Abstract:
Objective To evaluate the feasibility and safety of ultrasound-localized percutaneous thrombin injection (ULTI) for the treatment of iatrogenic femoral pseudoaneurysm. Methods From January 2000 through October 2001, 5 patients (3 males, 2 females, age range 38～72 years) were found to have a pseudoaneurysm confirmed by ultrasound between 1 and 3 days following femoral arterial puncture. Two patients were associated with diagnostic arteriography and 3 with stent implantation. ULTI was our first choice for the treatment of ablating femoral pseudoaneurysm. All patients following ULTI were restudied within 24 hours. Results All 5 patients were initially treated with ULTI. Thrombin was injected directly into the pseudoaneurysm with a dose of 500 units over several seconds, successful ablation was visualized immediately in 4 patients, the remaining 1 patient needed ultrasound-guided compression treatment of five minutes. Follow-up at the 24th hour showed no recurrent pseudoaneurysm after initial successful ablation in any case. No distal embolization or allergic reaction occurred. Conclusion ULTI is a safe, rapid, well-tolerated, inexpensive and effective noninvasive method for the treatment of iatrogenic femoral pseudoaneurysm and should be considered as first-line therapy.
