Abstract.

The aim of this study was to evaluate the incidence of catheter tip dislocation in patients with percutaneously implanted port-catheters for hepatic arterial chemotherapy with catheter tip fixation. Forty-seven patients (31 men and 16 women; mean age 66 years) with unresectable advanced liver cancers (primary liver cancer, n=19; metastatic liver cancer, n=28) underwent percutaneously implantable port-catheter system placement with the tip fixed at the gastroduodenal artery with coils and side hole opened at the common hepatic artery. In 39 patients, n-butyl cyanoacrylate (NBCA) mixed with Lipiodol was added for fixation. The position of the side hole after the indwelling port-catheter system was investigated, and the correction method in cases with catheter dislocation was determined. In 2 (25%) of the 8 patients without NBCA fixation, dislocation of the catheter was noted, in contrast to none (0%) of 37 patients with NBCA fixation. Two patients in whom NBCA was used could not undergo long-term intra-arterial chemotherapy because of hepatic arterial thrombotic occlusion which occurred after placement of the indwelling catheter, and were excluded from the evaluation. Fixation of the catheter tip with combined use of coils and NBCA–Lipiodol mixture to the gastroduodenal artery is important to prevent dislocation of the port-catheter system.
