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., (© 2022 The Authors.)

Introduction and Importance: Adventitial Cystic Disease (ACD) is a vastly rare non-atherosclerotic vascular pathology that is principally manifested as intermittent claudication because of peripheral vascular ischemia. Precise etiological factors are not yet concretely identified, and it represents 0.1 % of all lower limb claudication causes. Middle-aged males are the most affected gender age group. Misdiagnosis of Popliteal Artery ACD could delay proper management and hence risk the loss of the affected limb due to critical limb ischemia., Case Presentation: We hereby explore the rare case of a 51-year-old female patient, who complained of vague left lower extremity pain accompanied by paresthesia for 1 month prior to admission without signs of local inflammation. The preoperative radiological assessment suggested the presence of thrombosis within the left Popliteal Artery which caused an occlusion in it and hence the proper blood flow was compromised., Clinical Discussion: Surgical intervention and the complete removal of the lesion along with establishing a patent synthetic anastomotic graft to maintain the preexisting vascular bundle was the key to treating our patient. Microscopic analysis of the excised specimen revealed an Adventitial Cystic Disease of the Popliteal Artery., Conclusion: Adventitial Cystic Disease represents an extremely rare vascular pathology with a vast margin of non-specific symptoms that could lead to misdiagnoses. It is fundamental to establish suitable preoperative screening protocols for it and sustain adequate levels of clinical awareness so that we can timely diagnose and in turn, achieve proper therapeutic interventions to plummet the potential disastrous complications that could ensue., Competing Interests: Conflict of interest The authors declare that they have no competing interests., (Copyright © 2022 The Authors.

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., (© 2021 The Authors.)

Adventitial cystic disease (ACD) of the veins is a rare vascular disease. Most cases of venous ACD are located adjacent to the joint area, such as the common femoral, external iliac, and popliteal veins. To the best of our knowledge, 67 cases of venous ACD have been reported, and ACD of the superficial femoral vein (SFV) has never been reported. Herein, we report the case of a 57-year-old male who presented with swelling and discomfort in the left leg. Computed tomography venography revealed multiple cystic lesions in the left distal SFV. The patient underwent cyst excision, which relieved the compression in the vein, although mild stenosis prevailed in the SFV. After a week, thrombosis developed in the popliteal vein. The thrombosis resolved after three months of anticoagulant therapy, and the patient showed no recurrence of ACD during three years of follow-up.

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., (© 2021 The Author(s).)

Objectives: Cystic adventitial disease is an extremely rare vascular disorder and is often misdiagnosed. In order to improve the knowledge and treatment of this disease, a case of venous cystic adventitial disease was reported., Methods: The whole processes about the diagnosis and treatment of one patient with venous cystic adventitial disease was retrospectively studied., Results: This case of venous cystic adventitial disease was diagnosed accurately by contrast-enhanced computed tomography and treated successfully by surgical resection. No complications were detected after one-year post-operative follow-up., Conclusions: Surgical resection is a safe and effective method for the treatment of venous CAD.

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., (© 2020 The Author(s).)

Adventitial cystic disease (ACD) is a vascular disorder most commonly affecting the popliteal artery. ACD is an uncommon and often misdiagnosed cause of lower extremity intermittent claudication that is usually acute in onset and of longer duration than claudication associated with atherosclerosis. We present two cases of ACD affecting the popliteal artery.

We report the case of a 68-year-old man with right intermittent claudication by adventitial cystic disease. We performed resection of the cyst and affected popliteal artery with interposing an autologous vein graft. Intraoperative findings revealed an intimal tear between the cyst and the compressed artery. His symptoms resolved after surgery, and the postoperative course was uneventful. Although adventitial cystic disease with intimal tear is rare, we consider that conventional surgical intervention remains the favorable treatment option for adventitial cystic disease. < Learning objective: We present a rare case of adventitial cystic disease (ACD) with intimal tear successfully treated with surgical repair. In the present case, intimal tear could not be detected preoperatively. Although this case is rare, we should pay attention to intimal tear in treating ACD. In case of ACD with intimal tear, resection of the affected artery and reconstruction with interposing graft are feasible.>.

Adventitial cystic disease (ACD) of the radial artery is a rare condition, with few cases described in the literature. We report the case of a 62-year-old white male with a history of diabetes, hypertension, and chronic kidney disease with indications for renal replacement therapy who was found to have a cystic lesion of the radial artery while undergoing surgical creation of an arteriovenous fistula. The surgical technique adopted was resection of the cystic segment and preservation of the radial artery. Fistula creation was completed successfully. Early diagnosis and appropriate treatment of ACD are effective, and can prevent complications and recurrence., Competing Interests: Conflicts of interest: No conflicts of interest declared concerning the publication of this article.

Adventitial cystic disease is a rare non-atherosclerotic vascular disease. We report a 36-year-old man with right intermittent claudication by adventitial cystic disease. computed tomography (CT) and magnetic resonance imaging (MRI) revealed an ovoid cystic mass compressing the right popliteal artery and causing severe stenosis of the lumen. Percutaneous aspiration was performed, which improved his symptoms. However, he complained of identical intermittent claudication two weeks later. Radiographic findings revealed that the cystic lesion had progressed rapidly. The cystic lesion was resected and the affected arterial segment was interposed. We consider that conventional surgical intervention remains the favored treatment option in the management of adventitial cystic disease.

Arterial adventitial cystic disease is an uncommon type of non-atherosclerotic peripheral vessel disease. Most cases of arterial adventitial cystic disease occur in the popliteal arteries; however, fewer cases have been reported in the femoral arteries. A 59-year-old male patient visited the hospital with a complaint of a swelling on the lower extremity that had begun two months earlier. Suspecting deep vein thrombosis based on a physical examination and ultrasonography from another hospital, tests were performed. Magnetic resonance imaging (MRI) was performed for exact diagnosis because venous adventitial cystic disease was suspected by computed tomography venography. The MRI indicated venous adventitial cystic disease as well. Thus, a cystic mass excision was performed. In the end, a cystic mass compressing the common femoral vein that originated from the common femoral artery was diagnosed based on the macroscopic findings. This case is reported because blood circulation in the vein was impeded due to arterial adventitial cystic disease, and the symptoms improved after the cystic mass excision and polytetrafluoroethylene roofing angioplasty.
