动脉瘤性蛛网膜下腔出血的CT分布规律及MSCTA动脉瘤分布对照分析

摘要

Objective To discover distribution relation between location of aneurysm and bleeding site of aneurysmal SAH by comparative analysis of CT of aneurysmal subarachnoid hemorrhage and MSCT.Methods Data of SAT and MSCTA of 30 SAT patients caused by aneurysm were retrospective analyzed. VR and MPR, Mip, VCR and other post-processing methods were adopted in CTA.Results 36 aneurysms were detected in MSCTA of 30 patients with aneurysmal SAH. In addition, SAT caused by aneurysm rupture in different locations would have different performances and its hemorrhage had certain laws in intracranial distribution.Conclusion There is a certain correlation between responsible aneurysm of aneurysmal SAH and intracranial distribution of SAH.%目的：通过对动脉瘤性蛛网膜下腔出血的CT及MSCTA的对照分析，发现动脉瘤发生部位与动脉瘤性SAH出血部位的分布关系。方法回顾性分析30例动脉瘤所致SAH患者的CT及MSCTA资料，CTA采用VR，MPR，Mip及VCR等后处理方法。结果30例动脉瘤性SAH中MSCTA检出36个动脉瘤，发现不同部位的动脉瘤破裂所引起的SAH在CT上可以有不同表现，其出血在颅内分布有一定的规律。结论动脉瘤性SAH的责任动脉瘤与SAH在颅内分布规律有一定的相关性。
