AbstractWe developed a new 2.9 Fr implantable catheter-port system (reservoir) to perform arterial infusion chemotherapy in patients with unresectable liver tumors. This study was undertaken to evaluate the feasibility of placing this new reservoir system in patients in whom placement of a 5 Fr-reservoir system would seem to be difficult because of severe stricture, tortuosity or angulation of the hepatic artery. A new reservoir system was successfully implanted in 25 patients during 27 sessions. After a side hole was opened, a 2.9 Fr catheter was inserted in the distal hepatic artery or in the gastroduodenal artery in 24 sessions. The catheter tip was then fixed with coils to prevent catheter dislocation. In the other 3 sessions, a 2.9 Fr catheter was inserted without catheter fixation in the replaced right hepatic artery and a small sized collateral artery towards the liver. Arterial infusion chemotherapy was done without any trouble after 20 sessions. Catheter dislocation was found after 2 sessions in which the catheter tip was not fixed or inadequately fixed. Early arterial occlusion was found after placing a 2.9 Fr catheter in the replaced hepatic artery and the small sized-collateral artery after 4 sessions. In conclusion, although sequellae should be evaluated over a long-term period, implantation of a new 2.9 Fr reservoir system is technically feasible and useful in performing arterial infusion chemotherapy.
