Distal Vessel Occlusions

Relationship Between Lesion Topology and Clinical Outcome in Anterior Circulation Large Vessel Occlusions.

BACKGROUND AND PURPOSE Diffusion-weighted imaging (DWI) Alberta Stroke Program Early CT Score (ASPECTS), a surrogate of infarct volume, predicts outcome in anterior large vessel occlusion strokes. We aim to determine whether topological information captured by DWI ASPECTS contributes additional prognostic value. METHODS Adults with intracranial internal carotid artery, M1 or M2 middle carotid...

Balloon occlusion tests and therapeutic vessel occlusions revisited: when, when not, and how.

Nampt/PBEF/visfatin serum levels: a new biomarker for retinal blood vessel occlusions

The main objective of the study was to quantify serum levels of nicotinamide phosphoribosyltransferase (Nampt/pre-B-Cell colony-enhancing factor 1/visfatin) in subjects with a history of retinal vascular occlusions (RVOs), disease conditions characterized by pronounced ischemia, and metabolic energy deficits. A case-control study of 18 subjects with a history of RVO as well as six healthy volun...

Penumbra system: a novel mechanical thrombectomy device for large-vessel occlusions in acute stroke.

BACKGROUND AND PURPOSE Large IC artery occlusion is often resistant to recanalization. We present our initial experience with the PS. MATERIALS AND METHODS Presenting with a severe acute ischemic stroke, the first 27 consecutive patients were considered for thromboaspiration therapy and retrospective data base analysis. All patients received standard thrombectomy treatment as monotherapy or i...

Mechanical Thrombectomy in the Treatment of Distal Occlusions during Coil Embolization of Ruptured Intracranial Aneurysms

The experience in the management of thromboembolic complications of distal vessels during coil embolization using stent-retrievers in the setting of subarachnoid hemorrhage (SAH) is still limited. We report a case of 58-year-old woman with a ruptured small anterior communicating aneurysm who experienced during coil embolization a thromboembolic occlusion of the upper post-bifurcation branch of ...
