Quadrilateral peripheral vascular disease in the young adult.

THIS is a report of seven cases of chronic occlusive arterial disease of the extremities of young adults that initially involved the smaller primary arteries of all four limbs. There were consistent pathologic findings, distinctive arteriograms, and constant clinical features in these cases. The disease process presenting in these patients is easily distinguished from common arteriosclerotic disease. During the period of observation, cases of quadrilateral vascular disease were excluded from this series when they were instances of obvious ordinary arteriosclerosis. Some other cases were excluded because the disease was not quadrilateral although the other findings were typical of the disease to be described.
