To explore the feasibility and safety of reverse puncture with tunnel needle during the implantation of totally implantable venous access ports to the chest wall.

A total of16 patients who needed long-term intravenous infusion or frequent intravenous infusion were selected,including 11 males and 5 females.The average age was (66.5 ± 6.8) years old (ranging from 50 to 77 years old). The average weight was (65.8 ± 5.2) kg (ranging from 55 to 82 kg). During port placement to the chest wall, the tunnel needle was punctured along the subcutaneous reverse direction through the chest wall port pocket to the internal jugular vein catheter. Then the catheter was connected to the tunnel needle and guided into the chest wall port pocket. After the position of the catheter tip was determined, the length of the catheter was trimmed, and the fixed port was connected. The feasibility and safety of this operation were analyzed to provide a basis for clinical application.

16 cases of port placement to the chest wall were successfully completed. Under the guidance of ultrasound positioning, the success rate of single puncture of internal jugular vein was 100%, and the success rate of reverse puncture of tunnel needle was 100%. There was no vascular and nerve tissue injury.

The tunnel needle reverse puncture guided catheter during ports placement to the chest wall is safe and feasible, with high comfort of patients, low incidence of complications and high success rate, which is worthy of clinical application.
