Abstract

The American Heart Association/American Stroke Association guidelines strongly recommend a noninvasive intracranial vascular study such as computed tomographic (CT) angiogram in acute stroke patient if endovascular treatment is contemplated. The objective was to determine the frequency of change in occlusion site between CT angiogram and cerebral angiogram in acute ischemic stroke patients undergoing endovascular treatment. All acute ischemic stroke patients who underwent a CT angiogram and subsequently underwent endovascular treatment were included. The CT and cerebral angiographic images were reviewed independently to determine presence and location of arterial occlusion. Severity of occlusion was classified by a previously described grading scheme. Clinical outcome at discharge was determined using modified Rankin scale. Computed tomographic angiogram was performed in 150 patients (mean age ± SD, 64.7 ± 16 years) before endovascular treatment. The mean interval (±SD) between CT angiogram and cerebral angiogram was 193 ± 164 minutes, and 65 (43.3%) of 150 patients received intravenous recombinant tissue plasminogen activator before cerebral angiography. Recanalization between CT angiogram and cerebral angiography was seen in ...Continue Reading

Brain Ischemia

Brain ischemia is a condition in which there is insufficient blood flow to the brain to meet metabolic demand. Discover the latest research on brain ischemia here.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Acute Stroke

A stroke occurs when blood supply to the brain is interrupted depriving the brain of oxygen and nutrients. This feed focuses cerebrovascular accidents including ischemic and paralytic stroke.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
