title: Angiographic evaluation of carcinoid tumors of the small intestine: the value of epinephrine.
abstract: The angiographic features in 5 cases of carcinoid tumors of the small intestine are discussed. Findings included irregularity and narrowing of the distal mesenteric and intestinal arcade arterial branches, minimal parenchymal stain, and obstructed venous return. A stellate arterial configuration was not noted. In 2 cases in which epinephrine was employed, tumor staining of the primary lesions and their hepatic metastases was markedly enhanced. Possible mechanisms of action for the pharmacoangiographic effect of epinephrine are discussed.
