Abstract
Adventitial cystic desease is a rare condition which is a cause of intermittent claudication. We report the case of a 68-year-old man with adventitial cystic disease of the right popliteal artery which was diagnosed using IVUS. The patient complained of intermittent claudication and chest pain. Stenoses of the coronary artery and the right popliteal arteryere were found. PCI was performed to for this coronary artery disease. On IVUS the cause of the popliteal artery stenosis was found to be multiple cystic lesions. Therefore, the tumor was successfully treated by surgical excision followed by artificial graft replacement. The cystic tumor contained mucoid material and was partially lined by multiple rows of cells. The lumen of the removed vessel was normal. Sometimes, adventitial cystic disease of the popliteal artery can resolve spontaneously with the application of pressure, and the patient's various symptoms may disappear. In such cases, careful examination is necessary.
