Prevention of pinch-off syndrome in postoperative complications of totally implantable central venous access ports

Abstract

Objective To evaluate the occurrence and prevention of pinch-off syndrome in post-operative complications of totally implantable central venous port. Methods From October 2003 to September 2016, 628 cases underwent implantable central venous port via the subclavian vein using the landmark venipuncture technique. From February 2014 to September 2016, 106 cases underwent implantable central venous port gaining subclavian venous access. Retrospective analysis of two groups of pinch-off syndrome after totally implantable central venous port. Results pinch-off syndrome were not found in the ultrasound-guided group, pinch-off syndrome occurred in 9 patients of 628 cases underwent implantable central venous port via the subclavian vein using the landmark venipuncture technique during follow-up period. Conclusions Subclavian venous access cannulation on the lateral side of mid-clavicular line by ultrasound guidance was found to be associated with absence of pinch-off syndrome. This method appears to reduce or prevent pinch-off syndrome occurrence after implantable central venous port, therefore improving the safety of the long-term management of implantable central venous port.
