Purpose:
During the past 14 months we conducted a prospective clinical trial to evaluate the efficacy of duplex-directed manual occlusion (DDMO) of iatrogenic femoral false aneurysms (FFAs) as an alternative to standard operative management.
Methods:
In all cases DDMO was performed with real-time color-flow imaging while steady, continuous external pressure was applied manually to the neck of the FFA by an experienced vascular technologist for a period of 10 minutes.
Results:
Ten of the 11 FFAs treated with DDMO in this series were thrombosed successfully, requiring a mean of 30 minutes of compression per aneurysm (three compressions of 10 minutes each). DDMO was unsuccessful in one patient, whose session was terminated because of severe discomfort as a result of the procedure. All 10 patients with successfully thrombosed FFAs are without recurrence at 1-month follow-up color-flow duplex examination, and there has been no morbidity attributable to DDMO.
Conclusions:
We conclude that DDMO of postcatheterization FFA can be performed safely and is an inexpensive, effective, nonoperative method of managing such lesions. The precise role of this technique would appear to be as a first-line treatment for uncomplicated iatrogenic FFAs.
