Comparison of Internal Jugular Vein System Anastomosis and External Jugular Vein System Anastomosis in Free Flaps for Head and Neck Reconstruction: A Meta-Analysis.

The incidence of thrombosis and flap failure after venous anastomosis in the IJV system was lower than that in the EJV system. The results from the present study have shown that the IJV system should be the first choice for venous anastomosis in the reconstruction of free flaps.
