目的探讨冠心病介入治疗术后迟发型假性动脉瘤的特点与治疗。方法回顾性分析11例冠心病介入治疗术后迟发型假性动脉瘤临床资料。结果 11例假性动脉瘤发生在术后24-72h,75岁以上和女性患者占多数。术后应用低分子肝素也有促进迟发型假性动脉瘤发生的趋势。注射凝血酶200-500U后,超声监测示瘤腔回声明显增强,瘤腔内血流信号消失。结论冠心病介入手术后迟发型假性动脉瘤不容忽视,尤其是老年女性与低分子肝素应用的患者;超声引导下的凝血酶注射是有效的治疗手段。
Objective To investigate the characteristics and treatment of delayed pseudoaneurysm after coronary intervention. Methods The clinical data of 11 patients with delayed type pseudoaneurysm after coronary intervention were analyzed retrospectively. Results 11 cases of pseudoaneurysm occurred in 24-72h postoperatively, with over 75 years old and female majority. Postoperative application of low molecular weight heparin can also promote delayed pseudoaneurysm. After injection of thrombin 200-500U, ultrasound monitoring showed significantly enhanced tumor cavity echo, tumor cavity blood flow signal disappeared. Conclusions Delayed pseudoaneurysm should not be neglected after coronary intervention, especially for elderly women and low molecular weight heparin. Thrombin injection guided by ultrasound is an effective treatment.
