Which of the following statements about false aneurysms of the femoral artery is/are correct?

A. The incidence of iatrogenic false aneurysms has increased in recent years.

C. Ultrasound-guided compression of iatrogenic false aneurysms is usually successful in achieving thrombosis.

DISCUSSION: With the introduction of invasive percutaneous procedures such as angioplasty, valvuloplasty, atherectomy and coronary stenting, the incidence of iatrogenic false aneurysms has risen to about 0.6% to 1.0% in recent years. Colorflow duplex ultrasound is the best test for diagnosis of these aneurysms, owing to its ability accurately to delineate the anatomy. Additionally, compression of these false aneurysms using ultrasound guidance is very effective in achieving thrombosis. Femoral anastomotic aneurysms are most commonly seen after aortofemoral bypass grafting and only rarely are associated with infrainguinal procedures. Thromboembolic complications are the most common complication of these lesions.
