Venous adventitial cystic disease is a very rare disease that can cause deep vein thrombosis: A case report

BACKGROUND

Venous adventitial cystic disease (VACD) is a rare disease characterized by cysts, filled with a gelatinous mucous substance similar to joint fluid, in the adventitia of blood vessels adjacent to the joints. It is often misdiagnosed as deep vein thrombosis (DVT), femoral varices, venous tumors, or lymphadenopathy.

CASE SUMMARY

A 69-year-old woman visited our hospital with a complaint of swelling in the right lower extremity. The patient was diagnosed with DVT and prescribed apixaban at an outpatient clinic. After 3 wk, the patient was hospitalized again because of sudden swelling in the right lower extremity. We diagnosed VACD and performed surgery for cyst removal as well as patch angioplasty and thrombectomy of the right common femoral vein. The patient received anticoagulants for 6 mo and has been doing well without recurrence for 1 year postoperatively.

CONCLUSION

Recurrent VACD requires complete removal of the connections to the joint cavity to prevent recurrence.

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 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.
