Stenting for Symtomatic Intracranial Artery Stenosis Registry in China
Data Collection
Collected from today forward - ProspectiveCohort
Tracking disease incidence in order to identify risk factors and understand disease progression over time.Summary
Study start date: April 1, 2013
Actual date on which the first participant was enrolled.Stenting for systematic Intracranial artery stenosis is challenged recently, especially for safety. This registry is aimed to explore the safety profile during peri-operation period in Stenting procedures for systematic Intracranial artery stenosis in Chinese population in real world.
