中国台湾高雄长庚纪念医院吴炯仁等研究提示,经桡动脉利用指引导管在主动脉窦部反折顺向行颈部血管检查、治疗是方便、安全可行的。

该方法是作者在临床工作中遇到那些由于主动脉弓血管畸形经股动脉脑血管造影失败的案例,改为由桡动脉完成颈动脉血管检查及治疗的过程中发现的一种治疗方法,称为指引导管反折技术。

该研究中,33例患者成功经桡动脉路径完成颈部动脉血管造影检查,颈动脉狭窄>70%的患者16例,完成靶血管支架置入17枚。

6例患者术中出现暂时性窦性心动过缓,2例出现短暂性血压下降,予以对症治疗后好转,均无不良后果,未出现继发脑梗死、桡动脉闭塞等术后并发症。且术后患者能即刻行走自如。

研究者指出,指引导管反折技术的缺点为在导管在推送过程中因反折张力过大而容易掉入左心室,特别是有主动脉瓣反流的情况下,需要反复调整推送力度。

对于初学者不易掌握,学习曲线较长,此外对于横位心主动脉窦部起始处与主动脉弓有较大夹角的病例需要注意支点的选择,否则支架导管的推送会缺乏支撑力。

已经发表的结果显示指引导管反折技术的成功率可达99%,并发症较其他方法没有增加,特别是穿刺部位出血风险远远低于股动脉穿刺路径。
