Background: The implantation of a subcutaneous implantable venous access device in patients with a gynecological cancer disease could be necessary because of different causes, e.g. application of chemotherapy or parenteral nutrition in case of advanced cancer. 4 years after implementation of the Seldinger-technique in the subclavian vein as standard way of port-catheter-implantation at department of gynecology at the University-Hospital in Ulm a retrospective analysis of complication-rates was performed to define internal standards for this procedure. Methods: Between 01/2014 and 07/2018 we reviewed all patients who received a port implantation at the gynecological department. The standard way of port-implantation used in this cohort was Seldinger-technique. All Data assessed were used anonymously. Patients-characteristics, tumor-entity, surgical and anesthesiological management, morbidity and port catheter associated complications (thrombosis, infections etc.) were analyzed. Results: A total of 638 were included. The implantation was performed in Seldinger-technique. Port catheter implantation was successfully performed in 96.6%. The implantation on the left subclavian vein significantly showed a higher rate of success than in the right subclavian vein (98.2% vs. 95.3%, p=0,036). Significant higher rates of associated thromboses was found in patients with a port implantation on the left side (5.9% vs. 2.0%; p=0.036). Obesity (BMI ≥ 30 kg/ m2) leads to a significant higher rate of venous misplacements (p=0.027). Compared to local anesthesia and analgosedation, general anesthesia leads to a significant lower rate of perioperative complications (20.3% vs. 22.4% vs. 13.1%; p=0.014). Perioperative application of antibiotics seems to reduce postoperative infection rates, even if the results are not significant. Conclusion: Seldinger-Technique is an efficient way for port-implantation. Especially patients with a high potential of complications, like obesity with BMI >30kg/m², or other risk factors, the left subclavian vein should be preferred, as well as general anesthesia. Perioperative application of antibiotics (e.g. single-shot antibiotics) should be considered. Trial registration: retrospectively registered
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
