BACKGROUND Meta-analyses of randomized trials have shown an increased risk of periprocedural stroke after carotid artery stenting (CAS) compared with carotid endarterectomy, which may differ in specific patient subgroups. Knowledge of risk factors for cerebral embolic lesions during CAS may impact treatment decisions for the individual patient, but these factors have not been extensively studie...

BACKGROUND AND PURPOSE Underlying embolic causes diagnosed by transesophageal echocardiography could be implicated in mechanisms of embolic stroke of undetermined source. We aimed to explore factors, including underlying embolic causes, related to recurrent vascular events in embolic stroke of undetermined source. METHODS Patients who fulfilled the diagnostic criteria for embolic stroke of un...

BACKGROUND Myxomas are the most common primary heart tumors and are closely associated with embolic events. Cardiac myxomas typically arise from the interatrial septum at the border of the fossa ovalis in the left atrium. Any other location is considered atypical. Embolism, one of the complications of myxoma, is associated with high morbidity and mortality. The aim of this study was to investig...

BACKGROUND Neurologic injury is a rare yet devastating outcome of coronary artery bypass grafting surgery. Mechanisms producing both focal and global neurologic injuries include embolization, cerebral hypoperfusion, and hypotension. In this present study, we report an association between variations in the treatment of the internal mammary artery with the detection of cerebral embolic signals. ...

Pulmonary arteriovenous malformation is an abnormal communication between artery and a vein, causing clinical manifestations, such as chronic hypoxemia embolic events. Arteriovenous malformations were treated surgically, with significant rate of complications. In the 1970 ́s, first percutaneous catheter embolization was performed coils. We describe three cases in which techniques effective to pr...

BACKGROUND AND PURPOSE Embolic events have long been thought to occur in patients with cardiac tumors secondary to embolization of tumor fragments; however, there are no large studies examining the epidemiology and occurrence of embolism in this group of patients. METHODS From 1957 to 2006, 323 consecutive patients with primary cardiac tumors were treated surgically at our institution. Of the...

BACKGROUND AND PURPOSE The efficacy of thrombolytic therapy for treatment of embolic stroke has been a subject of both experimental and clinical examination. The aim of this study was to compare the efficacy, in regard to reduction of volume of ischemic brain, of two different modes of administration (ie, intra-arterial and intravenous) of tissue-type plasminogen activator (TPA) given 30 minute...
