Adventitial cystic disease (ACD) is a rare condition that typically presents in young healthy men with symptoms of claudication. ACD is characterized by formation of a mucinous cyst within the adventitia of a blood vessel, usually in the popliteal artery, causing compression of the vessel’s lumen and leading to reduced flow and symptoms of claudication. We have presented a rare case of ACD of the common femoral artery in a young female patient that was treated successfully with resection and femoral vein graft interposition reconstruction.

We report the case of a 61-year-old man who had presented with acute unilateral limb swelling. Computed tomography venography and duplex ultrasound demonstrated compression of the right common femoral vein by a common femoral vein adventitial cyst. Before intervention, the patient had developed an acute deep vein thrombosis of the right common femoral vein and great saphenous vein. Preoperative magnetic resonance imaging demonstrated concern for synovial connection. After 6 months of anticoagulation therapy, the patient underwent adventitial cyst excision with ligation of the hip joint articular connection. At 4 months postoperatively, the patient was symptom free without cyst recurrence. The findings from the present case support the synovial theory for adventitial cystic disease.

Adventitial Cystic Disease (ACD) is a rare cause of peripheral arterial disease that accounts for less than 1% of all causes of claudication. It typically presents in younger individuals and surgical reconstruction is the mainstay of treatment. We report a case of a 60-year-old, active female with progressively worsening claudication, who presented with ultrasound and computed tomography angiography revealing ACD involving the common femoral artery. The patient underwent a complete resection of the affected artery, which was replaced with an interposition Dacron bypass graft. We also present a comprehensive review of literature on surgical management of ACD of the femoral artery.

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.

Adventitial cystic disease of the venous system is an extremely rare condition. Forty-five cases have been described in the literature during the last 70 years, but they may not be representative of the real incidence of this pathologic process. We report a case of an adventitial cyst compressing the right external iliac vein and presenting with edema of the ipsilateral leg. Ultrasound imaging and computed tomography angiography showed the typical features of cystic disease and venous stenosis. Cyst excision was performed with a double surgical access. No perioperative complications were reported. There was no recurrence at 4-year follow-up.

Adventitial cystic disease (ACD) is an unusual cystic tumor of blood vessels characterized by the accumulation of mucinous substance in the adventitia of the non-axial blood vessels adjacent to joints. Patients with ACD often suffer from intermittent claudication and/or limb pain, mostly involving the popliteal artery. We report a 30-year-old male who presented with intermittent claudication in his left leg. Angiography showed an obstructive lesion in the left popliteal artery. The lesion was treated successfully by surgical excision followed by graft vessel replacement. ACD involving the popliteal artery was diagnosed by pathologic findings of multiple cysts of the adventitia with external compression and focal narrowing of the vascular lumen. The cysts contained acid mucin and were partially lined by multiple rows of cytologically bland, synovium-like cells with positive immunoreactivity to vimentin and CD68 but negative immunoreactivity to cytokeratin. The histopathologic findings in this case suggest that it was caused by the developmental rests of mucin-secreting mesenchymal cells derived from the knee joint.
