A new interventional procedure in the treatment of iatrogenic pseudoaneurysm.
OBJECTIVE
The incidence of iatrogenic pseudoaneurysms as a complication of angiographic procedures is increasing. The purpose of this study was to test the validity and the efficacy of a new interventional procedure in the treatment of iatrogenic pseudoaneurysms.


METHODS
Between April 1999 and June 2000, 14 patients suffering from a iatrogenic pseudoaneurysm were treated with the new technique which consists of the direct puncture of the aneurysmal cavity using the Seldinger technique and the introduction of a movable-core Teflon-coated guide wire into the hollow of the sac. Mild external compression with Femostop is then applied for no longer than 120 minutes. The puncture was also performed with colour-Doppler US guidance.


RESULTS
We observed the complete healing of the pseudoaneurysms in all of the treated patients with no immediate complications or recurrence in the follow-up period.


CONCLUSIONS
The procedure applied to treat our group of patients proved valid, easy to perform and capable of producing satisfactory


RESULTS
This new interventional method for treating iatrogenic pseudoaneurysms may be considered an effective alternative to surgery and US-guided compression and capable of achieving a quick recovery. The procedure is particularly suitable in those patients that may suffer discomfort or complications from the widely applied technique of sonographically-guided compression of pseudoaneurysms.
