Journal of Medical Case Reports 2011 5 346 http content 5 1 346 JOURNAL OF MEDICAL CASE REPORTS CASE REPORT Open Access Catheterization and embolization of a replaced left hepatic artery via the right gastric artery through the anastomosis a case report Masaya Miyazaki Kei Shibuya Yoshito Tsushima and Keigo Endo Abstract Introduction Conversion of multiple hepatic arteries into a single vascular supply is a very important technique for repeat hepatic arterial infusion chemotherapy using an implanted port catheter system. Catheterization of a replaced left hepatic artery arising from a left gastric artery using a percutaneous catheter technique is sometimes difficult despite the recent development of advanced interventional techniques. Case presentation We present a case of a 70-year-old Japanese man with multiple hepatocellular carcinomas in whom the replaced left hepatic artery arising from the left gastric artery needed to be embolized. After several failed procedures the replaced left hepatic artery was successfully catheterized and embolized with a microcatheter and microcoils via the right gastric artery through the anastomosis. Conclusion A replaced left hepatic artery arising from a left gastric artery can be catheterized via a right gastric artery by using the appropriate microcatheter and microguidewires and multiple hepatic arteries can be converted into a single supply. Introduction Conversion of multiple hepatic arteries into a single vascular supply is a very important technique for repeat hepatic arterial infusion chemotherapy using an implanted port catheter system 1-4 . In cases in which a replaced left hepatic artery LHA arising from a left gastric artery LGA is present the replaced LHA should be embolized at the proximal portion to convert multiple vascular supplies into a single supply. However catheterization of an LGA using a percutaneous catheter technique is sometimes difficult despite recently .
