Cystic adventitial disease: a case report and literature review

Venous cystic adventitial disease: to cure or manage? A case series

Venous cystic adventitial disease is a rare vascular condition that can have significant effects on a patient's quality of life. The clinical presentation of venous cystic adventitial disease is variable, and there are no established guidelines on investigation or treatment of the disease. We present a series of three patients with venous cystic adventitial disease of the common femoral vein, treated within a single vascular surgery unit. Each of the three patients presented within 18 months of each other, despite the rarity of the disease. These are the only known cases treated within this vascular surgery unit. The investigation, management and treatment of each patient are individualised, with a management focus on quality of life.

Venous Adventitial Cyst Mimicking a Persistent Femoral Deep Venous Thrombosis

OBJECTIVE

We describe the case of lower limb unilateral swelling due to a cystic mass (adventitial cystic disease) compressing on the common femoral vein. This was misdiagnosed as a deep vein thrombosis on both computed tomography venography and Doppler ultrasound.

METHOD

We describe the diagnostic pathways and surgical excision of this venous adventitial cyst of the femoral vein.

CONCLUSION

Venous adventitial cysts are a rare occurrence and diagnosis remains difficult. It often presents clinically as a Deep Vein Thrombosis (DVT). Suspicions should be raised should symptoms persist despite appropriate DVT management. Surgical management include endovascular, minimally invasive procedures, and complete evacuation of the mucoid cyst with excision of the cystic wall.

[Adventitial cyst of the popliteal artery]

Vascular cystic adventitious degeneration (CAD) is a rare disease of unclear etiology that affects mainly the popliteal artery (up to 85-90% of cases). Clinical manifestations are similar to aneurysm of the popliteal artery. CAD occurs mainly in males of the 4^th and 5^th decades of life (range 10-77 years). These patients usually have no risk factors of cardiovascular diseases. Unilateral symptoms prevail. We report a review and a 46-year-old patient with CAD of the popliteal artery.

Cystic adventitial disease of the common femoral vein: A case report

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.

Cystic Arterial Disease Located Only in the Media of the Popliteal Artery: A Case Report

Adventitial cystic disease of the popliteal artery is a rare non-atheromatous peripheral artery disease. In most cases, the cystic lesion is located in the adventitia of the popliteal artery. Herein, we present a rare case of cystic arterial disease in which the cyst was located only in the media of the popliteal artery. We successfully treated the cyst with resection of the affected popliteal artery and reconstruction with an autogenous vein graft.

Cystic adventitial disease of the common femoral vein

We present the case of a 46-year-old commercial pilot with a history of unilateral leg swelling following a flight to Geneva. Although initial clinical examination suggested a deep vein thrombosis, the swelling only partially resolved with anticoagulation and further imaging suggested the presence of adventitial cystic disease (ACD). The patient underwent initial anticoagulation to allow any thrombus to be lysed, followed by excision of the ACD from the venous wall and venous reconstruction. Following the excision of the ACD, providing the patient remains asymptomatic and further imaging finds normal venous anatomy, we hope the patient will discontinue anticoagulation and return to flying.

Cystic adventitial disease of the common femoral artery at a previous surgical dissection site

Cystic adventitial disease (CAD) is a rare vascular disorder associated with nonatherosclerotic peripheral vessel disease and occurs when mucoid cysts in the adventitia compress the blood vessel. The underlying etiology and pathogenesis of CAD remain debatable as various theories have been suggested. This case is interesting because the cyst developed from the previous common femoral artery (CFA) dissection site. To our knowledge, this is the first report of CAD developed at a previous operation site. Thus, we report herein a case of CAD arising from a previous embolectomy dissection site in the CFA that was successfully treated with surgery.

Adventitial cystic disease of the common femoral artery: a case report and literature review

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.

Cystic adventitial disease of the popliteal artery: is there a consensus in management?

Cystic adventitial disease (CAD) is a well described disease entity that commonly affects the popliteal artery, presenting as a rare cause of non-atherosclerotic claudication. The traditional surgical approaches are cyst resection and bypass, or cyst evacuation or aspiration. We report the case of a 58-year-old female with CAD of the popliteal artery treated successfully with cyst resection and bypass using an autologous graft. We reviewed the literature over the last 25 years on management and outcomes of CAD of the popliteal artery. We identified a total of 123 cases; most cases were treated using a traditional repair, while 3 cases used an endovascular approach. The overall success rate using bypass was 93.3%, compared to 85% in the evacuation/aspiration cohort. All cases treated endovascularly resulted in failure. While no consensus exists regarding the preferred modality to treat CAD, we believe that resection of the cyst and bypass affords the best outcomes.

Cystic adventitial disease of the popliteal artery: features on 3T cardiovascular magnetic resonance

Cystic adventitial disease (CAD) of the popliteal artery is a rare vascular disease of unknown etiology in which a mucin-containing cyst develops in the adventitial layer of the artery. We report the case of a 26-year-old male with CAD of the right popliteal artery diagnosed non-invasively with 3 Tesla cardiovascular magnetic resonance and confirmed on post-operative histopathology.

Cystic adventitial disease of the popliteal artery: An argument for the developmental theory

Cystic adventitial disease is a rare non-atheromatous cause of popliteal artery disease. We report a case of a 54-year-old patient with claudication of the right calf caused by cystic adventitial disease. Intra-operatively, a communication between the adventitia and the knee joint was identified. Connections between the adventitial cyst and the nearby joint have been reported in the literature that support the developmental theory. This theory suggests that cystic adventitial disease is a developmental manifestation of mucin-secreting cells derived from the mesenchyme of the adjacent joint. This case is the first, to our knowledge, in which a communication between joint and adventitia has been clearly documented by operative findings.

Adventitial cystic disease of the popliteal artery: a potential cause of intermittent claudication

Adventitial cystic disease (ACD) is an uncommon and rare vascular entity characterized by a highly viscous and mucinous cyst located in the adventitia of an artery. Although first described in the external iliac artery, the disease is more frequently sited in the popliteal artery. ACD characteristically occurs in young adults, mostly male, with intermittent claudication as the initial presenting symptom. As the cyst enlarges, it leads to vascular compression with stenosis or occlusion. Because cystic formation of the popliteal artery is uncommon, the disease is often unrecognized. We report a case of popliteal artery ACD in a 54-year-old woman who was successfully treated surgically.

Cystic adventitial disease of the femoral vein presenting as deep vein thrombosis: A case report and review of the literature

Cystic adventitial disease of veins is a rare condition. We report the case of a 28-year-old man who presented with a swollen leg secondary to obstruction of the common femoral vein as a result of this disease. He underwent excision of the cyst and made a full recovery. The presentation, investigation, treatment and pathology of this condition is discussed.
