Treatment of pseudoaneurysms has traditionally been surgical. We evaluated
12 patients who developed femoral artery pseudoaneurysms after cardiac
catheterization. Using color Doppler ultrasonography steady pressure was
applied, occluding flow in both the neck and body of the pseudoaneurysm for
10 minute intervals. Six patients were treated successfully. We believe the
same technique was unsuccessful in five additional patients because
compression of a short (< 5 mm) or wide neck is ineffective. In one
patient the pseudoaneurysm thrombosed spontaneously prior to a treatment
attempt. We believe compression ultrasonography of pseudoaneurysms should
be offered as a therapeutic alternative to surgery in selected cases.
