A devised method of hepatic and splenic arterial infusion chemotherapy after transcatheter peripancreatic arterial embolization for patients with advanced pancreatic cancer]

We previously reported the clinical efficacy based on hepatic and splenic arterial infusion chemotherapy (HSAIC) for patients with advanced pancreatic cancer after transcatheter peripancreatic arterial embolization (TPPAE). However, this medical treatment pointed out a few problems in which the method had its complexity and a limited use of embolus micro-coil numbers. Then, we tried to improve the method in solving those problems. In order to reduce the embolus micro-coil numbers for TPPAE, we divided the micro-coil into several parts. We also devised the method of HSAIC. We used one catheter with a side hole, so that the catheter was able to supply a therapeutic drug for arterial infusion chemotherapy, both to the common hepatic artery and splenic artery. The effective rate for eleven cases was 72.7%, and there were no significant differences from the cases treated with the conventional method of TPPAE-HSAIC. Therefore, the devised treatment was considered to be an easy and useful method for TPPAE and HSAIC.
