Two Cases of Popliteal Cystic Adventitial Disease Treated With Excision and Primary Bypass Graft: A Review of the Literature

Adventitial cystic disease in the external iliac artery of a 29-year-old man

Adventitial cystic disease (ACD) is an uncommon condition that generally occurs at the popliteal artery but, rarely, can occur in the external iliac artery. To date, only eight cases of ACD occurring in the external iliac artery have been reported. We have reported the case of a 29-year-old man who had presented with new-onset claudication. Despite an extensive imaging workup, ACD was not confirmed until the gross intraoperative examination. We have reported our process of diagnosis and treatment in addition to that reported in previous studies to enhance the historical fund of knowledge for this rare pathology.
