| 摘 要： | 目的探讨后循环缺血患者脑血管病变的特点。方法对74例后循环缺血患者进行CT血管成像(CTA)检查,分析血管病变的部位、性质和程度。结果本组74例后循环缺血患者中61例(82.4%)被CTA证实有血管病变。其中,血管动脉粥样硬化病变8例(10.8%),血管狭窄38例(51.4%),血管纤细22例(29.7%),血管发育不良12例(16.2%)。单纯前循环血管病变7例(9.5%),单纯后循环血管病变21例(28.4%),前后循环均有血管病变例33例(44.6%);前循环血管病变以颈内动脉颅外段狭窄为主,后循环血管病变以椎动脉颅外段和大脑后动脉病变最为多见;前、后循环血管病变狭窄程度均以重度为主。结论后循环缺血患者的主要血管病变部位在椎动脉颅外段和大脑后动脉,其次为颈内动脉颅外段;最常见的病变性质是动脉粥样硬化和血管狭窄,且以重度狭窄最为多见。 |

| Abstract: | Objective To investigate the features of cerebrovascular lesions in patients with posterior circulation ischemia(PCI).Methods CT angiography(CTA) was detected in 74 PCI patients,and the location,nature and extent of the vascular lesions were analyzed.Results There were 61 cases(82.4%) with vascular disease proved by CTA.In which,the vascular atherosclerosis were 8 cases(10.8%),the vascular stenosis were 38 cases(51.4%),the vascular slender were 22 cases(29.7%) and the vascular dysplasia were 12 cases(16.2%)... |
