Mechanisms of Stroke in Intracranial Stenosis "MoSIS"

Terminated

Phase N/A Results N/A

Trial Description

The objective of this SAMMPRIS-affiliated study is to understand the mechanisms the mechanisms that underlie ischemic stroke recurrence in high-grade intracranial atherosclerotic disease in order to determine predictors of recurrent stroke. MoSIS will evaluate 6 specific mechanisms of stroke in the medically-treated SAMMPRIS cohort: decreased antegrade flow, progression of stenosis, decreased proximal collateral flow, decreased distal collateral flow, impaired cerebrovascular reserve, and artery-to-artery embolism.

Trial Stopped: The affiliated study SAMMPRIS (Stenting and Aggressive Medical Management for Preventing Recurrent stroke in Intracranial Stenosis) has stopped enrollment.
