前腕留置型中心静脈ポートシステム抜去に関する検討

抄録

Central venous ports are commonly used for systemic chemotherapy and nutritional management in home care. Removal of the central venous port from adult patients has been reported. We examined 297 patients who underwent removal of an indwelling forearm central venous port system in the preceding 2 years to determine the factors that prevented removal. The mean age was 68.3±12.0 years; the mean duration of indwelling was 1,066.1±1,071.2 days; the minimum duration was 5 days; and the maximum duration was 5,840 days (approximately 16 years). The most common implantation sites were the left forearm and basilic vein. In 19 (6.4%) cases, removal was unsuccessful. The cutoff for non-removable cases was 1,768 days (4.8 years). We recommend the removal of a central venous port implanted in the forearm for chemotherapy within 4.5 years.
