An unexpected intraoperative finding of cystic adventitial degeneration of the common femoral artery

Description

Herein we present a rare case of cystic adventitial degeneration involving the common femoral artery (CFA) of a 71-year-old patient, an unusual site of presentation of the disease. The most commonly affected district is the popliteal artery, and only a few cases of CFA involvement are described in literature. The history and comorbidities of the patient oriented us initially towards the diagnosis of an atherosclerotic obstructive disease. It was only intraoperatively indeed that a diagnosis of cystic adventitial arterial degeneration was made, subsequently confirmed by microscopic examination. Our case shows how both clinical and instrumental diagnosis of cystic adventitial disease can be challenging, given its non-specific presentation and low incidence. Suspicion of cystic adventitial degeneration is recommended in patients with sudden appearance of symptoms and with an isolated lesion of the affected artery without other involvement of the vascular tree.
