TRANSCATHETER OCCLUSION OF THE GASTRODUODENAL ARTERY

The gastroduodenal arteries of 7 patients were occluded for treatment of duodenal bleeding in 4, hepatic devascularization in 2, and redistribution of blood flow for intra-arterial chemotherapy in one patient. In 6 patients, occlusion was performed with Gianturco coils, and with Gelfoam in one. No major complication was encountered. This approach was successful in the control of bleeding from peptic ulcers, arteriovenous malformation and invasion of duoenum by retroperitoneal metastatic lymph nodes from carcinoma of the testicle. Occlusion of the gastroduodenal artery was utilized for further dearterialization of hepatic neoplasms. Redistribution of hepatic blood flow was accomplished by the occlusion of the gastroduodenal and replaced right hepatic arteries allowing infusion of chemotherapeutic agents into the entire liver through the left hepatic artery.
