Abstract:
Perforator stroke(PS)is one of peri-procedural complications associated with stenting of intracranial arterial stenosis.A lot of perforator arteries are derived from intracranial arteries with difference from coronary arteries,because once the intracranial perforator arteries of crucial regions are occluded,may lead to fatal prognosis.Three hypothesis have been used to explain PS including snow-plowing,stent jailing effect and in-stent neointimal growth.In vivo models,investigators have already found these phenomenas.After much attention been paid on PS,authors have published a report covered with a large amount of cases in 2006. The author figured out that patients with perforator infarct adjacent to the stenotie segment(PIAS)under MRI beforehand would have higher chance occurring PS after stenting of intracranial stenosis.The patients with priority of PS easily are affected by the morphology,location,etiology,sites,the type and equipments.Many yet unsolved problems including the prevention would arouse us to go deeper into for the exploration of the mechanism.(J Intervent Radiol,2007,16:858-862)
