Ultrasound-guided injection of thrombin is the treatment of choice for femoral pseudoaneurysms.
A prospective study of patients undergoing a single form of treatment for femoral pseudoaneurysms.
Patients were treated at 2 tertiary care, university-affiliated hospitals.
Forty consecutive patients with femoral pseudoaneurysms resulting from diagnostic and therapeutic catheterizations for peripheral arterial, coronary arterial, and cerebrovascular diseases were evaluated.
Thrombin was injected directly into the pseudoaneurysms under ultrasonographic guidance.
Main Outcome Measure
Thrombosis of the pseudoaneurysm following thrombin injection was the goal of treatment.
All 40 patients had initial complete thrombosis of their femoral pseudoaneurysms. In each case, except for one, the aneurysm was noted to have thrombosed on follow-up duplex ultrasongram. There was one complication.
Ultrasound-guided thrombin injection is the treatment of choice for femoral pseudoaneurysms.
