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 investigate the clinical and imaging features of vertebrobasilar cerebral infarction. Methods: The clinical data of 33 patients with vertebrobasilar cerebral infarction were retrospectively analyzed. 1 routine CT examination, 32 cases of cranial magnetic resonance imaging (MRI). Two patients underwent CTA, two MRA and four DSA. Results: 16 cases of typical vertebrobasilar cerebral infarction patients (48.48%). The lesions were detected by MRI. Most of the newly diagnosed lesions were pontine infarction, with 12 cases (36.4%), 4 cases (12.1%) with midbrain and 6 cases (18.2%) with medulla oblongata and cerebellum. Conclusion: Cerebral infarction of vertebrobasilar artery is the most common type of cerebral infarction with complicated clinical symptoms. MRI has a high detection rate of cerebral infarction in vertebrobasilar artery system. Vascular imaging can further identify the diseased vessels. Therefore, Patients with infarction and early MRI and angiography (MRA, CTA, DSA) to guide the clinical treatment and evaluation of prognosis.
