A new indwelling catheter, G-spiral (GSP), was developed for hepatic arterial infusion chemotherapy (HAIC) by way of an implanted catheter-port system (CPS). Here we evaluated its physical properties and the outcomes of its clinical use. The GSP vessel-fixing power and its ability to follow a guidewire were determined with a vascular in vitro model, and Student t test was used to determine statistical significance (P < 0.05). A retrospective analysis was performed to evaluate the technical success rate and to identify the clinical complications associated with radiologic CPS implantation with GSP in 65 patients with unresectable hepatic tumors. The mean vessel-fixing power of the GSP (14.4 g) significantly differed from that of a GSP with a cut shape-memory alloy (3.3 g). The mean resistance to following the guidewire displayed by the GSP (88.5 g) was significantly less than that for a 5F W-spiral (106.3 g) or 4F Cobra-type angiographic catheter (117.8 g). The CPS was placed successfully in 64 of 65 cases (98.5 % ). Hepatic artery occlusion was observed in one case. Occlusion, cracking, and infection of CPS were observed in one, two, and one case, respectively. The GSP is a highly useful indwelling catheter that can be used for HAIC.
