Treatment failure after rotational atherectomy and balloon angioplasty in recurrent cystic adventitial disease of the popliteal artery: a case report

Abstract

Cystic adventitial disease (CAD), which usually affects the popliteal artery, is a rare vascular condition in which fluid accumulates in the sub-adventitial layer, compressing the lumen. Historically, surgical treatment is preferred over endovascular or minimally invasive techniques, due to its lower recurrence rates. Here, the case of a 67-year-old male patient, in whom rotational atherectomy was performed for recurrent CAD following surgical cyst excision and patch angioplasty is reported. The patient’s symptoms recurred one day after the rotational atherectomy procedure and repeat computed tomography angiography showed recurrence of the disease. Due to gradual worsening of the condition during 8 months of follow-up, left distal femoral artery to popliteal artery (below-the-knee) bypass surgery was performed using an ipsilateral reversed great saphenous vein graft. Follow-up has continued for 2 years without complications or requirement of additional treatment. This novel case is the first report of atherectomy attempted for recurrent CAD that led to an early recurrence. Our experience emphasises that additional surgical approaches should be selected over endovascular procedures for treating recurrent CAD. © The Author(s) 2022.
