Abstract
The use of the subcutaneous Port-a-Catheters (Port-a-Caths) provides an important mean of venous access for oncological patients. The aim of our retrospective consecutive single-centre study was to investigate Port-a-Cath-related complications in 252 cancer patients. Overall period of Port-a-Caths maintenance was 25 months. The strategy of our centre is to keep Port-a-Caths in situ up to the end of follow-up in adjuvant cancer patients. A total of 22 complications were recorded (8.73%). Interventional complications occurred in four patients. The main complications during Port-a-Cath use included thrombosis (4 patients, 1.58%), infections (4 patients, 1.58%), persistent pain or discomfort (3 patients, 1.19%) and dislocations (2 patients, 0.79%). Median time to the occurrence of any type of complications was 4.5 months. Eleven Port-a-Caths were removed due to complications (4.36%). Similar rate of Port-a-Cath-related thrombosis/infection was seen in adjuvant and advanced cancer patients (no statistical significance). Continuous infusion of anticancer therapy via a Port-a-Cath system is a relatively safe procedure, although major complications might occur. We are first to describe heparin-induced delayed hypersensitivity after heparinisation of Port-a-Cath. This fact should influence the preference to keep the Port-a-Cath after completion of adjuvant anticancer treatment.
