目的 采用超声引导下瘤内注射凝血酶（UGTI）治疗医源性股动脉假性动脉瘤（IFAP）合并动静脉瘘。方法 冠状动脉介入诊治术后IFAP患者32例，其中9例合并动静脉瘘。所有患者均接受UGTI治疗，并于术后3、14和30 d定期进行超声复查。结果 31例患者一次治疗成功，1例失败转行外科手术治疗。31例患者术后随访，均无IFAP复发以及栓塞和过敏反应等并发症发生。结论 UGTI治疗IFAP具有较高的临床价值，对合并动静脉瘘者同样安全、有效。

Objective To investigate the clinical value of ultrasound-guided thrombin injection (UGTI) in the treatment of iatrogenic femoral artery pseudoaneurysms (IFAP) with femoral arteriovenous fistulas. Methods Thirty-two patients with IFAP after coronary artery intervention were selected, among whom 9 were complicated with femoral arteriovenous fistulas. All patients were treated with UGTI, and underwent ultrasound examinations 3 d, 14 d and 30 d after treatment. Results Successful treatment was achieved in 31 patients, while the other patient failed and subjected to surgery. No recurrence of IFAP and no complications were found during follow up in 31 cases. Conclusion UGTI has a high clinical value for the treatment of IFAP, and is a safe and effective therapy for those complicated with femoral arteriovenous fistulas.
