Background
A distally based sural flap is a workhorse flap used to reconstruct the distal lower leg and foot. It developed a bad reputation due to venous congestion, leading to flap failure. Herein, we present a new modification in the form of proximal catheterization and distal ligation of the short saphenous vein to relieve flap congestion.
Methods
Twenty patients underwent reconstruction with distally based sural artery flaps for defects around the ankle, distal leg, and foot from June 2019 to March 2021. Distal ligation with proximal catheterization of the short saphenous vein was performed to reduce the risk of venous congestion.
Results
Early flap congestion was observed in five flaps (25%). The venous congestion was relieved by draining congested blood through the catheter. The total amount of blood removed was around 80–100 mL in the first 2 days postoperatively. The flaps healed uneventfully as two flaps with distal 2-cm necrosis healed with dressing.
Conclusions
Distal ligation of the short saphenous vein may prevent venous overloading from the foot and reduce sural flap venous congestion. Proximal catheterization of the vein to relieve flap congestion is an effective flap safety tool.
