Adventitial cystic disease of the femoral vein in a 5-year-old boy mimicking deep venous thrombosis

Cystic Arterial Disease Localized in the Media of the Popliteal Artery With Dissection

Adventitial cystic disease (ACD) of the popliteal artery is a rare disease that can cause intermittent claudication, and most cases show cysts located in the adventitia. We report a rare case with a cyst localized in the media and a dissection. The patient presented to the hospital with sudden-onset right lower limb pain. A lower limb ultrasound revealed an iso-echoic lesion in the right popliteal artery, leading to an initial diagnosis of thrombotic occlusion and subsequent thrombectomy. However, intravascular ultrasound suggested the lesion was outside the intima, and magnetic resonance imaging findings indicated ACD. Consequently, cyst resection with expanded polytetrafluoroethylene (ePTFE) graft reconstruction was performed. Histopathological examination revealed dissection associated with cystic medial necrosis. However, the condition was diagnosed as cystic arterial disease due to its similarity to previously reported cases and the inadequacy of the term "adventitial" cystic disease.

Adventitial Cystic Disease of the Popliteal Vein, a Rare Cause of Lower Limb Deep Vein Thrombosis

Introduction

Cystic adventitial disease (CAD) is characterised by the accumulation of gelatinous fluid within the adventitial layer of a blood vessel. Over 90% of CAD occurs in the arterial system. Venous CAD most commonly involves the iliofemoral rather than the popliteal segments.

Report

This is the report of a 49 year old female patient with a previous right leg deep vein thrombosis (DVT). She presented to a vascular outpatient appointment with recurrent right lower extremity swelling. Venous duplex ultrasound showed an ectatic and incompetent right popliteal vein. Computed tomography (CT) venography showed focal ectasia of the right popliteal vein resulting from an eccentric low density cyst with a diameter of 15 mm. Under general anaesthesia, the patient was placed in the prone position. A lazy S incision was performed in the right popliteal fossa. The popliteal vein had an eccentrically thickened lateral bulge. After heparinisation, a longitudinal venotomy, endophlebectomy, and en bloc cyst removal were performed sequentially. Popliteal patch venoplasty was performed subsequently using the ipsilateral small saphenous vein. After six months, the patient remains on rivaroxaban. A follow up venous duplex ultrasound showed vein reflux through a standard calibre popliteal vein without evidence of cyst recurrence.

Conclusion

Venous CAD is a rare disease and should be considered if previous DVT or symptoms mimicking DVT occur. Cyst resection and reconstruction with vein patch, venous or synthetic graft is the most commonly used strategy and has lower rates of cyst recurrence and need for re-operation.

•

Venous cystic adventitial disease is rare.

•

Adventitial vein cysts may cause oedema and vein thrombosis.

•

Venous ultrasound is the first diagnostic test.

•

Complete cyst wall excision is crucial to prevent recurrence.

Adventitial cystic disease of the common femoral vein: an unusual cause of lower extremity swelling and review of the literature

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.

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.

Inconsistent Use of Terminology and Different Treatment Outcomes of Venous Adventitial Cystic Disease: A Proposal for Reporting Standards

Adventitial cystic disease (ACD) is a very rare condition characterized by the accumulation of a cyst filled with gelatinous substance in the adventitia of a vessel adjacent to the joint area. The cyst usually compresses the vessel lumen, causing claudication or leg swelling. The disease usually affects the popliteal artery. However, several cases of venous ACDs particularly in the common femoral or external iliac vein have been reported. The definition, diagnosis, and optimal treatment of ACD remain controversial because of its rarity and the inconsistent use of terminology. The heterogeneity of the reported cases is more prominent in venous ACD. Herein, the accurate terminology of cysts correlated to the joint (synovial cyst, ganglion cyst, and adventitial cyst) and the pathogenesis, anatomy, and optimal therapy of venous ACD are discussed in detail to establish reporting standards for future studies.

Long-term follow-up of adventitial cyst surgical excision in external iliac vein

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.

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.

Treatment Options for Venous Cystic Adventitial Disease: A Case Report and Literature Review

Venous cystic adventitial disease (CAD) is an uncommon vascular anomaly that most frequently affects the common femoral vein. Transluminal or transadventitial evacuation followed by cyst excision is considered an effective treatment for this condition, although the recurrence rate is relatively high. Herein, we report a case of a 59-year-old man with venous CAD that was successfully treated with saphenous vein patch angioplasty after mucoid evacuation and cyst excision, and we discuss the options for treating venous CAD.

Cystic Adventitial Disease of the Common Femoral Vein Successfully Treated with Resection, Synthetic Graft Reconstruction, and Fistula Creation

Cystic adventitial disease (CAD) is a rare, benign disease of blood vessels which most commonly affects the popliteal artery. Less than 50 cases of CAD affecting veins have ever been described in the literature to date. We report the case of a 56-year-old woman who presented with unilateral lower extremity swelling and varicosities due to CAD of her common femoral vein. Resection and reconstruction with a venous interposition graft, employing a polytetrafluoroethylene graft and arteriovenous fistula in order to maintain venous bypass patency, were performed successfully. The patient recovered well without any evidence of recurrence or postoperative complications.

Cystic adventitial disease-case series and review of literature

Cystic adventitial disease (CAD) is a rare vascular disorder that involves the arteries and rarely the veins, most commonly found in the popliteal artery of male patients. Etiology of CAD is uncertain and currently without a consensus agreement. Clinically, the most common presenting symptom is claudication. Diagnosis requires a strong clinical suspicion in patients with intermittent claudication, but without other risk factors for atherosclerotic disease. Angiography, ultrasound (US), computed tomography (CT) and magnetic resonance imaging (MRI) can all be used for diagnosis. Treatment of CAD can be done via surgical resection or percutaneous intervention such as aspiration. CAD can rarely recur after treatment.

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.

Venous Adventitial Cystic Disease: A Review of 45 Cases Treated Since 1963

Purpose. To review and identify the most accurate ways of diagnosing and treating adventitial cystic disease (ACD) of the venous system. Methods. Cases of ACD were collected through three popular medical databases, including PubMed, Cochrane, OVID, and MEDLINE. After reviewing the literature, the sites of occurrence of 323 cases of adventitial cystic disease were documented, and all cases of arterial ACD were excluded. The clinical features, treatment, and subsequent course of 45 cases of venous ACD are included in this paper. Results. After reviewing all 45 cases of venous ACD , we have confirmed that the most common vessel affected is the common femoral vein, which reproduces the most common symptom of venous ACD: asymmetric lower extremity swelling worsening over time. Conclusion. Venous ACD most commonly affects the common femoral vein. When unilateral leg swelling occurs with or without a noticeable mass, ACD should be considered. It is best confirmed with CT venography and the treatment of choice is transluminal cyst evacuation and excision.

Doença cística da adventícia na veia basílica: relato de caso

A doença cística da adventícia é uma entidade rara que acomete principalmente a artéria poplítea. A ocorrência em veias é muito rara, e sua etiologia é desconhecida. Clinicamente, apresenta-se como isquemia, trombose ou dor a depender do território acometido. Apresentamos o caso de um paciente masculino jovem referindo nódulo no braço esquerdo. A angiorressonância magnética do membro mostrou lesão cística em contato com a veia basílica, com conteúdo homogêneo e sem realce pós-contraste. Foi realizada ressecção da lesão em bloco com o segmento venoso envolvido. O estudo anatomopatológico foi sugestivo de cisto de adventícia de veia basílica.

A contemporary review of venous adventitial cystic disease and three case reports

Venous adventitial cystic disease is a rare vascular disease. The objective of the study is to contemporarily review the literature of venous adventitial cystic disease and report three other new cases of adventitial cystic disease in common femoral vein. Articles published between 1947 and April 2013 were searched in OVID and PubMed databases. The search yielded only 38 reported cases of venous adventitial cystic disease. The general characteristics and disease management information of the 41 cases (including our current 3 cases) were analyzed. Venous adventitial cystic disease could develop late in life with an average age of 48.39 years (range, 5 to 77 years). Similar to arterial adventitial cystic disease, venous adventitial cystic disease was also found to have a male predominance (male to female ratio, 1.28:1). The common femoral vein was the most likely vein to be involved (65.9%, 27 cases). Right and left sides were almost equally affected. Extremity swelling (86.8%, 33 cases) was the main symptom of patients presenting with venous adventitial cystic disease. Excision of cyst wall in 30 patients (73.2%) was the main surgical procedure with a recurrence rate of 11.5%. Thirteen involved veins were resected; of which, 10 were reconstructed with prosthetic or autologous graft. No recurrence was reported in these 13 patients. Postoperatively, nine cases received an anticoagulation therapy. In conclusion, the etiology, treatment strategy, and outcomes of venous adventitial cystic disease could not be well understood in the present review due to limited numbers of cases. Studies with careful follow-up for at least up to first several months are recommended.

Cystic Adventitial Disease of the Common Femoral Vein

We report on a 52-year-old female patient who presented with a 6-month history of right lower extremity swelling and tenderness. The patient was treated as an outpatient with full anticoagulation, without any improvement. Her medical history was significant for hypertension and high cholesterol, and she had a full coagulopathy profile that was negative for any hypercoagulable syndrome. On examination, the patient was moderately obese, with significant tenderness over the medial aspect of the right groin. A venous duplex examination revealed hypoechoic structure ± acute deep vein thrombosis of right common femoral vein (CFV). A computed tomography of the venous phase revealed an eccentric compression over the medial wall of the right CFV. During surgical exploration, adventitial cystic mucinous disease was enucleated from the medial wall of the right CFV, and the pathological examination confirmed the diagnosis. The postoperative course was uneventful, and all swelling and tenderness were completely resolved. The patient continued to do well, and she had an unremarkable venous duplex evaluation at her 6-month follow-up.
