Abstract
Isolated true aneurysms of the superficial femoral artery (SFA) are rare, accounting for 0.5% of peripheral aneurysms. The literature up to 2012 contains reports of just 103 patients with isolated SFA aneurysms. The main complications are thrombosis, distal embolization, and rupture, which is the most common of the three. The authors report the case of a 55-year-old male patient admitted to the emergency service with pain and a pulsatile mass in the left thigh, subsequently confirmed as rupture of an SFA aneurysm. The patient underwent open aneurysm repair with ligature and revascularization with a reversed saphenous vein bypass.
Highlights
True aneurysms of the femoral arteries generally involve the common femoral artery (CFA) or present as a proximal continuation of aneurysmal disease of the popliteal artery
Complications associated with superficial femoral artery (SFA) aneurysms include thrombosis, distal embolization, and rupture, the last of which is the most frequent
They are associated with lower rates of complications than other peripheral aneurysms, such as popliteal artery aneurysms, SFA aneurysms should be diagnosed and electively repaired in order to prevent complications.[2,4,5]
Summary
True aneurysms of the femoral arteries generally involve the common femoral artery (CFA) or present as a proximal continuation of aneurysmal disease of the popliteal artery. Pseudoaneurysms of the femoral arteries, which have become more frequent because of greater use of percutaneous procedures, are most common in the CFA. Complications associated with SFA aneurysms include thrombosis, distal embolization, and rupture, the last of which is the most frequent. They are associated with lower rates of complications than other peripheral aneurysms, such as popliteal artery aneurysms, SFA aneurysms should be diagnosed and electively repaired in order to prevent complications.[2,4,5]
