Application of pocket-first technique for implantation of totally implantable venous access ports

While vascular puncture is always performed before making port pocket in the implantation of totally implantable venous access ports (TIVAP), some surgeons preferred to make port pocket first. This study seeks to verify the safety and feasibility for the pocket-first technique. The study retrospectively reviewed 447 patients who undergone TIVAP implantation from July 2017 to November 2022. All the patients were divided into two groups based on vascular puncture first or making port pocket first. The general information, operation information and post-operative complications were reviewed and analyzed. All the operations were performed successfully. No difference was observed in the sex, age, height, weight, BMI, port location and total complication rate between the two groups. The operation time of the Puncture Group and the Pocket Group were 46.9 ± 22.4 min and 33.8 ± 13.6 min ( P
