Abstract:
Objective To observe the clinical characteristics of progressive stroke (PS) patients with vascular stenosis and the relationship between PS and cerebral blood flow (CBF). Methods Fifteen patients of PS with anterior circulation vascular stenosis were chosen, their clinical documents and CBF were analyzed with Xenon-CT when they were in progression. Results These patients mostly presented hemiparalysis and language dysfunction at the beginning ( 13/15 ) before the disease developed rapidly into a serious state. The infarction usually happens in the periventricular area (10/15). Upper limbs paralyzed more severely than low limbs(11/15). Cerebral hypoperfusion areas around the infarction in 11 patients ( 10 ml·100 g-1·min-1 < CBF < 20 ml·100 g-1·min-1 ) were found. Conclusions Patients of PS with vascular stenosis present typically clinical characteristics, Low CBF caused by cerebral artery stenosis may be one of the most important factors leading to PS.
