肱动脉穿刺术并发症的预防与处理

目的 总结经皮肱动脉穿刺术的临床经验,探讨相关并发症发生的原因及其预防及处理对策.方法 回顾性分析2001年6月至2009年6月因行血管腔内诊疗而接受超声引导下肱动脉穿刺术87例患者的临床资料,总结发生并发症情况及其发生原因.结果 87例患者在超声引导下行肱动脉穿刺术均成功,成功率为100%,其中超声引导下一次穿刺成功有53例(61%),经多次穿刺成功有34例(39%).16例患者(19例次)发生了并发症,并发症发生率为18.4%.其中导丝进入血管周围间隙4例(4.6%),穿刺局部发生血肿11例(12.6%),其中3例合并局部神经损伤(1例为迟发型神经损伤),假性动脉瘤1例(1.2%).结论 熟悉肱动脉穿刺术部位的解剖特点,掌握相应的操作技巧并对其并发症有足够的认识和处理对策的充分准备可以减少并发症及其不良后果的发生.

Prophylaxis and treatment for complications associated with catheterization of brachial artery

Objective To summarize our clinical experience of prophylaxis and treatment for complications associated with catheterization of brachial artery. Methods 87 patients underwent endovascular treatment via brachial artery. Complications associated with catheterization of brachial artery were retrospectively analyzed. Results Under ultrasonic guidance the catheterization procedure of brachial artery was successful in all 87 patients. The success rate of cannulation was 100%. In 53 patients(61% ) ultrasonic guided cannulation was successful at the first attempt, the other 35 (39% ) with 2 or more than 2 times puncture. Complications associated with catheterization of brachial artery were detected in 16 cases. The complication rate was 18. 4%. Guidewire insertion into peri vascular compartment took place in 4 cases (4. 6% ). Episodes of local hematomas were noted in 11 cases( 12. 6% ) and in three of the 11 cases nerve injuries were detected (one of which was of late-onset type). Brachial artery pseudoaneurysm was found in 1 case(1.2%). Conclusion Familiarity with the anatomical features of the brachial access, skillful application of the techniques for the catheterization, full understanding of complications and sufficient preparation of treatment strategies can prevent those complications effectively.
