【摘要】：目的探讨椎动脉发育异常伴胚胎型大脑后动脉(FTP)与后循环缺血(PCI)之间的关系。方法回顾性分析接受头颅容积CT数字减影血管成像(VCTDSA)检查的218例PCI患者(PCI组)和110名无前后循环缺血临床表现的健康志愿者(对照组)。于VR图上观察有无孤立性椎动脉(IVH)、椎动脉发育不良(HVA)及FTP,并测量双侧椎动脉颅内段起始处管径。对椎动脉发育异常合并FTP与PCI进行相关性分析。结果 1对照组中,IVH占1.82%(2/110),HVA占17.27%(19/110),FTP占7.27%(8/110);其中椎动脉发育异常伴FTP占0.91%(1/110);2PCI组中,IVH占10.55%(23/218),HVA占49.08%(107/218);FTP占28.90%(63/218);椎动脉发育异常伴FTP占25.23%(55/218);3对照组与PCI组间椎动脉发育异常伴FTP的检出率差异有统计学意义(2χ=35.56,P0.001);4椎动脉发育异常伴FTP与PCI具有相关性(r=0.31,P0.001)。结论椎动脉发育异常伴FTP可能引起PCI。
[Abstract]:Objective to investigate the relationship between posterior cerebral artery (FTP) and posterior circulation ischemia (PCI) in patients with dysplasia of vertebral artery and embryonic posterior cerebral artery. Methods A retrospective analysis of 218 PCI patients with VCTDSA and 110 healthy volunteers without anterior and posterior circulation ischemia (control group) was performed. The IVH, HVA and FTP of isolated vertebral artery were observed on VR images, and the diameter of intracranial segment of bilateral vertebral artery was measured. Correlation analysis of vertebral artery dysplasia combined with FTP and PCI was carried out. Results (1) in the control group, IVH accounted for 1.82% of HVA, 17.27% was 19 / 110%, FTP was 7.27%, and vertebral artery dysplasia with FTP 0.91% was 0.91%. The ratio of IVH to 10.55% was 10.55%. 23% 21818 HVA was 49.08% 107218% FTP was 28.906.63% 21818; the rate of abnormal development of vertebral artery was 25.2355% 2183% in the control group and 25.2355% -2183% in the PCI group, and the difference in the detection rate between the control group and the PCI group was 25.2355% 2183%. There was statistically significant difference in vertebral artery dysplasia (P 0.001) with correlation between FTP and PCI (P 0.001). Conclusion abnormal development of vertebral artery with FTP may cause PCI.
