title: [Cystic adventitial degeneration. An important differential diagnosis in intermittent claudication].
abstract: The cystic adventitial degeneration is a rare disease, but an important differential diagnosis in patients with intermittent claudication. The amount of fluid in the cysts may vary and cause an intermittent compression of the artery. This explains the frequently intermittent symptomatology, leading to a critical ischemia if there is a complete obstruction of the artery. The histologic findings indicate that adventitial cysts are true ganglions. The intramural, uni- or multilocular cysts contain a gelatinous, muciform fluid. The diagnosis of a cystic adventitial degeneration should be considered in cases of isolated stenosis or occlusion of the popliteal artery. Realtime ultrasound helps to establish the diagnosis. The standard treatment has been surgical and has consisted a resectional and non-resectional technique. The ultrasound-directed percutaneous aspiration as a less invasive technique seems to be an effective treatment for this condition. The course, diagnostic and therapy of four patients is demonstrated.
