title: Cystic adventitial disease of the popliteal artery: Two case reports and a review of the literature.
abstract: Two cases of cystic adventitial disease treated at our institution over the last year are presented. They were middle-aged and apparently healthy patients, and the symptoms begin with a sudden onset of unilateral claudication. After performing a magnetic resonance angiography, a cystic formation attached to the adventitia of the popliteal artery was identified. Both patients were treated in the same manner, with resection of the affected arterial segment and vein bypass interposition. Both remain asymptomatic after one year of follow-up in one case and six months in the other. Cystic adventitial disease is a rare entity, which presents in patients without cardiovascular risk factors, so sometimes it takes long to reach a definitive diagnosis. Concerning the different treatment options, cyst excision together with the affected arterial segment seems to offer better mid- and long-term results when compared with other treatment options such as cyst aspiration or endovascular techniques, although there are no multicenter trials evidencing the superiority of one against the others.
