“…Extrahepatic collateral arteries frequently supply recurrent tumors in the caudate lobe, mainly owing to the potential anastomosis between the caudate artery and retroperitoneal arteries within the bare area of the liver (24). The most common of these vessels is the right inferior phrenic artery (25,26).…”

Transarterial chemoembolization is the most common treatment for unresectable hepatocellular carcinomas (HCCs). However, when an HCC is located in the caudate lobe, many interventional radiologists are reluctant to perform chemoembolization and percutaneous ablation owing to the tumor's complex vascular supply and deep location. With the advent of C-arm CT, rendering the three-dimensional display of the hepatic artery and detecting the tumor-feeding vessels are possible and can help guide interventional radiologists to the tumor. The common origins of the caudate artery include the right hepatic artery, left hepatic artery, right anterior hepatic artery, and right posterior hepatic artery. The origins of the tumor-feeding arteries of a caudate lobe HCC can vary depending on the tumor's subsegmental location. Caudate lobe HCCs are commonly fed by multiple caudate arteries that are connected. In addition, extrahepatic collateral arteries frequently supply recurrent tumors in the caudate lobe. The caudate artery can supply portal vein thrombi or biliary tumor thrombi in patients with HCC. Several techniques such as preshaping the microcatheter or using the shepherd's hook technique are needed to catheterize the caudate artery in complex cases. Although uncommon, bile duct stricture is a serious complication following selective chemoembolization through the caudate artery. Identification and catheterization of the caudate artery have become possible in most patients by using C-arm CT and a fine microcatheter system, respectively. The authors review the anatomy of the caudate artery with C-arm CT and describe basic technical considerations in selective chemoembolization for caudate lobe HCCs. Unusual circumstances that require catheterization and techniques used for catheterizing the caudate artery are also described.

“…The caudate arteries can initially originate from the extrahepatic arteries, 12 and the right inferior phrenic artery (RIPA) is the most common extrahepatic artery. 12 , 13 , 14 Other less common vessels supplying recurrent tumors include the right gastric artery, the left gastric artery, the pancreatic artery and the adrenal artery. 5 , 7 , 11 The possibility of extrahepatic arterial supply, such as the RIPA, should therefore not be overlooked during hepatic arteriography.…”
