Comparison of Intraoperative Ultrasound-guided Versus Technique Modified Subclavian Vein Puncture During Implantation of Totally Implanted Port

Objective To compare the success rate and complication rate between real-time ultrasound-guided and technique modified methods of right subclavian vein puncture in tumor patients during implantation of totally implanted port, and to evaluate their effectiveness and safety.

Methods We randomly divided 260 tumor patients into ultrasound-guided group and technique modified group, and compared the success rate, pneumothorax, arterial injury, ectopic catheter, local hematoma, puncture times, pinch-off syndrome, etc.

Results The success rate of primary puncture in the ultrasound-guided group was better than that in the technique modified group (96.92% vs. 86.15%, P=0.002). The overall complication of the ultrasound-guided group was lower than that of the technique modified group (0 vs. 9.23%, P < 0.001). The incidence of pneumothorax (0 vs. 3.85%, P=0.024) and accidental arterial injury (0 vs. 3.08%, P=0.044) in the ultrasound-guided group were lower than those in the technique modified group. There was no arteriovenous fistula and pinch-off syndrome in any group.

Conclusion Compared with the technique modified group, the ultrasound-guided group has more advantages in puncture. Patients with vascular variability can be detected in time.
