Ultrasound‐guided thrombin injection in the treatment of iatrogenic arterial pseudoaneurysms: Single‐center experience

The aim of this study was to assess the safety and efficacy of ultrasound‐guided percutaneous thrombin injection for the treatment of postcatheterization arterial pseudoaneurysms. We evaluated retrospectively 82 consecutive subjects treated with percutaneous ultrasound‐guided thrombin injection of postcatheterization femoral (n = 79), brachial (n = 2), and radial (n = 1) pseudoaneurysms from January 2006 to April 2012. Pseudoaneurysm size, thrombin dose, and therapy outcome were documented. All pseudoaneurysm sacs were thrombosed with a single injection. The overall primary success rate (complete sac thrombosis) was 92.7%. A 30‐day Doppler ultrasound follow‐up showed a 100% procedural success. There were no complications. © 2013 Wiley Periodicals, Inc. J Clin Ultrasound 42 :24–26, 2014     

Compression repair of ruptured pseudoaneurysms guided by color Doppler ultrasonography: report of two cases.

Noninvasive treatment of ruptured postcatheterization pseudoaneurysms is rare. We report the use of ultrasonographically guided compression repair for the treatment of ruptured pseudoaneurysms in 2 cases. To ensure the immediate stop of bleeding, more compression was applied than for nonruptured pseudoaneurysms, regardless of flow in the femoral artery or vein, thus maximizing the effectiveness of this therapy. With this method, complete thrombosis of the pseudoaneurysm could be achieved in less than 30 minutes. In both cases, ultrasonographically guided compression repair was faster than the time needed to prepare an operating room for surgical treatment. In follow-up examinations, no recurrences or further complications were detected. Ultrasonographically guided compression repair can be used for noninvasive treatment of ruptured pseudoaneurysms in some cases, provided that more compression than indicated for nonruptured pseudoaneurysms is applied. Further clinical experience with more patients will be necessary to determine the exact benefits and possible limitations.     

Percutaneous ultrasonographically guided thrombin injection of iatrogenic pseudoaneurysms in unusual sites.

OBJECTIVES: To evaluate the effectiveness and safety of percutaneous ultrasonographically guided thrombin injection as treatment of unusually positioned and unusually large iatrogenic pseudoaneurysms. METHODS: Five patients with iatrogenic pseudoaneurysms were evaluated by color duplex ultrasonography. Two patients had additional digital angiography, and 2 had additional computed tomographic angiography. In 3 of the patients, large, painful iatrogenic pseudoaneurysms located proximal (2 patients) and distal (1 patient) to the arteriovenous hemodialysis fistulas had developed, most likely due to erroneous puncture of the arterial side (brachial artery) or venous side (cephalic vein) of the fistulas. An iatrogenic pseudoaneurysm of the anterior tibial artery had developed in the fourth patient after osteotomy of the fibula, and an iatrogenic pseudoaneurysm of the superficial femoral artery had developed in the fifth patient after erroneous puncture during venous transfemoral angiography. With a sterile technique and color duplex ultrasonographic guidance, a diluted solution of bovine thrombin was slowly injected directly into the iatrogenic pseudoaneurysms until cessation of blood flow was seen. Follow-up color duplex ultrasonography was performed 24 to 48 hours after the ultrasonographically guided thrombin injection. RESULTS: Four iatrogenic pseudoaneurysms were successfully thrombosed during 1 session. Two large iatrogenic pseudoaneurysms necessitated multiple repositions of the injecting needle and several injections of small amounts of thrombin into the residual patent lumen to induce complete thrombosis without an appreciable increase in the total thrombin dosage. Follow-up examinations revealed complete and persistent thrombosis without evidence of distal embolization. One iatrogenic pseudoaneurysm involving the cephalic vein, distal to an arteriovenous hemodialysis fistula, recurred after apparently successful initial thrombosis. CONCLUSIONS: Most iatrogenic pseudoaneurysms are amenable to ultrasonographically guided thrombin injection as long as they are imaged adequately by color duplex ultrasonography.
