Complications of an implantable venous access device (Port-a-Cath) during intermittent continuous infusion of chemotherapy

Abstract

In 149 patients, treated with intermittent continuous infusion of different chemotherapeutic agents, 169 Port-a-Caths were implanted by qualified surgeons and residents in training. The peri- and postoperative complications of implantation of the Port-a-Cath system and the complications during treatment were retrospectively analysed. The Port-a-Cath was in situ for a total of 36247 days (median 181, range 1-1332). Of the 169 catheters, major complications occurred during treatment, with infection in 4 patients (2.4%), occlusion in 3 (1.8%), thrombosis in 8 (4.7%), extravasation in 8 (4.7%) and migration in 3 (1.8%). The peri- and postoperative complication rate was low, although pneumothorax occurred in 6 patients (3.6%). In 25 patients (14.8%) the Port-a-Cath had to be explanted due to complications. It can be concluded that continuous infusion of chemotherapy via a Port-a-Cath system is a relatively safe procedure, although major complications do occur. The experience of the surgeon could not be related to the complications.
