Although popliteal venous aneurysms are rare diseases, they can cause pulmonary embolism and deep vein thrombosis. We report a case of popliteal venous aneurysm discovered after pulmonary embolism and treated with venous patch plasty to prevent a recurrence. A patient is 62-year-old man. He became aware of the pain in his left popliteal region. A few days later, he became aware of dyspnea and severe chest pain on exertion, and called for emergency medical assistance, and was transported to our emergency center. CT scan of the chest revealed pulmonary embolism, and thrombolysis started. CT scan of the lower extremities showed a popliteal venous aneurysm in the left popliteal fossa, so he was refered to our department for surgical treatment. The patient underwent surgery using a posterior approach to the left popliteal fossa under general anesthesia. A large amount of obsolete thrombus was found in the venous aneurysm. After we rescected the aneurysm, harvested a small saphenous vein from the peripheral leg, and repaired popliteal vein with venous patch because there was little normal tissue remaining. No recurrence of intravenous thrombus was observed after the surgery and obtained good results.
