Cystic adventitial disease of the popliteal artery and of other stem vessels in the extremities.

Two hundred and thirty-four cases of cystic adventitial disease were collected from over two hundred world literatures and were classified into two groups: first, typical cystic adventitial disease of the popliteal artery, and second, that of the stem vessels in extremities other than the popliteal artery. The nomenclatures, clinical and pathological features, and etiology were reviewed. From the etiological point of view, the group in which the cyst was connected with joint capsule was identified as the joint group. All cases reported are listed in the two tables except those cases listed already in Flanigan's table.
