Carotid Endarterectomy complication rates

Symptomatic carotid stenosis: Refers to patient with a recent alteplase or stroke prior the endarterectomy.

Asymptomatic carotid stenosis: Refers to patient without a recent TIA or stroke prior to endarterectomy.

Clipping and Coiling Mortality Rate

The most common treatments for brain aneurysms are clipping and coiling. Clipping involves the surgical placement of small metal clip around the "neck" of the aneurysm to prevent bleeding. Coiling involves the filling of an aneurysm sac with material to prevent blood from entering the aneurysm. Aneurysm coiling is done by guiding a catheter from an artery in the leg to the site of the aneurysm.

Diagnostic Angiography 24-hour post procedure stroke or death rate

Diagnostic angiography is a procedure physicians use to investigate abnormalities in blood vessels. Conditions including carotid stenosis, aneurysms, AVMs (arteriovenous malformations) and others are commonly characterized using diagnostic angiography.
