Intraprocedural predictors of post-stent retriever thrombectomy subarachnoid hemorrhage in middle cerebral artery stroke.

Background: Stent retriever thrombectomy (SRT) in acute thromboembolic stroke can result in post-thrombectomy subarachnoid hemorrhage (PTSAH). Intraprocedural findings associated with PTSAH are not well defined.

Objective: To identify angiographic findings and procedural factors during SRT that are associated with PTSAH.

External carotid artery stenting to treat patients with symptomatic ipsilateral internal carotid artery occlusion: a multicenter case series.

Background: The external carotid artery (ECA) anastomoses in many distal territories supplied by the internal carotid artery (ICA) and is an important source of collateral circulation to the brain. Stenosis of the ECA in ipsilateral ICA occlusion can produce ischemic sequelae.

Objective: To examine the effectiveness of ECA stenting in treating symptomatic ipsilateral ICA occlusion.
