Prophylactic Venous Supercharging in Deep Inferior Epigastric Artery Perforator Flap Surgery: A Retrospective Dual-Center Study.

 Our study suggests that venous supercharging of DIEP flap by performing dual venous anastomosis can be routinely and safely done prophylactically, and thus not only after intraoperative assessment of venous congestion, to avoid flap venous congestion and decrease the rates of re-exploration.
