Cystic adventitial disease of the common femoral artery at a previous surgical dissection site.

ABSTRACT

Cystic adventitial disease (CAD) is a rare vascular disorder associated with nonatherosclerotic peripheral vessel disease and occurs when mucoid cysts in the adventitia compress the blood vessel. The underlying etiology and pathogenesis of CAD remain debatable as various theories have been suggested. This case is interesting because the cyst developed from the previous common femoral artery (CFA) dissection site. To our knowledge, this is the first report of CAD developed at a previous operation site. Thus, we report herein a case of CAD arising from a previous embolectomy dissection site in the CFA that was successfully treated with surgery.
