The Angiographic Discovery and Interventional Disposition of Extrahepatic Supplying Artery in Hepatic Carcinoma

Hepatic Tumor-supplying Artery may rises from non-celiac trunk——superior mesenteric artery; right inferior phrenic artery etc——extrahepatic supplying artery （ESA）. The vacancy or incompletion of intrahepatic artery branches and incomplete homogeneous tumor-stain in celiac trunk angiography, and the tumor near the top of liver suggst the existence of ESA possiblly. Through the ESA, the routine aniicancer drug infusion can be carried on. The route and branches of ESA and hepatic artery should be considered when embolizing via ESA. Generally, it is possible and safe to embolize tumor via the right phrenic artery if it supplies the tumot.
