Longitudinal Contraction Venoplasty in Prevention of Internal Jugular Vein Thrombosis After Free Flap Vascular Anastomosis

Abstract

Purpose: The vascular anastomosis of free flap with the internal jugular vein stump is susceptible to thrombosis, thus resulting in flap compromise or failure. This study aims to explore the method of longitudinal contraction venoplasty in the prevention of internal jugular vein stump thrombosis after free flap vascular anastomosis and its feasibility.

Patients and methods: A retrospective review was performed of 16 patients who underwent internal jugular vein resection because of cancer ablation and longitudinal contraction venoplasty to prevent internal jugular vein stump thrombosis after free flap vascular anastomosis from January 2013 through December 2014 at Second Xiangya Hospital. The methods for longitudinal contraction venoplasty and its efficacy are reported.

Results: Venous anastomosis of all flaps was performed with the internal jugular vein stump, and single venous anastomosis was made in all cases. Postoperatively, all flaps survived completely, without vascular compromise. All the patients were followed for approximately 9 to 33 months, and they were satisfied with the esthetic and functional results of the donor and recipient sites after reconstruction.

Conclusions: Longitudinal contraction venoplasty may be an effective new method for prevention of internal jugular vein thrombosis after free flap vascular anastomosis.
