Clinical application of ultrasound-guided totally implantable venous access ports implantation via the posterior approach of the internal jugular vein.

Background: To determine the feasibility and safety of ultrasound-guided totally implantable venous access port (TIVAP) implantation via the posterior approach of the internal jugular vein (IJV).

Methods: From September 2021 to August 2022, 88 oncology patients underwent ultrasound-guided implantation of TIVAPs via the posterior approach of the IJV for the administration of chemotherapy. The catheter tip was adjusted to be positioned at the cavoatrial junction under fluoroscopic guidance. Clinical data including surgical success, success rate for the first attempt, intraoperative, and postoperative complications were all collected and analyzed.

Results: All patients underwent successful surgery (100%), whereby 58 were via the right IJV and 30 via the left IJV, and the success rate for the first attempt was 96.59% (85/88). The operation time was 20 to 43 minutes, with an average of 26.59 ± 6.18 minutes with no intraoperative complications. The follow-up duration ranged from 1 to 12 months (mean = 5.28 ± 3.07) and the follow-up rate was 100%. The rate of postoperative complications was 4.55% (4/88), including port-site infection in two cases, fibrin sheath formation in one case, and port flip in one case. No other complications were observed during follow-up.

Conclusion: Ultrasound-guided TIVAP implantation via the posterior approach of the IJV is feasible, safe, and effective, with a low rate of intraoperative and postoperative complications. Not only was the curvature of the catheter device smooth, but patients were satisfied with the comfort and cosmetic appearance. Additionally, we could reduce the possible complications of pinching and kinking of the catheter by using this approach. Therefore, further large-sample, prospective, and randomized controlled trials are warranted.
