Long-term outcome of partial resection in venous adventitial cystic disease

Venous adventitial cystic disease is extremely rare. Therefore, standard treatment methods have not been clearly defined. Some reports suggest that complete cyst removal is an effective treatment. However, considering the relatively high recurrence rate, follow-up periods were short. Herein, we report the case of a 75-year-old man with venous adventitial cystic disease successfully treated with partial cyst wall excision. No recurrence was observed for 10 years postoperatively. This case suggests that complete cyst wall excision might not be necessary for the treatment of venous adventitial cystic disease.
