Percutaneous superior vena cava puncture for hemodialysis catheter placement

Objective: Central venous occlusion (CVO) refractory to endovascular angioplasty is a critical challenge that threatens hemodialysis vascular access. In the present study, we evaluated the efficacy and safety of tunneled, cuffed central venous catheter (tCVC) placement via percutaneous superior vena cava (SVC) puncture in patients with refractory CVO.Methods: Patients requiring maintenance hemodialysis with refractory CVO who had undergone percutaneous SVC puncture and tCVC insertion at a university-affiliated hospital from January 2016 to June 2020 were included. The pa-tients were followed up until May 2021. The demographic information, complications, and catheter patency were analyzed.Results: A total of 205 patients (105 women [51.2%]; mean age, 61 6 15 years) were included. The SVC puncture and tCVC insertion were successfully performed in 194 patients, for a technical success rate of 94.6%. One patient had experienced a pleura injury and hemothorax and had required urgent thoracotomy. A total of 37 patients had presented with mild chest pain and were prescribed oral nonsteroidal anti-inflammatory drugs. During follow-up of the 194 patients with a successful procedure, catheter dysfunction due to thrombosis had occurred in 66 patients, catheter malposition had occurred in 5 patients, and catheter-related blood stream infection had developed in 6 patients. The 3-year primary patency rate was 64.2%, and the 3-year secondary patency rate was 76.3%.Conclusions: A tCVC placed through a percutaneous SVC puncture had a satisfactory technical success rate and long-term patency rate in patients requiring hemodialysis, providing an optional vascular access for those with exhausted central vein resources. SVC puncture also avoided the use of left-sided catheters and preserved central vein resources. Caution should be given to avoid potential complications such as pleura injury and hemothorax.

Automated summary

This study evaluated the efficacy and safety of tunneled, cuffed central venous catheter (tCVC) placement via percutaneous superior vena cava (SVC) puncture in patients with refractory central venous occlusion (CVO). The procedure had a high success rate and low incidence of complications, with satisfactory long-term patency rates. It provides an optional vascular access for hemodialysis patients and should be further studied and promoted.
