Chinese expert consensus on the modified implantation technique of port-catheter system for percutaneous hepatic arterial infusion chemotherapy(version 2022)

In recent years,hepatic arterial infusion chemotherapy(HAIC),as one of the interventional therapeutic techniques,has been gradually recognized in the treatment of advanced hepatobiliary malignancies. However,HAIC operation technique has no unified standard and varies widely in different clinical centers. Usually,in most clinical centers HAIC is performed in a way of pure puncture plus catheter implantation. In order to meet the requirements of long and continuous arterial infusion and repeated drug administration in HAIC treatment,the use of modified percutaneous hepatic arterial port-catheter system is superior to conventional repeated femoral arterial puncture and catheterization. In the implantation of hepatic arterial port-catheter system,the modified fixed-catheter-tip technique and the intra-hepatic and extra-hepatic arterial blood flow redistribution technique are adopted,these techniques have the advantages of small trauma,low catheter displacement rate,achieving the purpose of whole liver perfusion,higher patient comfort,fewer complications,etc.,which have already been demonstrated in many clinical centers at home and abroad. In order to better standardize the treatment technique of HAIC,the experts who participate in compiling this consensus,through reviewing the literature,combining own clinical practice experience and making full discussion,have reached following agreements concerning the standardized operation process,technical key points,HAIC regimen,prevention and treatment of postoperative complications,maintenance of port-catheter system and related nursing routines.
