先天性血管变异患者脑血管造影安全性研究

Safety of cerebral catheter angiography in patients with congenital vascular variation

目的了解先天性血管变异患者行脑血管造影检查的安全性。方法收集297例单纯脑血管造影患者,按照是否存在先天性血管变异将其分为对照组(288例,无先天性血管变异)与血管变异组(9例),对其造影并发症的发生及诱因进行回顾性分析。结果血管变异组造影并发症的发生率为33.3%,对照组为2.1%,2组比较差异有统计学意义(P<0.01)。操作不当是引起对照组并发症的主要原因;与此不同的是,引起血管变异组并发症的主要原因在于血管变异本身。结论存在先天性血管变异的患者行脑血管造影的风险较大,应首选其他无创血管影像检查。

Objective To evaluate the safety of cerebral catheter angiography in patients with congenital vascular variation. Methods Two hundred and ninety-seven patients with simple cerebral angiography procedures were divided into the control group （288 cases） and the vascular variation group （9 cases）, depending on whether or not there was congenital vascular variation in them. Then, incidence and causes of vascular angiographic complication in the 2 groups were compared and analyzed. Results Rates of com plication in the vascular variation group and the control group were 33.3% and 2.1% respectively, indicating that there was statistical difference between them （P 〈 0.01 ）. Malmanipulation was the main reason for the incidence of complication in the control group, while the chief cause of complication in the vascular variation group was due to vascular variation. Conclusion The risk of complications for patients with congenital vascular variation was obviously greater, for this reason, non-invasive angiography such as MRA or CTA should be the first choice for these patients.
