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.
