椎基底动脉系统脑梗死临床及影像学分析

Analysis of clinical manifestations and cerebral angiography of 33 patients with vertebrobasilar artery infarction

目的:探讨椎基底动脉系统脑梗死的临床及影像学特点。方法:对33例椎基底动脉系统脑梗死患者的临床资料进行回顾性分析。1例行CT检查,32例行头颅核磁共振(MRI)检查。2例行CT血管成像检查(CTA),2例行磁共振血管成像检查(MRA),4例行脑血管数字减影(DSA)检查。结果:典型椎基底动脉系统脑梗死患者16例(48.48%)。MRI检查均发现相应病灶,新发病灶以桥脑梗死最多见,共12例,占36.4%,中脑4例(12.1%),延髓与小脑均为6例(18.2%)。结论:椎基底动脉系统脑梗死以桥脑梗死为最多见,临床症状复杂,MRI检查对椎基底动脉系统脑梗死检出率较高,血管成像可进一步明确病变血管,故对椎基底动脉系统脑梗死患者及早行MRI及血管成像(MRA、CTA、DSA)以指导临床治疗和评价预后。

Objective： To discuss the clinical features and imagings of the vertebrobasilar artery infarction. Methods： Thirty-three patients were reported. Clinical manifestation, imaging findings including the com- puter tomography （CT）, magnetic resonance （MR） and digital substruction angiography （DSA） were ana- lyzed. Results： The classic symptom of vertebrobasilar artery infarction was 16 patients （48.48~）. Of all the 33 patients ,32 cases were diagnosed by MRI. Conclusions： MRI and cerebral angiography should be applied as early as possible to located the occlusion blood vessel so as to guide the treatment and evaluate the outcome.
