Dealing with the venous congestion of free flaps: venous catheterization.

For head and neck reconstruction after tumor ablation surgery, free flaps are mostly the chosen treatment modality for most of the centers. Coping with venous insufficiency and increasing venous outflow of the flap during this process increases the success rate. To increase venous outflow, triple-lumen central venous catheter is inserted to one of the donor veins of the flap that has venous insufficiency and one intact vein anastomosis.
