OBJECTIVE: The purpose of our study was to evaluate the usefulness of adding n-butyl cyanoacrylate to microcoils to fix the catheter tip in percutaneous implantation of a port-catheter system for hepatic arterial-infusion chemotherapy. SUBJECTS AND METHODS: Ninety-three patients (64 men and 29 women; age range, 38-83 years; mean age, 62.2 years) with unresectable advanced liver cancer underwent percutaneous implantation of a port-catheter system with the catheter tip fixed at the gastroduodenal artery with microcoils and a mixture of n-butyl cyanoacrylate and iodized oil. The rates of successful implantation and complications closely associated with this technique and management of the complications were reviewed. RESULTS: Percutaneous port-catheter placement was successfully performed in all patients. However, in eight patients, complications occurred: hepatic arterial obstruction (n = 5, 5.4%); catheter dislocation (n = 2, 2.2%); recanalization of the gastroduodenal artery (n = 1, 1.1%); or movement of n-butyl cyanoacrylate (n = 1, 1.1%). In five of the eight patients with complications, hepatic arterial-infusion chemotherapy was continued either after observation of the patient to ensure that stability had been established or after treatment using comparatively easy interventional techniques. In three (3.2%) of the 93 patients, planned hepatic arterial-infusion chemotherapy could not be performed because of complications associated with the technique. CONCLUSION: Fixation of the catheter tip in the gastroduodenal artery using a combination of microcoils and a mixture of n-butyl cyanoacrylate and iodized oil is a useful and safe technique in percutaneous port-catheter placement for repeated hepatic arterial infusion chemotherapy.
