Abstract
Introduction:
Iatrogenic femoral artery pseudoaneurysm (FAP) is a complication following femoral artery puncture, with an incidence rate of 0.2%–5.5% post-cardiac catheterization procedures. Management typically involves observation or interventional treatments such as ultrasound-guided compression (UGC) or ultrasound-guided thrombin injections. This study compares the efficacy and safety of ultrasound-guided autologous blood clot injection (UGCI) with C-clamp vascular closure device-assisted UGC in treating FAP.
Materials and methods:
Conducted at a high-volume training and research center, this prospective study enrolled patients with iatrogenic FAP post-femoral artery puncture. Patients were randomized into two treatments: UGC with a C-clamp device or UGCI. Primary endpoints were thrombosis induction within 24 h, average procedure time, and length of hospital stay (LOS).
Results:
The study included 105 patients with 51 undergoing UGCI and 54 undergoing UGC. UGCI achieved a primary success rate of 96% versus 63% for UGC. The mean procedure duration for UGCI was significantly shorter (22 min) compared with UGC (49 min, p ⩽ 0.0001). LOS was also reduced in the UGCI group (1.5 days) compared to the UGC group (4.5 days). Complication rates were low for both procedures, with one deep vein thrombosis and one infection observed in the UGC group.
Conclusion:
UGCI demonstrated to be a safe, efficient, and faster alternative for treating iatrogenic FAPs with a higher success rate, reduced LOS, and similar low complication rates compared to UGC. This study suggests that UGCI could be considered a preferred method for the management of FAP post-femoral artery catheterization.
