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.

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 ...
Occlusion Balloon Catheter Market - Global industry segment analysis, regional outlook, share, growth; occlusion balloon catheter market forecast 2017 to 2027 by future market insights
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,

Y1 - 2017/6/20. N2 - Resuscitative endovascular balloon occlusion of the aorta is a new procedure for adjunctive management of critically injured patients with noncompressible torso or pelvic hemorrhage who are in refractory hemorrhagic shock, ie, bleeding to death. The anesthesiologist plays a critical role in management of these patients, from initial evaluation in the trauma bay to definitive care in the operating room and the critical care unit. A comprehensive understanding of the effects of resuscitative endovascular balloon occlusion of the aorta is essential to making it an effective component of hemostatic resuscitation..

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.. ...
This device is a single use percutaneous catheter system that is introduced into an artery through the skin using a guidewire. The catheter has an embolic capture filter or an occlusion balloon at the distal end. The filter or balloon can be placed either distally to the lesion or proximally depending on the design of the device and intended use. The filter or balloon is used to capture embolic material in a manner that may protect or prevent a stroke or other cerebral vascular sequelae. The embolic capture device is indicated for use as a guidewire and embolic protection system to contain and remove embolic material (thrombus/debris) while performing angioplasty and stenting procedures ...
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
BACKGROUND: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a potentially life-saving but high-risk emergency procedure in patients with haemorrhagic shock. Lack of physicians with competence in the procedure is a barrier to implementation of REBOA. It is currently unclear how training and assessment of competence should be done.. OBJECTIVES: To report and evaluate research in training and assessment of competence in REBOA and femoral arterial access with the aim to investigate the effect of simulation-based training in the procedure and to provide suggestions for the future design of training programs and assessment tools.. METHODS: Following PRISMA guidelines, PubMed, Embase, and Cochrane Library databases were searched for studies on training or assessment of competence in REBOA and femoral arterial access. Bias assessment was done using the Medical Education Research Study Quality Instrument. Evidence level was assessed using GRADE.. RESULTS: Sixteen studies were ...

Objective: The goal of this work was to demonstrate technical feasibility of automated balloon pressure management during REBOA in the pre-clinical setting. Methods: This paper presents an intelligent balloon management device which automates the balloon inflation process, preventing the possibility of balloon over or under inflation, optimizes inflation pressure and if indicated, deflates automating partial REBOA to allow distal organ perfusion. Edwards TruWave pressure transducers are used to monitor the blood pressure proximal and distal to the balloon, as well as the internal balloon pressure. A faux PID controller, implemented on an Arduino platform, is used in a feedback control loop to allow a user defined mean arterial pressure setpoint to be reached, via a syringe driver which allows intelligent inflation and deflation of the catheter balloon. Results: Ex vivo testing on a vascular perfusion simulator provided the characteristic behavior of a fully occluded aorta, namely the decrease of ...
The femoral and brachial arteries were treated in eight and two patients, respectively. Technical success was confirmed in all cases, and a clinical success rate was 70% (7/10) was noted. Two patients presented with a complication of acute thrombosis at the distal arteries. In 7 patients, balloon occlusion was performed before injection of thrombin to prevent the spread of thrombin. Coil embolization of the distal branch was also performed in one of these patients ...

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 ...

Stdev BTO: 17.10 µs. Item 2 comes from the way in which the AES transmits its signals. The AES receives the unique word in the P-channel and tracks this continuously so that it can determine the correct time to transmit when necessary. The system uses a reference/sample clock at 42KHz for the IQ samples resulting in an effective reference time captured with a resolution of ~24µs. Since the clocks are not synchronised and the satellite and AES are moving, the precise time of the unique word will drift through the reference clock cycles such that the reference time error will resemble a sawtooth stepping up or down according to the direction of drift. Since there are very infrequent samples of this error, we observe an error of +/-12µs with a truncated non-Gaussian distribution.. Item 4 arises because of the 20µs resolution of the GES BTO measurement.. The MH370 SATCOM working group undertook a number of steps to validate the accuracy of the available BTO measurements during the initial stages ...

In the PROFI (Prevention of cerebral embolization by proximal balloon occlusion compared to filter protection during carotid artery stenting) trial, 62 patients undergoing carotid artery stenting with cerebral embolic protection for a ≥60 % symptomatic or ≥80% asymptomatic internal carotid artery stenosis were randomly assigned to proximal balloon occlusion or filter protection. The primary endpoint was the incidence of new cerebral ischaemic lesions as assessed by diffusion weighted magnetic resonance imaging (DW-MRI). Secondary endpoints were the number and volume of new ischaemic lesions and major adverse cardiovascular and cerebral events (MACCE).. The incidence rate of new cerebral ischaemic lesions was 87.1% in the filter group, and 45.2% in the balloon group. The mean number of new cerebral ischaemic lesions was 3.5 in the filter group and 1.0 in the balloon group. There were no significant differences in MACCE at 30 days between the two groups.. In this single centre, randomised ...

N2 - Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a hemorrhage control technique that is increasingly being adopted for the management of noncompressible bleeding. In addition to limiting hemorrhage, REBOA increases blood flow to the heart, lungs, and brain. A small number of case reports and animal studies describe the use of REBOA to increase coronary perfusion during cardiopulmonary resuscitation. We report a case in which REBOA may have reversed ST-segment abnormalities during a Type II non-ST elevation myocardial infarction (NSTEMI) in a patient with previous trauma. We describe the presentation, ...

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).

Background: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is currently evolving and being used worldwide for trauma management. Smaller sheath devices for REBOA and new advances in endovascular resuscitation methods suggest the potential for the procedure to be utilized in hemodynamically unstable non-trau-matic patients.. Methods: We describe five adult patients that underwent hemodynamic control using the 7 Fr sheath ER-REBOA™ catheters for non-traumatic hemorrhagic instability at Örebro University Hospital between February 2017 and June 2017.. Results: The ER-REBOA™ catheter was inserted and used successfully for temporary blood pressure stabilization as part of an endovascular resuscitation process.. Conclusion: The ER-REBOA™ catheter for endovascular resuscitation may be an additional method for temporary hemodynamic stabilization in the treatment of non-traumatic patients. Furthermore, the ER-REBOA™ catheter may be a potential addition to advanced cardiac life ...
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 ...
The Amplatzer Duct Occluder can accommodate large PDAs with a single device-which can aid in minimizing the complexity of the procedure.

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.
