Blockage of an artery due to passage of a clot (THROMBUS) from a systemic vein to a systemic artery without its passing through the lung which acts as a filter to remove blood clots from entering the arterial circulation. Paradoxical embolism occurs when there is a defect that allows a clot to cross directly from the right to the left side of the heart as in the cases of ATRIAL SEPTAL DEFECTS or open FORAMEN OVALE. Once in the arterial circulation, a clot can travel to the brain, block an artery, and cause a STROKE.

The endovascular management of blue finger syndrome. (1/776)

OBJECTIVES: To review our experience of the endovascular management of upper limb embolisation secondary to an ipsilateral proximal arterial lesion. DESIGN: A retrospective study. MATERIALS AND METHODS: Over 3 years, 17 patients presented with blue fingers secondary to an ipsilateral proximal vascular lesion. These have been managed using transluminal angioplasty (14) and arterial stenting (five), combined with embolectomy (two) and anticoagulation (three)/anti-platelet therapy (14). RESULTS: All the patients were treated successfully. There have been no further symptomatic embolic episodes originating from any of the treated lesions, and no surgical amputations. Complications were associated with the use of brachial arteriotomy for vascular access. CONCLUSIONS: Endovascular techniques are safe and effective in the management of upper limb embolic phenomena associated with an ipsilateral proximal focal vascular lesion.  (+info)

Thromboatheromatous complications of umbilical arterial catheterization in the newborn period. Clinicopathological study. (2/776)

Severe catheter-related thromboatheromatous lesions were found at necropsy in 33 of 56 infants who had umbilical arterial catheters passed during life. In infants dying within 8 days of insertion of the catheter, varying degrees of thrombosis of the aorta and its major branches were seen. With increasing thrombosis and aging of the thrombus, fatty deposits were seen first within the thrombus, and then in the intima and media. In addition there was evidence of proliferation of medial smooth muscle cells and of disruption of the medial architecture below the thrombus, characterized by the presence of abundant mucopolysaccharide. In infants who survived longer, varying degrees of organization of the thrombus could be traced, leading eventually to raised fibrous plaques with lipid and occasionally calcification. The lesions in the older infants were similar in many respects to experimental thromboatheromatous lesions produced in rabbits, and to some lesions of artheroma occurring spontaneously in humans. A wide variety of embolic phenomena were found, with features suggesting asynchrony of embolic episodes. The presence of thrombotic lesions could not be related to birthweight, Apgar scores at 1 and 5 minutes, age at catheterization, duration of catheterization, underlying disease process, age at death or the presence of hypothermia, acidosis, or anomalies in coagulation tests. There is a need for less hazardous methods of monitoring arterial oxygen tension.  (+info)

Mechanisms of retarded apical filling in acute ischemic left ventricular failure. (3/776)

BACKGROUND: We examined the hypothesis that retardation of apical filling as measured by color M-mode Doppler echocardiography in the diseased left ventricle (LV) reflects a decrease in the intraventricular mitral-to-apical pressure gradient. METHODS AND RESULTS: In 9 open-chest anesthetized dogs, micromanometers were placed near the mitral tip and in the apical region. From the color M-mode Doppler images, the time delay (TD) between peak velocity at the mitral tip and the apical region was determined as an index of LV flow propagation. Acute ischemic LV failure was induced by coronary microembolization. Induction of ischemia caused a marked increase in LV end-diastolic pressure and a decrease in LV ejection fraction. The time constant of LV isovolumic apical pressure decay (tau) increased from 31+/-8 to 49+/-16 ms (P<0.001). The peak early diastolic mitral-to-apical pressure gradient (DeltaPLVmitral-apex) decreased from 1.9+/-0.9 to 0.7+/-0.5 mm Hg (P<0.01), and TD increased from 5+/-3 to 57+/-26 ms (P<0.001). The slowing of flow propagation was limited to the apical portion of the LV cavity. The TD correlated with DeltaPLVmitral-apex (r=-0.94, P<0.01) and with tau (r=0.92, P<0.01). Before ischemia, the mitral-to-apical flow propagation velocity far exceeded the velocity of the individual blood cells, whereas during ischemia, flow propagation velocity approximated the blood velocity. CONCLUSIONS: Retardation of apical filling in acute ischemic failure was attributed to a decrease in the mitral-to-apical driving pressure, reflecting slowing of LV relaxation. The slowing of flow propagation appeared to represent a shift in apical filling from a pattern of column motion to a pattern dominated by convection.  (+info)

Should initial clamping for abdominal aortic aneurysm repair be proximal or distal to minimise embolisation? (4/776)

OBJECTIVES: to determine whether clamping proximally or distally on the infrarenal aorta during abdominal aortic aneurysm (AAA) repair increases the overall embolic potential. MATERIALS AND METHODS: a sheath was placed in the mid-infrarenal aorta of 16 dogs. In eight animals a cross-clamp was placed at the aortic trifurcation, and in another eight animals it was placed in the immediate subrenal position. Under fluoroscopy blood flow within the infrarenal aorta was evaluated by contrast and particle injections. Grey-scale analysis was used to calculate contrast density. Particle distribution was followed fluoroscopically and confirmed pathologically. RESULTS: fifty-seven+/-24% of injected contrast remained within the aorta with distal clamping while 97+/-7% did so with proximal clamping (p<0.01). With distal aortic clamping 6.2+/-1. 3 out of 10 injected particles remained within the aorta after 15 seconds and only 0.8+/-0.8 remained after 5 min. With proximal aortic clamping, all 10 of the particles remained within the aortic lumen for the full 5 minutes (p<0.001). CONCLUSIONS: initial distal clamping minimises distal embolisation, but may result in renal and/or visceral embolisation. Initial proximal clamping prevents proximal embolisation and does not promote distal embolisation. We recommend initial proximal clamping in aortic aneurysm surgery to minimise the overall risk of embolisation.  (+info)

Atrial fibrillation in general practice: how useful is echocardiography in selection of suitable patients for anticoagulation? (5/776)

All patients identified from records in two practices in West Lothian (n = 103) as having atrial fibrillation (AF) were offered a clinical examination, electrocardiogram (ECG), and echocardiography. Sixty-five patients attended the examinations. Of these, 26 (40%) were found to be in sinus rhythm. Many of those in AF were already on warfarin. Only eight who were found to have AF, who were not already on warfarin and who had no contraindications to it, had additional risk factors that suggested they be treated with warfarin. In no case did echocardiography alter management decisions.  (+info)

Acetylsalicylic acid reduces vegetation bacterial density, hematogenous bacterial dissemination, and frequency of embolic events in experimental Staphylococcus aureus endocarditis through antiplatelet and antibacterial effects. (6/776)

BACKGROUND: Platelets are integral to cardiac vegetations that evolve in infectious endocarditis. It has been postulated that the antiplatelet aggregation effect of aspirin (ASA) might diminish vegetation evolution and embolic rates. METHODS AND RESULTS: Rabbits with Staphylococcus aureus endocarditis were given either no ASA (controls) or ASA at 4, 8, or 12 mg. kg-1. d-1 IV for 3 days beginning 1 day after infection. Vegetation weights and serial echocardiographic vegetation size, vegetation and kidney bacterial densities, and extent of renal embolization were evaluated. In addition, the effect of ASA on early S aureus adherence to sterile vegetations was assessed. In vitro, bacterial adherence to platelets, fibrin matrices, or fibrin-platelet matrices was quantified with either platelets exposed to ASA or S aureus preexposed to salicylic acid (SAL). ASA at 8 mg. kg-1. d-1 (but not at 4 or 12 mg. kg-1. d-1) was associated with substantial decreases in vegetation weight (P<0.05), echocardiographic vegetation growth (P<0.001), vegetation (P<0.05) and renal bacterial densities and renal embolic lesions (P<0.05) versus controls. Diminished aggregation resulted when platelets were preexposed to ASA or when S aureus was preexposed to SAL (P<0.05). S aureus adherence to sterile vegetations (P<0.05) or to platelets in suspension (P<0.05), fibrin matrices (P<0.05), or fibrin-platelet matrices (P<0.05) was significantly reduced when bacteria were preexposed to SAL. CONCLUSIONS: ASA reduces several principal indicators of severity and metastatic events in experimental S aureus endocarditis. These benefits involve ASA effects on both the platelet and the microbe.  (+info)

Prevention of distal embolization during saphenous vein graft lesion angioplasty. Experience with a new temporary occlusion and aspiration system. (7/776)

BACKGROUND: Repeat coronary artery bypass graft surgery (CABG) is associated with a high morbidity and mortality, rendering percutaneous treatment of saphenous vein graft (SVG) lesions an attractive alternative. However, percutaneous interventions of degenerated SVGs carries high risk of distal embolization. METHODS AND RESULTS: This study reports our initial experience with the PercuSurge GuardWire, a new device developed to prevent embolization during treatment of degenerated SVG. This device consists of a 190-cm-long, hollow 0.014-in guidewire with a central lumen connected to a distal occlusion balloon. A dedicated inflation device (the MicroSeal Adapter) was used to inflate the distal balloon and maintain complete lumen occlusion during balloon dilatation and stent implantation. A monorail aspiration catheter, connected to a vacuum syringe, was used to evacuate atherosclerotic and thrombotic debris. Angioplasty with stent implantation was performed in 15 degenerated SVGs (18 lesions). Procedural success was achieved in all patients with normal postprocedure flow (Thrombolysis in Myocardial Infarction grade 3). No distal embolization was observed. There were no major in-hospital adverse clinical events, including Q-wave or non-Q-wave myocardial infarction, emergency CABG, or death. All patients were asymptomatic at discharge. CONCLUSIONS: This preliminary series supports the feasible use of the PercuSurge GuardWire for retrieval of plaque debris and prevention of embolization in degenerated SVGs. The good tolerance of temporary occlusions without angiographic or clinical evidence of distal embolization represents encouraging early findings.  (+info)

Retrieval and analysis of particulate debris after saphenous vein graft intervention. (8/776)

OBJECTIVES: This study was designed to evaluate the composition and quantity of particulate debris resulting from vein graft intervention. BACKGROUND: Distal embolization and "no reflow" are frequent and important complications resulting from angioplasty of diseased saphenous vein grafts. Little is known about the composition and quantity of embolic particulate debris associated with vein graft intervention, and no intervention has been shown to protect against its clinical consequences. METHODS: A catheter system, designed to contain, retrieve and protect against distal embolization of this material, was evaluated during 27 percutaneous interventional saphenous vein graft procedures. Clinical, angiographic and pathologic analyses were performed. RESULTS: The duration of distal graft occlusion required to allow intervention and subsequent debris removal was 150 +/- 54 s, decreasing as experience was gained. Thrombolysis in Myocardial Infarction trial (TIMI) flow grade increased from 2.6 +/- 0.8 to 3.0 +/- 0.0. Creatine kinase (CK) rose above normal in three patients (11.1%) exceeding 3x normal in one (3.7%) resulting in the diagnosis of non-Q-myocardial infarction. Particulate material was identified following 21 of 23 procedures suitable for analysis. Particle size was 204 +/- 57 microm in the major axis and 83 +/- 22 microm in the minor axis. Particles consisted predominantly of soft acellular atheromatous material, such as that typically found under a fibrous cap. Semiquantitative analysis suggested that the quantity of particulate material was less following stenting than following balloon dilation. CONCLUSIONS: Particulate matter is commonly present following routine angioplasty and stenting of saphenous vein grafts. Containment, retrieval and analysis of this particulate debris are all feasible. Comparison to prior clinical experience is limited by small sample size. However, to the extent that these particles may contribute to distal embolization, no-reflow and infarction, such a system may contribute to the reduction of complications following vein graft intervention.  (+info)

Our results show that SWI is more sensitive than MRA for detecting a thrombus in acute cardioembolic stroke, and it is especially sensitive for detecting a single thrombus or multiple thrombi in distal intracranial arteries. MRA is useful in evaluating intracranial arteries, but it has a limitation in terms of visualizing abnormalities of distal intracranial arteries because of its insensitivity to slow flow or slow in-plane flow [13]. The SVS has been first reported through a study using T2*-weighted MRI [14]. However, the detection rate of the SVS is inconsistent among previous studies conducted using GRE: the heterogeneous etiologies of the enrolled stroke patients may affect the inconsistent sensitivity of the SVS on GRE [13-15]. The study of Cho et al. showed that the SVS on GRE was detected in 47.4% of 95 patients, especially in 77.5% of 40 patients with cardioembolic stroke [8]. Furthermore, a recent study conducted using SWI in acute posterior cerebral artery infarction showed that ...
Looking for arterial embolism? Find out information about arterial embolism. 1. of, relating to, or affecting an artery or arteries 2. denoting or relating to the usually bright red reoxygenated blood returning from the lungs or... Explanation of arterial embolism
Arterial embolism is a sudden interruption of blood flow to an organ or body part due to an embolus adhering to the wall of an artery blocking the flow of blood, the major type of embolus being a blood clot (thromboembolism). Sometimes, pulmonary embolism is classified as arterial embolism as well, in the sense that the clot follows the pulmonary artery carrying deoxygenated blood away from the heart. However, pulmonary embolism is generally classified as a form of venous embolism, because the embolus forms in veins. Arterial embolism is the major cause of infarction (which may also be caused by e.g. arterial compression, rupture or pathological vasoconstriction). Symptoms may begin quickly or slowly depending on the size of the embolus and how much it blocks the blood flow. Symptoms of embolisation in an organ vary with the organ involved but commonly include: Pain in the involved body part Temporarily decreased organ function Later symptoms are closely related to infarction of the affected ...

Objective: Few studies have reported the outcome of mechanical thrombectomy with Solitaire stent retrival (MTSR) in subtypes of acute ischemic stroke. The purpose of this study was to evaluate the efficacy and result of MTSR in acute cardioembolic stroke. Methods: Twenty consecutive patients with acute cardioembolic stroke were treated by MTSR. The angiographic outcome was assessed by thrombolysis in cerebral infarction (TICI) grade. TICI grade 2a, 2b, or 3 with a measurable thrombus that was retrieved was considered as a success when MTSR was performed in the site of primary vessel occlusion, and TICI grade 2b or 3 was considered as a success when final result was reported ...
This is a brief review of the literature on coronary embolism and a case report of a very unique type of coronary embolus-a piece of calcium from a calcified aortic valve. Microscopic sections revealed that the calcium plaque was covered by endothelium which had grown out from the vessel wall, thus attaching it to the coronary artery. The patient lived approximately two months after the embolism occurred.. ...
The presence of thrombi in the atherosclerotic and/or aneurysmatic aorta with peripheral arterial embolism is a common scenario. Thrombus formation in a morphologically normal aorta, however, is a rare event. A 50 years old woman was admitted to the mergency department for pain, coldness, and anesthesia in the the left foot. She had a 25 years history of cigarette smoking, a history of postmenopausal hormone replacement therapy (HRT), hypercholesterolemia and hyperfibrinogenemia. An extensive serologic survey for hypercoagulability, including antiphospholipid antibodies, and vasculitis disorders was negative. Transesophageal echocardiography revealed a large, pedunculated and hypermobile thrombus attached to the aortic wall 5 cm distal of the left subclavian artery. The patient was admitted to the surgery department, where a 15 cm long fresh, parietal thrombus could be removed from the aorta showing no macroscopic wall lesions or any other morphologic abnormalities.

Annually, an estimated 1,285,000 in-patient angioplasty procedures, 1,471,000 inpatient diagnostic cardiac catheteri-zations and 68,000 inpatient defibrillator implantations are performed. The direct and indirect cost of cardiovascular diseases for 2007 is approximately $431.8 billion. The occurrence of plaque rupture with subsequent microemboli of atherosclerotic and thrombolytic debris into small coronary vessels has been confirmed. Microinfarction results from microemboli that are shed following coronary interventions. The aims of this review are to: 1) detect heterogeneous microinfarction using viability imaging, 2) characterize the consequences of distal coronary microembolization on left ventricle function and perfusion and 3) illustrate the progress of non-invasive imaging modalities in assessing distal coronary microembolization.
Note on unexplained Spinal Injury & Spinal Stroke Following extensive investigation of the causes of spinal strike without apparent explanation, the following case has been proven by a team of bio mech engineers, leading neurologists and other contributors in the spinal research field. A scientific paper is being prepared for publication. 1. Spinal stroke may occur many weeks or months after a primary event involving sudden straightening of the spine due to physical trauma such as
This condition is quite common in dogs although it is very rare in cats. It is really a type of stroke that affects the spinal cord instead of the brain. In this case the stroke is caused by small pieces of disc material that somehow get into the blood vessels supplying the spinal cord to cause a blockage. Clinical signs are therefore very sudden in onset and often cause immediate paralysis of one limb, of the rear limbs or sometimes of all four limbs. The animals may be painful initially but the pain usually resolves completely within a few hours. Diagnosis depends on ruling out other potential causes of the signs such as a [intlink id=1466″ type=post]fracture[/intlink] or [intlink id=1436″ type=post]disc disease[/intlink]. There is no treatment although physical therapy has been shown to influence recovery favorably. The completeness of the animals recovery depends mainly on how much of the spinal cord has been damaged by the injury and this is best determined by a neurological ...
Response:. We appreciate the attention of Guedes and Ferro to our meta-analysis of randomized controlled trials on the efficacy and safety of anticoagulant treatment in acute cardioembolic stroke.1 Indeed, our paper was submitted to Stroke on April 26, 2006, and thus before the ENS meeting held in September 2 to 5, 2006. After updating the meta-analysis by adding the ARGIS-1 study,2 Guedes and Ferro confirmed that the routine use of anticoagulants in the first 48 hours after an ischemic stroke of presumed cardioembolic origin cannot be recommended because of a bleeding excess. However, they found a favorable effect of anticoagulants on the prevention of recurrent ischemic stroke or stroke of unknown cause (odds ratio 0.64, CI between 0.47 to 0.88).. We would like to make a comment on the statistical analysis performed in this update meta-analysis. The authors used a fixed-effect model. Our understanding is that random effects models are recommended if heterogeneity through the studies is ...
1. Introduction. Acute mesenteric ischemia (AMI) due to an embolism of the superior mesenteric artery (SMA) is a surgical emergency associated with a high mortality rate due to the difficulty in recognizing the condition before bowel infarction occurs. These thromboembolic events consist of multiple emboli in over twenty per cent of cases, which worsens the prognosis. We could find only one case of embolic episode in a lower limb following a SMA embolism that has been previously reported in the literature [1] . We hereby report a new case of AMI due to embolism of the SMA associated with lower limb acute ischemia.. 2. Case Presentation. A 62-year-old man, chronic smoker, was admitted to the emergency department complaining of history of abdominal pain since 2 days. Our patient was hemodynamically stable with temperature at 37.9˚C, and blood pressure was 120/80 mmHg. Abdominal examination was marked by diffuse abdominal tenderness, and limb examination showed bilateral toes ischemia (Figure 1). ...
Background and Purpose: A recent study showed that cardiogenic emboli might flow more frequently into the right hemisphere, whereas atheromatous aortic arch emboli might flow more frequently into the left hemisphere. We tried to 1) see if cardioembolic (CE) infarct volume would be larger in the right hemisphere than in the left hemisphere, and 2) depict anatomical regions showing CE vs. large artery atherosclerotic (LAA) infarction-related right-left propensity.. Methods: In this study on carotid artery territory CE (n = 694) vs. LAA (n = 1162) acute ischemic stroke patients who were enrolled consecutively from 11 nationwide stroke centers, we quantitatively registered diffusion magnetic resonance imaging lesions onto the Montreal Neurologic Institute brain template.. Results: In patients with bilateral CE stroke (n = 163), right hemispheric infarct size was about two times bigger than the contralateral left hemispheric infarct size (p = 0.002). However, in patients with either unilateral (n = ...

Results: After surgery, new lesions were identified in 31% of patients, averaging 0.5 lesions per patient (67 mm3 [0.004%] of brain tissue). Patients with preexisting lesions were 10× more likely to receive new lesions after surgery than patients without preexisting lesions. Preexisting ischemic lesions were observed in 64% of patients, averaging 19.4 lesions (1542 mm3 [0.1%] of brain tissue). New lesions in the left hemisphere were significantly smaller and more numerous (29 lesions; median volume, 44 mm3; volume range, 5-404 mm3) than those on the right (10 lesions; median volume, 128 mm3; volume range, 13-1383 mm3), which is consistent with a cardioembolic source of particulate emboli. Overall, the incidence of postoperative cognitive decline was 46% and was independent of whether new lesions were present ...
Sometimes referred to by the older term cerebrovascular accident (CVA), a stroke is the rapid loss of brain function due to disturbance in the blood supply to the brain. This can be due to ischemia (lack of blood flow) caused by blockage (thrombosis, arterial embolism, blood cot) or a hemorrhage. As a result, the affected area of the brain cannot function, which might result in an inability to move one or more limbs on one side of the body, inability to understand or formulate speech or an inability to see one side of the visual field ...
Some eighteen months ago my father, whom I loved very much, died from arterial embolism. There wasnt a single day since I did not cry, and I just wished that something would happen to take my mind of things. Then my wife suffered a stroke, which just shows that you should be careful what you wish for.. Or maybe not. For the better or the worse, the universe is not moved by our wishes, and things do not usually happen for a reason. This is in fact my single comfort in these times, that events did not happen because we did anything wrong, or because we are somehow bad people, or we failed to do or not do something that we should or shouldnt have done. Events occurred as they did simply because something always happens to somebody, only the things that happened to us were pretty bad.. What happened is this.. On January 11th Siobhan, my wife, called me at work and asked if I could return home immediately; she had caught a flu, or so she thought, and needed me to look after her. When I got home she ...

N2 - Endovascular management of cardiovascular disease is quickly becoming a more popular treatment. The effectiveness in using embolic protection devices (EPDs), such as the Angioguard™ XP filter, during carotid artery stenting (CAS) is a topic of ongoing controversy and scrutiny. Early clinical results indicate that EPDs can reduce complications associated with CAS. However, the incidence of stroke and postprocedural embolic events are statistically similar when comparing CAS with the gold standard in carotid stenosis repair, carotid endarterectomy (CEA). The focus of this manuscript is the critical evaluation of Angioguard XP with respect to numerous in vitro and ex vivo experiments, and clinical trials that have been conducted by the authors and other researchers to investigate the efficacy of EPDs with the objective of ...

This prospective cohort study shows that the Export and Diver catheters are both safe and effective in removing thrombus in an unselected population with ST-segment elevation myocardial infarction. The larger internal lumen diameter of the Diver catheter did not result in retrieval of larger thrombotic particles, nor in improved angiographic or electrocardiographic outcomes.. Primary PCI does not always result in successful reperfusion of the myocardium, despite a patent epicardial vessel. Mechanical crushing and fragmentation of the thrombus-containing lesion during primary PCI is thought to be at least partly responsible for myocardial dysfunction after PCI (13-15). Several devices have been introduced to facilitate removal of thrombus and plaque material, thereby protecting the microvasculature and improving myocardial blood flow. In saphenous vein graft PCI, distal embolic protection devices have proven to be very effective in preventing distal embolization (class I recommendation, level of ...
A deployment control system provides controlled deployment of an embolic protection device which may include a guide wire, an expandable filter attached to the guide wire near its distal end, and a restraining sheath that maintains the expanded filter in a collapsed position. The deployment control system includes a torque control device which allows the physician to torque the guide wire into the patients anatomy and a mechanism for preventing the guide wire from buckling as the restraining sheath is being retracted to deploy the expandable filter. A recovery control system for recovering the embolic protection device includes an inner catheter which extends within a lumen of an outer recovery sheath in a coaxial arrangement. A distal portion of the inner catheter extends beyond another recovery sheath during advancement of the recovery system into the vasculature. The recovery sheath can be advanced over the inner catheter to collapse the expandable filter. The proximal ends of the inner catheter and
An elongate distal protection device includes an intraluminal filter-occluder combination positioned at a distal end thereof. An expandable occluder is disposed within an expandable filter such that the filter and occluder are independently deployable. During use, the expanded occluder may be used first to stop embolic particles for aspiration thereof. Then, the occluder may be collapsed, leaving the filter expanded to capture any remaining embolic particles.

N2 - Introduction: Since 1993 an operative technique without adjuvant therapy (laterally extended parametrectomy, the LEP procedure) has been in use at our institution for the treatment of Stage IIB cervical cancer and for patients with pelvic lymph node metastases in Stages IA-IIA. Iliac/femoral artery embolic occlusion in the cohort of LEP operated patients was studied in an 11 years long period. Methods: The LEP-Wertheim procedure was used in 320 patients between 1994 and 2005. Embolic occlusion of the iliac and/or femoral arteries was detected in four out of 255 (1.6%) cases. Thrombectomy was done on one blood vessel in three cases, on both the deep and superficial femoral arteries in one case were executed to restore the vessel patency. Results: Three out of four patients ...
Dr. Myla describes the teams experience with the new embolic protection device: The low crossing profile and integration of a primary guidewire shortened procedure time, and facilitated lesion crossing and filter placement, especially in the presence of tortuous anatomy. The 0.014 guidewire tip demonstrated good torque response and the guidewire provided excellent support…it was ideal for procedures in which tortuosity would preclude placement of a more structured DPD with a stiff delivery catheter. Conformability of the expanded fiber network to the vessel wall and the short landing zone of the device made it ideal for challenging anatomy distal to the lesion. Anecdotally, investigators have commented the FiberNet EPS resulted in fewer vessel spasms..

A 44 year old man presented with intermittent claudication of the right lower leg and a history of surgical repair for aortic coarctation at the age of 12 years. Right popliteal and pedal pulses were diminished, and a 3/6 mesosystolic heart murmur was most clearly audible over the posterior part of the thorax. Systolic blood pressure was slightly raised equally in both arms, and a systolic ankle/arm pressure gradient that was higher on the right than on the left side (75 mm Hg and 45 mm Hg, respectively) was found. Ultrasound showed a mass in the right popliteal artery causing severe stenosis. Angiography revealed two structures in the middle and just before the bifurcation of the popliteal artery (far left). Based on these findings, a subacute popliteal artery embolism was suspected. No irregularities were found in the lower aorta and iliac/femoral arteries. Other causes of the embolism, such as atrial fibrillation, endocarditis or patent foramen ovale, were excluded. ...

(HealthDay)-Retinal emboli are associated with conventional cardiovascular risk factors, stroke, and chronic kidney disease, according to a study published online Aug. 24 in JAMA Ophthalmology.
BAO is relatively rare, accounting for 6-10% of strokes. Although women tend to be affected later in life than men, most patients who develop BAO are aged 50-80. Predominant risk factors include hypertension, diabetes, ischaemic heart disease, smoking, hyperlipidaemia, previous stroke and peripheral vascular disease. The most common underlying aetiology for BAO is atherosclerosis. However embolic phenomena, vasculitis, dissection and even migraine may also be implicated. Classically, patients experience transient ischaemic attacks or a prodrome of symptoms including headache and vertigo in the weeks preceding the acute stroke [1]. However this may not always be present, as was the case with our patient who developed abnormal neurology likely secondary to embolic phenomenon from his chronic BAO. Prognosis is extremely variablewith poor outcome (defined as death, dependency, severe disability or modified Rankin score 3-6) in 54-95% of cases but factors thought to be associated with worse prognosis ...
In this endeavor, we aim to cover an updated and practical overview of the whole spectrum of this disturbing hurdle.

Thereafter, an updated look on the epidemiology that has been exponentiating the awareness on this arrhythmia with a special scrutiny to the impact on stroke units worldwide is discussed. In the next section, the main advances in the diagnostic area will be presented, ranging from the anatomical viewpoint to rhythm disturbances and embolic complications. The medical and interventional treatment will follow with critical reviews of the therapeutic outbreaks and achievements into a practical modern-day care ...
Safely targeting the neural foramen or epidural space is the goal of image-guided transforaminal CSI. Injection procedures are used to deposit steroid solution in the perineural or epidural space, while avoiding intravascular injection. Although it is a generally safe procedure, rare severe complications have been reported with CT and fluoroscopic guidance.8,14. Recently reported techniques focus on CT-guided access to the neuroaxis while minimizing the chance for embolic complications.6⇓-8 We present a cohort treated with a variation on these techniques. A lateral patient position and a near-vertical trajectory with a short 25-ga needle were combined to minimize procedural time and radiation dose. Because proportionally less soft-tissue is crossed in the lateral position, this theoretically decreases the chance that a small muscular artery will be inadvertently pierced. In addition, when comparing the needle-insertion depth by using a lateral trajectory versus a dorsal trajectory within each ...

Atrial fibrillation (AF), the most common sustained rhythm disturbance, is associated with a significantly enhanced mortality and morbidity due to thromboembolic events, and other cardiac and noncardiac complications. Therefore the Network of Competence on Atrial Fibrillation (AFNET) supported by the German Ministry for Education and Research (BMBF) was established in order to collect clinical data on patients (pts) with AF (paroxysmal, persistent, permanent) over a study period of 6 years with an expected sample size of 12,000 pts. Incidence, clinical relevance and outcome after SAE is recorded and assessed by a Critical Event Committee (CEC).. The CEC-members (experts in cardiology and neurology) defined as SAE any death with or without relationship to AF, cardio-embolic events (stroke, peripheral arterial embolism), bleeding complications due to antithrombotic therapy, acute heart failure, syncope, resuscitation; additionally, the complication of interventional strategies for AF-treatment ...

One day, I was eating dinner with the attendant auntie. I was leaning against the table on my bed when I felt something warm on my bottom. Auntie, I cried, Im bleeding! When she removed the table, both of us were at a loss. Auntie rushed to the nurse station, shouting that I was bleeding heavily. Several nurses rushed into my room and pressed upon my wound. I was very weak and sweating, and my blood pressure had declined. I was immediately sent to the intensive care unit for emergent treatment. Auntie asked my mother and brother to come to the hospital. I didnt know that I was about to die. I was still conscious, crying for them to stop the bleeding. I was then sent to the department of medical imaging to find the exact spot of the bleeding; and an artery embolism was performed to stop it. But the wound continued to grow. Soon, it was larger than an octavo, and my iliac (or loin) bone was eroded to the point of breaking. The surgeon removed my testicles because they were in a state of ...
