Postangiographic femoral artery injuries: nonsurgical repair with US-guided compression.

Ultrasound-guided compression repair (UGCR) of catheterization-related femoral artery injuries was evaluated as a possible new imaging-guided interventional procedure. Thirty-nine femoral artery injuries (35 pseudoaneurysms, four arteriovenous fistulas) were detected with color Doppler flow imaging in patients with enlarging groin hematomas and/or groin bruits 6 hours to 14 days after catheterization procedures. UGCR was not performed in 10 patients due to spontaneous thrombosis (n = 4), infection (n = 1) or skin ischemia (n = 1), unsuitable anatomy (n = 3), or excessive discomfort (n = 1). The remaining 29 patients underwent a full trial of compression therapy, and the lesion was eliminated in 27. Follow-up color flow scans were obtained after 24-72 hours in all 27 successful cases and at 1-15 months in 19; no recurrences or complications occurred. UGCR for acute injuries is safe and technically simple and is promising as a cost-effective, first-line treatment for uncomplicated catheterization-related femoral artery injuries. UGCR is probably not appropriate for long-standing injuries.
