title: Hepatic arterial cannulation using the side holed catheter.
abstract: BACKGROUND
  Hepatic arterial infusion chemotherapy (HAIC) has been recognized as one of the effective treatments for patients with hepatic metastatic tumor. However it is difficult to perform HAIC in the long term without complications. This report describes the laparotomic approach using the side holed catheter, which is a novel method of implanting a catheter-port system.
  
  
  RESULTS
  We designed a new anti-thrombotic catheter for HAIC. This catheter is tapered from 5F (diameter of shaft) to 3.3F (diameter at tip), and a side hole is opened 7 cm from the tip of catheter. This catheter is inserted from the gastroduodenal artery to the common hepatic artery (CHA), and the tip is put in the aorta or in the splenic artery. The side hole is adjusted distal to the CHA. In our surgical department, our new catheter was inserted in four patients at the time of their abdominal surgery. The cannulation was performed successfully in all patients. In two of them, HAIC was finished without problems at 6 months after starting, and two were still treated by HAIC at 9 and 8 months after starting.
  
  
  CONCLUSIONS
  Initial results from a study of a new method of implanting a catheter-port system in the hepatic artery using the new tapering side hole catheter suggest that this method may enable operators to avoid complicated selective coiling and may lower the incidence of hepatic artery occlusion in patients receiving long-term HAIC.
