为明确近头端基底动脉区这一特殊部位血管闭塞性疾病的范围及特点，对３４例此区域梗塞的临床表现及影像学进行了分析。全部患者均做了ＣＴ，同时做磁共振成像（ＭＲＩ）的有２３例，做脑血管检查的有１２例。此区范围包括大脑后动脉、近头端基底动脉及小脑上动脉供血区。临床常表现为多部位梗塞，可分为大脑后动脉皮层支（２１例），大脑后动脉中央支（２２例）及小脑上动脉（１０例）三组。提示该区病变ＭＲＩ确定梗塞部位优于ＣＴ，但找出血管闭塞部位目前尚有困难，可结合使用脑血管数字减影、磁共振血管造影及经颅多普勒超声协助诊断。
In order to clarify the scope and characteristics of proximal occlusive basal artery region, a special part of vascular occlusive disease, the clinical manifestations and imaging of 34 cases of infarction in this region were analyzed. All patients underwent CT, magnetic resonance imaging (MRI) in 23 cases and cerebral vascular examination in 12 cases. This area includes the posterior cerebral artery, proximal basilar artery and superior cerebellar artery. Clinical manifestations of multi-site infarction, can be divided into cerebral cortex branch (21 cases), the central branch of the posterior cerebral artery (22 cases) and the superior cerebellar artery (10 cases) three groups. It is suggested that the infarction location is better than CT in the lesion MRI in this area. However, it is still difficult to find out the occlusion sites of the blood vessels. It can be used in combination with digital subtraction of cerebrovascular, magnetic resonance angiography and transcranial Doppler ultrasound.
