CLINICALLY GUIDED CLOSURE OF FEMORAL ARTERIAL PSEUDOANEURYSMS COMPLICATING CARDIAC-CATHETERIZATION AND CORONARY ANGIOPLASTY

Femoral artery pseudoaneurysm formation is a significant problem in patients undergoing cardiac catheterization and interventional cardiac procedures. It is especially more common with the use of anticoagulant and antiplatelet therapy and the use of intracoronary stents. We describe our initial experience with clinically guided.bedside compression of femoral pseudoaneurysms in such patients. Eleven patients, 10 undergoing coronary angioplasty (including 3 with intracoronary stents) and 1 undergoing diagnostic cardiac catheterization, developed a femoral pseudoaneurysm. All patients had a femoral bruit and 9 had an expansile groin hematoma. The diagnosis was confirmed in each case by Doppler ultrasound. Seven patients were receiving heparin while 4 were on oral anticoagulants at the time of detection of the pseudoaneurysm. These patients underwent clinically guided graded external compression to close the pseudoaneurysm neck while maintaining femoral arterial flow. External compression for 104.1 +/- 63 min resulted in successful clinical resolution of pseudoaneurysm in all patients without complications. The results were confirmed by Doppler ultrasound at least 12 hr later. Bedside compression of femoral pseudoaneurysms guided by clinical clues is simple and appears to be an effective and safe technique to manage this iatrogenic problem. (C) 1993 Wiley-Liss, Inc.
