Chemoembolization for hepatocellular carcinoma via the inferior pancreaticoduodenal artery in patients with celiac artery stenosis.
Twenty-one patients with hepatocellular carcinoma (HCC) accompanied by extensive celiac artery stenosis or obstruction were treated by chemoembolization via the inferior pancreaticoduodenal artery (IPDA). The tip of the catheter was placed in the arteries in front of the confluence with the proper hepatic artery in 12 patients (group A: the proximal portion of the IPDA in 10, and common hepatic artery in 2), and in the proper hepatic artery or branches of it (group B) in 9 using a coaxial catheter system. Transient hyperamylasemia was observed in 10 of the 12 patients in group A and in 3 of the 9 patients in group B after chemoembolization. Splenic infarction developed in 8 patients in group A and in none in group B. Intrapancreatic fluid collection was present in 2 patients in group A following chemoembolization. No fatal complications were encountered. The 1-, 2-, and 3-year survival rates of the 10 patients in group A treated by only chemoembolization were 90, 57, and 23%, respectively (mean survival 780 days). The 1- and 2-year survival rates of 9 patients in group B were 85.8 and 85.8% (mean 879 days), respectively. Considering the severity of complications and the survival rates in groups A and B, chemoembolization by superselective catheterization into the hepatic artery via the IPDA is the treatment of choice. However, chemoembolization from the arteries in front of the confluence with the proper hepatic artery seems to be acceptable in cases of hypervascular HCC which fail to be superselectively catheterized.
