Cystic adventitial disease: A cause of peripheral arterial disease that should be remembered in young adults

Özet

Adventitial cystic disease is a rare peripheral arterial disease characterized by viscous and mucinous cysts in the arterial adventitia. Patientsare usually young individuals without any risk factors for atherosclerosis. A 27-year-old man suffering from pain on his left leg was admitted.He had no history of atherosclerotic risk factors. Attenuated pulses were palpated. Doppler ultrasonography and computed tomographyangiography revealed total occlusion in the femoral artery. Bypass surgery was performed using the vein graft. Histopathological examinationrevealed mucinous degeneration in the vascular wall. In conclusion, when arterial stenosis or occlusion develops in young patients having norisk factors for atherosclerosis, cystic adventitial disease should not be ignored. As frequently encountered in popliteal arteries, it must bedistinguished carefully from popliteal artery entrapment syndrome.
