经桡动脉穿刺全脑血管造影的可行性和安全性

目的探讨经桡动脉途径穿刺、行全脑血管造影的操作流程和手术技巧,分析该技术的安全性和可行性。方法选择明确有颅内外动脉中重度狭窄或闭塞的530例脑血管病患者,将年龄≥60岁216例作为老年组,年龄<60岁314例作为非老年组,均实施经桡动脉穿刺的全脑血管造影术,分析手术成功率、并发症;比较2组患者不同手术入径和材料的差异。结果 530例患者中,516例患者完成脑血管造影手术,手术成功率97.36%,老年组成功207例,非老年组成功309例。降主动脉成袢、主动脉瓣辅助降主动脉成袢的造影时间和受线时间均少于主动脉瓣成袢(P<0.05);Simmons 2型导管的造影时间和受线时间少于Simmons 3型导管(t=10.74,P=0.02);老年组与非老年组3种不同成袢技术的造影时间和受线时间比较,差异无统计学意义(P>0.05);2组桡动脉闭塞比例比较,差异有统计学意义(P<0.05)。结论经桡动脉途径行全脑血管造影操作安全可行,技术成功率高、并发症少。降主动脉成袢和主动脉瓣辅助降主动脉成袢的成功率更高,Simmons 2型导管优于Simmons 3型导管。

Feasibility and safety of transradial cerebral angiography

Objective To analyze the feasibility and safety of transradial cerebral angiography. Methods Five hundred and thirty patients with moderate-severe intracranial and extracranial artery stenosis or occlusion were divided into ≥60year old group(n=216)and <60years old group(n=314).The patients underwent transradial cerebral angiography.Its success rate and complications were analyzed and its approaches and materials were compared.Results The success rate of transradial cerebral angiography was 97.36%in 516patients(207in≥60years old group and 309in<60years old group).The time of angiography was shorter for descending aorta-assisted and aorta-assisted loop formation than for aortic valve-assisted loop formation(P< 0.05),and for Simmons type 2catheter than for Simmons type 3catheter(t=10.74,P=0.02). No significant difference was found in the 3angiographies between the two groups(P>0.05). The difference was significant in angiography for radial artery occlusion between the two groups(P<0.05).Conclusion Transradial cerebral angiography,especially for descending aorta-assisted and aortic valve-assisted loop formation,is safe with a high success rate and few complications, and is better for Simmons type 2catheter than for Simmons type 3catheter.
