BACKGROUND In a recent study, it was reported that transcatheter arterial embolization with spherical embolic material for life-threatening hemorrhages in various cancer patients was safe and effective. Calibrated microspheres are able to access distal regions of the target arteries, which results in the disappearance of tumor staining. However, there are few reports on the pathological behavio...

BACKGROUND AND PURPOSE The purpose of this study was to determine the role of plaques >or=4 mm and thrombi (complex plaques) in the descending aorta (DAo) as an embolic high-risk source for stroke. METHODS In 63 acute stroke patients scheduled for TEE, territory and embolic pattern of brain ischemia were prospectively assessed. Multidirectional 3D MRI velocity mapping of the aorta was perform...

BACKGROUND Preservation of renal function is an important objective of renal artery stent procedures. Although atheroembolization can cause renal dysfunction during renal stent procedures, whether adjunctive use of embolic protection devices or glycoprotein IIb/IIIa inhibitors improves renal function is unknown. METHODS AND RESULTS One hundred patients undergoing renal artery stenting at 7 ce...

BACKGROUND AND PURPOSE Although embolization with detachable coils is an accepted alternative to surgical clipping, a major long-term problem is aneurysm recanalization due to coil compaction. Liquid embolic agents are a possible alternative as filling material that might decrease the recanalization rate. We evaluated the use of a liquid embolic for endovascular treatment of intracranial aneury...

BACKGROUND AND PURPOSE Limited data exists regarding the relationship between left ventricular systolic dysfunction (LVSD) and heart failure (HF) symptoms and embolic risk among patients with atrial fibrillation. METHODS Participants in the Atrial Fibrillation Clopidogrel Trial With Irbesartan for Prevention of Vascular Events (ACTIVE) trials with HF, but not randomized to oral anticoagulatio...

BACKGROUND AND PURPOSE Stent retriever-assisted thrombectomy promotes high recanalization rates in acute ischemic stroke. Nevertheless, complications and failures occur in more than 10% of procedures; hence, there is a need for further investigation. MATERIALS AND METHODS A total of 144 patients with ischemic stroke presenting with large-vessel occlusion were prospectively included. Patients ...
