title: False aneurysm formation following arteriographic intimal dissection: serial studies in 2 patients.
abstract: Two patients with metastatic islet-cell carcinoma underwent multiple hepatic artery catheterizations for streptozotocin infusion. An intimal flap was raised during one of the initial arteriographic procedures and a false aneurysm developed. The progression of the aneurysm was documented on sequential studies. False aneurysm formation appears to be a relatively unappreciated complication of intimal dissection, and these 2 cases permitted observation of their natural history.
