Abstract
IntroductionIsolated aneurysm of common femoral artery is a rare occurrence. They may mimic other common conditions like groin lymph nodes or groin hernia.Case presentationHere we present a case of 61-years-old Chinese gentleman who presented with a right groin lump, which was suspected to be groin hernia but turned out common femoral artery aneurysm. The aneurysm was surgically excised and a prosthetic vascular repair was done.ConclusionIsolated common femoral artery aneurysms are rare and can mimic groin hernias, so one must be careful. Color Doppler is the investigation of choice. Best treatment modality is surgical excision with repair with or without graft for aneurysms > 2.5 cm.
Highlights
Isolated aneurysm of common femoral artery is a rare occurrence
Femoral arterial aneurysms (FAAs) are uncommon aneurysms that are usually diagnosed as a pulsatile mass in the groin
Ultrasound (US) showed a 3.7 × 3.2 × 2.3 cm saccular aneurysm arising from the posterior aspect of the right common femoral artery (CFA) with thickened wall measuring 0.9 cm
Summary
Aneurysms can occur in almost any artery in the body, but the most common locations are in the abdominal aorta, thoracic aorta, cerebral vessels, and iliac, popliteal, and femoral arteries in descending order of frequency. Femoral arterial aneurysms (FAAs) are uncommon aneurysms that are usually diagnosed as a pulsatile mass in the groin They occur in elderly men, often with other manifestations of atherosclerosis. Isolated true femoral artery aneurysms are relatively rare and are found in elderly men with a strong history of smoking [1]. We present a case of isolated common femoral artery aneurysm. Ultrasound (US) showed a 3.7 × 3.2 × 2.3 cm saccular aneurysm arising from the posterior aspect of the right common femoral artery (CFA) with thickened wall measuring 0.9 cm. In their report acute dilatation and rupture occurred in 34.5% [4] This number emphasizes the need of a complete angiological investigation in patients with aneurysms [4]. There was intimal ulceration with cholesterol clefts and foamy histiocytes and plasma cell suggestive of athereosclerotic changes
