5 mmHg and P(pv) by 3.7 +/- 0.6 mmHg but did not significantly increase P(hv). Hepatic lobar vein pressure (P(hlv)) measured by a micromanometer tipped 2-Fr catheter closely resembled P(hd) both at baseline and during NE-infusion. Dynamic pressure-volume (PV) curves were constructed from continuous measurements of P(hv) and hepatic blood volume increases (estimated by sonomicrometry) during brief occlusions of hepatic vascular outflow and compared with static PV curves constructed from P(hd) determinations at five different hepatic volumes. Estimates of hepatic vascular compliance and changes in unstressed blood volume from the two methods were in close agreement with hepatic compliance averaging 32 +/- 2 ml. mmHg(-1). kg liver(-1). NE infusion reduced unstressed blood volume by 110 +/- 38 ml/kg liver but did not alter compliance. In conclusion, P(hlv) reflects hepatic distending pressure, and the construction of dynamic PV curves is a fast and valid method for assessing hepatic compliance and changes in unstressed blood volume.  (+info)

Protein washdown as a defense mechanism against myocardial edema. (5/336)

Myocardial edema occurs in many pathological conditions. We hypothesized that protein washdown at the myocardial microvascular exchange barrier would change the distribution of interstitial proteins from large to small molecules and diminish the effect of washdown on the colloid osmotic pressure (COP) of interstitial fluid and lymph. Dogs were instrumented with coronary sinus balloon-tipped catheters and myocardial lymphatic cannulas to manipulate myocardial lymph flow and to collect lymph. Myocardial venous pressure was elevated by balloon inflation to increase transmicrovascular fluid flux and myocardial lymph flow. COP of lymph was measured directly and was also calculated from protein concentration. Decreases occurred in both protein concentration and COP of lymph. The proportion of lymph protein accounted for by albumin increased significantly, whereas that accounted for by beta-lipoprotein decreased significantly. The change in the calculated plasma-to-lymph COP gradient was significantly greater than the change in the measured COP gradient. We conclude that the change in the distribution of interstitial fluid protein species decreases the effect of protein washdown on interstitial fluid COP and limits its effectiveness as a defense mechanism against myocardial edema formation.  (+info)

Modification of a previously described arteriovenous malformation model in the swine: endovascular and combined surgical/endovascular construction and hemodynamics. (6/336)

BACKGROUND AND PURPOSE: The rete mirabile in swine has been proposed as an arteriovenous malformation (AVM) model for acute experimental studies through surgical creation of a large carotid-jugular fistula. This report describes two endovascular modifications to simplify the surgical creation and provides hemodynamic parameters for the AVM model. METHODS: An AVM model was created in 29 animals to study n-butyl 2-cyanoacrylate polymerization kinetics. The common carotid artery (CCA) was punctured and a guiding catheter was inserted tightly into the origin of the ascending pharyngeal artery (APA). The CCA was ligated proximal to the catheter to create a pressure drop across the rete, which represented the AVM nidus. The catheter hub was opened whenever needed and served as the venous drainage of the AVM nidus. The contralateral APA served as the arterial feeder. Instead of the surgical ligation of the CCA, a temporary balloon occlusion was performed in three animals. RESULTS: A mean pressure gradient of 14.9 +/- 10.5 mm Hg (range, 4-42 mm Hg) was measured across the rete. The mean flow rate was 30.4 +/- 14.2 mL/min (range, 3.5-46 mL/min), as measured at the venous drainage. CONCLUSION: The endovascular and combined surgical-endovascular rete AVM model in swine is easy to construct and is less time-consuming than are the currently used models for acute experimental studies. Hemodynamic parameters can be monitored during the entire experiment and correspond to values found in human cerebral AVMs.  (+info)

Endovascular treatment of experimental aneurysms by use of a combination of liquid embolic agents and protective devices. (7/336)

BACKGROUND AND PURPOSE: The use of liquid embolic agents for embolization of cerebral aneurysms has been reported in the neurosurgical literature. The most important limitation of this technique is the relatively poor control of migration of the liquid embolic agent into the parent artery. We performed an experimental aneurysm study using a liquid embolic agent and different protective devices to evaluate the safety and technical feasibility of this endovascular technique. METHODS: Forty lateral aneurysms were surgically constructed on 20 common carotid arteries of swine. Onyx alone was used to obliterate eight aneurysms. Onyx was also used in combination with microcoils (n = 11), microstents (n = 6), balloons inflated proximally to the neck of the aneurysm (n = 6), and across the neck of the aneurysm (n = 7). One control aneurysm was embolized with Guglielmi detachable coils (GDCs) alone. RESULTS: The use of a microballoon across the neck of the aneurysm, a microstent deployed across the neck of the aneurysm, or the deposit of GDCs into the aneurysm allowed faster and more complete filling of the aneurysm with Onyx. However, these protection devices did not totally preclude intractable migration of Onyx into the parent artery (migration rate, 9-33%). CONCLUSION: Although complete occlusion of experimental aneurysms with Onyx is feasible using protective devices, migration of the liquid embolic agent into the parent artery or intracranially remains a difficult challenge. Further experimental studies need to be performed to master this technique and to select those aneurysms that can be safely treated in clinical practice.  (+info)

Double-balloon technique for embolization of carotid cavernous fistulas. (8/336)

Embolization of a carotid cavernous fistula (CCF) by means of a detachable balloon is an established method for treating CCFs while preserving a patent parent internal carotid artery (ICA). However, failure to embolize the CCF may occur on a few occasions, such as when the balloon cannot pass through the fistula into the cavernous sinus by blood flow, or when the inflated balloon in the cavernous sinus retracts to the carotid artery. Under these circumstances, the ICA may have to be sacrificed in order to treat the CCF. Herein we describe a double-balloon technique for embolization of a CCF. By applying this technique, we successfully treated nine of 11 CCFs, without compromise of the parent ICA when the conventional one-balloon technique failed.  (+info)

It is unknown whether spontaneous gastrorenal shunts actually develop in the pediatric population. The minimum age documented in studies from Asia is 32 (range 32-44) years. This study describes three pediatric patients undergoing balloon-occluded retrograde transvenous obliteration (BRTO) for bleeding gastric varices with two of the three patients undergoing combined partial splenic embolization. The first BRTO is a selective-BRTO via a surgical splenorenal shunt (15 years old) and the other two patients underwent conventional-BRTO via a spontaneous gastrorenal shunt (8 and 14 years old). The recurrent significant bleeding that they exhibited before the combined endovascular therapy did not recur for an average of 7.1 (range 1.4-14) months. In the second patient, quantitative digitally subtracted angiography was utilized to evaluate the inline portal venous flow before and after BRTO. ...
Approximately one in six patients with portal hypertension who develop varices at sites of portosystemic venous collaterals has gastric varices due to hepatofugal flow into the gastric veins. Bleeding from gastric varices, though less common, has a higher mortality and morbidity compared to bleeding esophageal varices, which are easier to manage endoscopically. The efferent channel for gastric varices is mostly the gastrorenal shunt (GRS) which opens into the left renal vein. Balloon-occluded transvenous obliteration (BRTO) involves accessing the GRS with an aim to temporarily occlude its outflow using a balloon catheter and at the same time injecting sclerosant mixture within the varix so as to cause its thrombosis and thereby obliteration ...
An intravascular occlusion balloon catheter having a removable hub, a profile sized to approximate a guidewire, and a means for venting air from the balloon. The removable hub and the small profile allow the occlusion balloon catheter to be used as a guidewire. The venting means allows air to be easily and reliably removed from the balloon prior to use.
This retrospective review of patients medical and imaging records was approved by each institutional review board. A total of 183 patients with liver cirrhosis (LC) who underwent BRTO for the treatment of endoscopically confirmed GV bleeding at Kyungpook National University Hospital, Konkuk University Hospital, Soonchunhyang University Bucheon Hospital, Samsung Medical Center, Kangbook Samsung Hospital, and Hanyang University Guri Hospital, in Korea, between January 2001 and December 2010, were enrolled in this study. No enrolled patients received other endoscopic, surgical or radiologic interventional treatments prior to BRTO. In each patient, GV were confirmed by esophagogastroduodenoscopy (EGD), and gastrorenal shunt was demonstrated by contrast-enhanced computer tomography (CT). GV were classified by anatomic distribution as proposed by Sarin et al.1,18 The sizes of GV were classified according to the system suggested by Hashizume et al19 as follows: grade 0, non visible; grade I, small ...
Objectives: Gastric varices primarily occur in cirrhotic patients with portal hypertension and splenomegaly and thus are probably associated with thrombocytopenia. However, the prevalence and severity of thrombocytopenia are unknown in this clinical setting. Moreover, one-third of patients after balloon-occluded retrograde transvenous obliteration (BRTO) have aggravated splenomegaly, which potentially may cause worsening thrombocytopenia. The aim of the study is to determine the prevalence and degree of thrombocytopenia in patients with gastric varices associated with gastrorenal shunts undergoing BRTO, to determine the prognostic factors of survival after BRTO (platelet count included), and to assess the effect of BRTO on platelet count over a 1-year period. Materials and Methods: This is a retrospective review of 35 patients who underwent BRTO (March 2008-August 2011). Pre- and post-BRTO platelet counts were noted. Potential predictors of bleeding and survival (age, gender, liver disease etiology,

Acute myocardial infarction occurs after SVG stenting in 15% to 28% of cases,13,21-23 often preceded by reduced intraprocedure flow despite adequate mechanical treatment of stenoses (no-reflow). Late morbidity and mortality are higher in patients who have a myocardial infarction after SVG stenting than in those who do not.24 Etiologic possibilities include soluble mediators released from red blood cells, platelets, or leukocytes during stenting, acutely dislodged plaque elements, and delayed embolization of plaque or thrombotic elements. Pharmacological strategies proposed to prevent or treat periprocedural no-reflow have included calcium channel blockers, nitrates, adenosine, thrombolytics, and antiplatelet agents. A registry reported from Brigham and Womens hospital25 demonstrated that despite improving angiographic flow, antiplatelet and vasodilatory agents were not associated with improved clinical outcomes. Mechanical strategies proposed to prevent no-reflow have included direct stenting ...
It is interesting that the presence of border zone shift did not correlate with increased OEF in the cortical regions of the MCA territory. In fact, border zone shift was observed in many patients with normal cerebral hemodynamics (stage 0) in the MCA territory (data not shown). Whether these patients have selective hemodynamic impairment in the arterial border zone remains an unanswered question. If one considers retrograde filling of MCA vessels to the level of the insula as the far end of the spectrum of border zone shift (defined in this study as pial collateralization), then an association with hemodynamic impairment was observed.. These data suggest that delayed venous phase may be an indicator of hemodynamic impairment. This deserves further investigation. The angiographic identification of delayed venous phase in the context of temporary balloon occlusion of the carotid artery has been advocated as an indicator of hemodynamic compromise.45 However, the assessment of delayed venous phase ...
Occlusion balloon catheters of 5.2- or 6-French have been used for a few decades in various endovascular treatments of body trunk vascular lesions. However, these catheters may be difficult to place in cases of excessive vessel tortuosity, small vessels, and anatomic complexity. Recently, the introduction of the double lumen microballoon catheters for body trunk vascular lesions has allowed operators to advance them into more distal, smaller, and more tortuous vessels. Since the launch of the first generation microballoon catheters onto the market in Japan in 2011, the microballoon catheters have evolved and are now generally available for clinical use ...

Emergency endovascular aneurysm repair (eEVAR) for ruptured abdominal aortic aneurysm (rAAA) must be carried out instantly. This requires firm logistics that include the ability to cross-clamp the aorta without delay. The present article focuses on the technique of balloon control of the aorta in eEVAR with aspects on indications as well as the organization of this type of vascular service. Transfemoral insertion of the occlusion balloon under local anesthesia is advocated and described. The use of dual balloons shortens the time of visceral ischemia without necessitating repeat declamping until the aneurysm has been completely excluded. Staged declamping upon completion is necessary just as in open repair. A "balloon test" is suggested to better identify those high risk patients with a rAAA who may benefit from endovascular rAAA repair.. ...
A method of treatment of congestive heart failure comprises the steps of introducing an aortic occlusion catheter through a patients peripheral artery, the aortic occlusion catheter having an occluding member movable from a collapsed position to an expanded position; positioning the occluding member in the patients ascending aorta; moving the occluding member from the collapsed shape to the expanded shape after the positioning step; introducing cardioplegic fluid into the patients coronary blood vessels to arrest the patients heart; maintaining circulation of oxygenated blood through the patients arterial system; and reshaping an outer wall of the patients heart while the heart is arrested so as to reduce the transverse dimension of the left ventricle. The ascending aorta may be occluded and cardioplegic fluid delivered by means of an occlusion balloon attached to the distal end of an elongated catheter positioned transluminally in the aorta from a femoral, subclavian, or other appropriate

OBJECTIVES: We tested whether the poor ability of pulse pressure variation to predict fluid responsiveness in cases of acute respiratory distress syndrome was related to low lung compliance. We also tested whether the changes in cardiac index induced by passive leg-raising and by an end-expiratory occlusion test were better than pulse pressure variation at predicting fluid responsiveness in acute respiratory distress syndrome patients.. DESIGN: Prospective study.. SETTING: Medical intensive care unit.. PATIENTS: We included 54 patients with circulatory shock (63 ± 13 yrs; Simplified Acute Physiology Score II, 63 ± 24). Twenty-seven patients had acute respiratory distress syndrome (compliance of the respiratory system, 22 ± 3 mL/cm H2O). In nonacute respiratory distress syndrome patients, the compliance of the respiratory system was 45 ± 9 mL/cm H2O.. MEASUREMENTS AND MAIN RESULTS: We measured the response of cardiac index (transpulmonary thermodilution) to fluid administration (500 mL ...
The resuscitative endovascular balloon occlusion of the aorta, because of its efficacy and feasibility, has been widely used in treating patients with severe torso trauma. However, complications developing around the site proximal to the occlusion by resuscitative endovascular balloon occlusion of the aorta have almost never been studied. A 50-year-old Japanese woman fell from a height of approximately 10 m. At initial arrival, her respiratory rate was 24 breaths/minute, her blood oxygen saturation was 95% under 10 L/minute oxygenation, her pulse rate was 90 beats per minute, and her blood pressure was 180/120 mmHg. Mild lung contusion, hemopneumothorax, unstable pelvic fracture, and retroperitoneal bleeding with extravasation of contrast media were observed in initial computed tomography. As her vital signs had deteriorated during computed tomography, a 7-French aortic occlusion catheter (RESCUE BALLOON®, Tokai Medical Products, Aichi, Japan) was inserted and inflated for aortic occlusion at the first

Despite its guidewire-like profile, the OCT ImageWire (Lightlab TD-OCT) is not designed to be advanced into the coronary artery as a stand-alone device. Rather, the imagewire is inserted using an over-the-wire balloon catheter (Helios). The Helios balloon has a maximum external diameter of 1.5 mm and is compatible with large 6-F guiding catheters (0.071-inch inner diameter). It is advanced distally to the segment of interest over a conventional angioplasty guidewire (0.014-inch). The guidewire is then exchanged with the OCT ImageWire, and the occlusion balloon is pulled back and repositioned in a healthy proximal segment. The balloon is highly compliant and is inflated at minimal pressure that allows totally clean imaging from blood, usually between 0.4 to 0.7 atm with a dedicated inflator. A contrast injector pump with a warming cuff is set at 0.5 cc/s infusion, which can be increased to up to 1.0 cc/s until blood is completely cleared. The solution is injected through the end-hole distal port ...

A 12 year old boy underwent percutaneous closure of a secundum atrial septal defect under general anaesthetic. He had been pretreated with aspirin and had 100 U/kg of heparin at the start of the procedure. A transoesophageal echocardiogram (TOE) showed acceptable margins and closure was attempted with a 16 mm Amplatzer atrial septal occluder (AGA Medical Corporation, Golden Valley, Minnesota, USA). The device position was unstable because of a floppy posterior margin and the device was retrieved. Successful closure was achieved with a 20 mm device although retrieval and repositioning were required on five occasions.. After release of the device a pedunculated 8 mm thrombus attached to the centre of the left sided disk was seen on TOE (video 1) (to view video footage visit the Heart website-http://www.heartjnl.com/supplemental). There was particular concern about embolisation given the highly mobile appearance of the clot. Treatment with abciximab according to the adult guidelines (bolus of 0.25 ...

Transcatheter PDA closure is now a well-established procedure, that is, performed frequently (1-6), with conventional surgery generally reserved for patients with a large duct or symptomatic preterm infants. A number of devices and techniques have been in clinical use with varying degree of popularity and success since Porstmann et al. (12)introduced the Ivalon plug nearly three decades ago. The extensively investigated Rashkind PDA occluder was once widely accepted, but its high cost, the need for a relatively large transvenous sheath, a late incidence of residual shunt of up to 15% to 20% and the risk of stenosis at the origin of the LPA with the use of the 17 mm device led to the search for alternatives (13). Ironically, the Gianturco coils, though not purpose-designed for closure of PDA, are currently among the most widely used techniques due to its low cost, ease of delivery using small 4F and 5F conventional catheters and, more importantly, its high closure rate, approaching 98% to 100% at ...

A method of manufacturing a folding balloon catheter for use as an angioplasty device, wherein the balloon catheter has atherotomes (21) attached to the exterior of the balloon (12), includes inflating a balloon to its expanded state. A plurality of patches (18) of a curable elastomer adhesive are then applied at selected locations on the outside surface of the inflated balloon, and an atherotome is attached to the balloon at each of the patches. The inflated balloon, with attached atherotomes, is then partially cured to more firmly attach the atherotomes to the balloon. The balloon is then deflated to a contracted configuration in a manner which forms a plurality of flaps (54) in the balloon between the atherotomes. The deflated balloon is then cured to completion to establish a permanent set in the flaps which enable the balloon catheter to be repeatedly inflated and deflated during operation between predictable expanded and contracted configurations.
The present invention provides a balloon having a non-uniform thickness that is adapted to facilitate folding of the balloon. The balloon comprises at least one relatively thin section formed between inner and outer surfaces of the balloon, and at least one relatively thick section formed between the inner and outer surfaces. The balloon may be formed from a balloon preform that similarly comprises at least one relatively thin section and at least one relatively thick section. The shape of the balloon preform may be formed, for example, by extrusion. The balloon preform may be placed in a balloon mold having a substantially cylindrical interior surface, and blow-molded to form the finished balloon configuration. The balloon comprises a non-uniform thickness, while comprising a substantially cylindrical outer diameter both after removal from the balloon mold and in an inflated state.

BACKGROUND: Cardiac output (CO) is a physiological variable that should be monitored during cardiac surgery. The purpose of this study was to assess the trending ability of two CO monitors, esCCO (Nihon Kohden™, Tokyo, Japan) and Volume View (VV) (Edwards Lifesciences, Irvine, USA).. METHODS: A total of 19 patients were included in the study. Before cardiopulmonary bypass (CPB), CO was measured simultaneously using both esCCO and VV devices before and after three CO-modifying manoeuvres (passive leg raise [PLR], the end expiratory occlusion test [EEOT] and positive end expiratory pressure [PEEP] at 10 cm H2O). Five CO values for esCCO and three for VV were averaged and compared during a one-minute period of time before and after each manoeuvre.. RESULTS: A total of 114 paired readings were collected. Median CO values were 4.3 L min-1 (IQR: 3.8; 5.2) and 3.8 L min-1 (IQR: 3.5; 4.5) for esCCO and VV, respectively. The precision error was 1.4% (95% CI:1.0-1.7) for esCCO and 2.2% (95% CI: 1.8-2.7) ...

Market Insights:. The balloon ends of the balloon catheters is very important aspect as it might cause trauma to the vascular endothelial tissues during inflation and hence rounded balloons are preferred more in comparison to other shapes. Two types of balloons are used for surgical procedures, first is the high pressure non elastic balloons and the second is low pressure elastic balloons. These balloons are categorized as non-compliant, semi compliant and high compliant on the basis of the ...
The variable distention angioplasty balloon assembly, for insertion into a blood vessel, comprises an inner elongated, inflatable balloon having a distal portion, a proximal portion and an intermediate portion therebetween and defining therein a first chamber. The inner balloon has a first Youngs modulus. The outer elongated, inflatable balloon has a distal portion, a proximal portion and an intermediate portion therebetween positioned around the inner balloon and defines between the balloons a second chamber. The outer balloon has a second Youngs modulus. The inner balloon is substantially enclosed by the outer balloon, and the first Youngs modulus of the inner balloon is less than the second Youngs modulus of the outer balloon. The first chamber of the inner balloon and the second chamber of the outer balloon define a variable dilation structure for dilating an anatomical stricture. The dilation structure with variable characteristics has a first diameter and pressure characteristic curve defined

A method for forming a balloon for a dilation catheter is provided herein. The method includes the steps of: (i) positioning a tube in a preconditioned mold; (ii) expanding the tube in a preconditioned mold to form a parison; (iii) positioning the parison in a balloon mold; and (iv) expanding the parison within the balloon mold to form the balloon. Thus, the tube is initially expanded into a parison in the preconditioned mold. Subsequently, the parison is expanded into a balloon in the balloon mold. Because of this unique manufacturing process, polyester block copolymers can be formed into balloons. Some of these polyester block copolymers could not be formed into a balloon using prior art blow molding processes. The resulting balloon exhibits superior characteristics, including relatively thin and consistent walls, soft texture, low uninflated crossing profile, expansion in a predictable fashion, and good tensile strength.
A balloon occlusion device for aspirating embolic material from a blood vessel, such as from the aorta during cardiac surgery. The device includes an arterial cannula having a proximal end adapted to receive blood from a bypass-oxygenator machine, a distal end adapted to enter an artery, and a blood flow lumen extending between the proximal end and an outlet on the distal end. The cannula has an aspiration port proximate to the outlet, which communicates with an aspiration lumen. The cannula also includes an inflatable balloon attached to the cannula between the outlet and the aspiration port and capable of assuming an inflated condition for occluding a blood vessel. To use the device, the distal end of the cannula is introduced into a blood vessel, such as the aorta, the outlet is oriented downstream for delivering blood, and the balloon is inflated to occlude the vessel. Fluid may then be flushed into and aspirated out through the aspiration port as desired to remove loose embolic material from the
Complete (D) transposition of the great vessels refers to complete morphological reversal of the aorta and the pulmonary artery. This produces a circulation which is completely pulmonary on one side and completely systemic on the other (i.e., they are operating in parallel). Without a preexisting defect such as a ventricular septal defect or a persistent ductus arteriosus to allow for some mixing of systemic and pulmonary circulations, life cannot be sustained. Corrected (L) type transposition describes a condition in which the normal pattern of circulation is intact, but the left and right ventricles are switched. This produces a situation in which an intrinsically weaker muscle (the right ventricle) is forced to sustain a systemic blood pressure, and the stronger left ventricle forces blood through the pulmonary tree at a relatively higher flow pressure which is deleterious to the delicate pulmonary vascular tree. Thus, this condition will present clinically in a similar fashion to type D ...

A balloon floats because it has buoyancy, a lifting power given it by the gas inside it. Some gases are heavier than air and some lighter.. It is only when a balloon is filled with a gas lighter than the air outside it that it will rise. Carbon dioxide, which you blow into a balloon from your mouth is one such gas which is lighter than air. Helium is another.. A balloon filled with helium will stay airborne as long as the gas inside and the equipment attached to it (basket, string, etc.) weigh less than the air in which it is floating.. The balloon will rise until it reaches that height where the weight of the air outside the balloon equals the weight of the air inside it. At that point, it begins to float.. Gradually, though, the air inside does begin to leak out and the balloon starts to fall to earth.. ...
A balloon catheter is provided with engagement elements disposed within the balloon so that, upon inflation of the balloon, the engagement elements move in the proximal to distal direction of the catheter so as to abut one another and form a substantially rigid column to maintain alignment of the distal end of the balloon with the proximal end of the balloon and with the catheter.

Selecting this weeks Fonzie was quite an adventure. I originally considered making the Balloon Boy himself the Fonzie of the Week, back when we all thought he was up soaring the wild blue yonder - or possibly dead from falling out of the balloon. And then we all found out that he wasnt in the balloon at all. What a letdown! Dont get me wrong, Im glad the kid is safe. But you dont become Fonzie of the Week by not engaging in crazy and/or dangerous stunts. You become Fonzie of the Week by contributing to the delinquency of a minor as part of an elaborate and poorly thought-out hoax. Its actually very Fonzie-like if you think about it: cant you just imagine the shenanigans Fonzie and the gang could get themselves into with a hot air balloon? In recognition of his sitcom-worthy scheme and the criminal charges soon to be leveled against the Balloon Boys father, Im naming Richard Heene Fonzie of the Week..

Minimally invasive surgery is currently being advocated in the field of cardiac surgery.18 Median sternotomy remains the standard approach used by most cardiac surgeons, but alternative approaches such as anterolateral thoracotomy have been developed over time.19,20 The current minimally invasive approaches for ASD closure with cardiopulmonary bypass, however, are intended to make the skin incision small or less prominent for cosmetic reasons, and a truly less-invasive approach without cardiopulmonary bypass is still needed.. Although several devices have become available since the first successful attempt at per-catheter ASD closure21-23, they have all been associated with occasional complications.24 The Amplatzer Septal Occluder has recently been developed as a new device,25 and although some favorable results compared with conventional surgical closure have been reported,26-28 limitations remain, including the need for patient selection in terms of age, body weight, and type of ASD, as well ...
Background and Aim: Endoscopic submucosal dissection (ESD) enables complete, collective removal of gastrointestinal (GI) malignant tumors, but requires a long operation time. Air insufflated during ESD is distributed throughout the entire GI tract, and thus causes an enlarged feeling of the abdomen. We aimed to reduce the incidence of an enlarged feeling of the abdomen by wedging a balloon in the bulbus duodeni to reduce air flow into the lower parts of the GI tract.. Methods: Sixteen patients who were approved by the institutional ethics committee and provided consent to participate in this single-center, prospective study were divided into two groups using a sealed-envelope randomization method: ESD with a balloon wedged in the bulbus duodeni (the balloon [+] group) or conventional ESD with no balloon (the balloon [−] group). Total air volume in the entire GI tract and its change before and after ESD were measured objectively by 3-D computed tomography.. Results: In the balloon (+) group, ...
We describe a case of 43-year-old man with transcatheter closure of atrial septal defect (ASD) with the Amplatzer Septal Occluder that was embolized to the main pulmonary artery. Echocardiography could not identify the occluder device at the interatrial septal position. Tomography confirmed its dislocation (Figure 1). Silent device dislodgement which is a rare complication in terms of being asymptomatic was managed immediately. It was removed via pulmonary arteriotomy (Figure 2A and B) and the ostium secundum ASD without inferior rim was closed by using an autologous pericardial patch on total cardiopulmonary bypass. His postoperative period was uneventful.. Key words: Device Removal; Heart Septal Defects, Atrial; Septal Occluder Device ...

N2 - Transcatheter closure of a membranous ventricular septal defect (MVSD) is much more difficult than closure of other intracardiac defects because of the proximity to the aortic and tricuspid valves and their relatively large size in small children. In this repot, transcatheter closure of naturally occurring membranous VSDs was attempted in 12 Yucatan minipigs. The prosthesis is constructed from fine Nitinol wires in the shape of two buttons and a connecting waist filled with polyester fiber. Two kinds of prosthesis were used in this study: concentric and eccentric left-sided retention disks. A 6 or 7 Fr delivery sheath was advanced across the ...

  • On the basis of the hemodynamic findings, permanent balloon occlusion was carried out without complications. (ajnr.org)
  • On the basis of the hemodynamic and clinical findings during BTO, permanent occlusion of the affected segment of the sinus with a detachable balloon was carried out to minimize the risk of hemorrhagic complications during surgery. (ajnr.org)
  • MATERIALS AND METHODS: Between February 2000 and October 2004, 16 patients with hepatobiliary disease underwent single-level dynamic computed tomography during hepatic arteriography (SLD-CTHA) under temporary balloon occlusion of an intrahepatic portal vein. (biomedsearch.com)
  • Animals in the NO group underwent direct placement of a temporary vascular shunt (TVS) at the injury site, whereas animals in the CO and BO groups underwent aortic occlusion before TVS placement. (unl.edu)
  • In its July 2012 committee opinion, the ACOG panel wrote, "Current evidence is insufficient to make a firm recommendation on the use of balloon catheter occlusion or embolization to reduce blood loss and improve surgical outcome, but individual situations may warrant their use. (radiologytoday.net)
  • 18 By virtue of complete occlusion and poststenting complete graft evacuation, the PercuSurge device theoretically prevents embolization of all particles, no matter how small, as well as of soluble mediators released during stenting. (ahajournals.org)
  • Clinical experience from prospective controlled non-randomized case series with fetoscopic tracheal balloon occlusion has seen improved survival rates in contrast to untreated controls. (clinicaltrials.gov)
  • Therefore, the purpose of this randomized clinical trial in a less severely affected subgroup of patients is whether by fetoscopic tracheal occlusion, the intensity of postnatal intensive care therapy might be reduced. (clinicaltrials.gov)
  • gave an interesting account of the clinical use of stents to prevent occlusion and restenosis. (wikipedia.org)
  • In the two other cases, aortic occlusion was implemented allowing the surgeon to enter the abdomen and repair obvious findings. (hqmeded.com)
  • Ischemic events during coronary artery balloon occlusion. (wikipedia.org)
  • To evaluate the tolerance to surgical sacrifice, we performed preoperative BTO of the sigmoid sinus, with the measurement of venous pressure upstream from the balloon before and during its inflation. (ajnr.org)
  • Sniper balloon and atraumatic tip designs have been advanced to occlude larger vessels and enhance the ability for Sniper to track inside vessels. (compelo.com)
  • We aimed to reduce the incidence of an enlarged feeling of the abdomen by wedging a balloon in the bulbus duodeni to reduce air flow into the lower parts of the GI tract. (wiley.com)
  • The balloon then blocks the artery, temporarily stopping the blood flow. (isrctn.com)
  • However, the parts of the body below the balloon are cut off from the normal blood flow and this may result in short- or longer-term problems. (isrctn.com)
  • The occlusions were performed for 5 minutes but interrupted if systolic blood pressure dropped below 40 mmHg. (diva-portal.org)
  • Sixteen patients who were approved by the institutional ethics committee and provided consent to participate in this single-center, prospective study were divided into two groups using a sealed-envelope randomization method: ESD with a balloon wedged in the bulbus duodeni (the balloon [+] group) or conventional ESD with no balloon (the balloon [−] group). (wiley.com)
  • SLD-CTHA was undertaken to clarify the time-attenuation curve influenced by portal vein occlusion, and it was performed continuously over a period of 30s. (biomedsearch.com)
  • The balloon-occluded portal branch enhancement in 15 of 16 cases (94%) appears due to arterio-portal communications. (biomedsearch.com)
