“…The arterialized venous flap was able to survive with just precapillary and post capillary venous system while in an ischaemic state. 10 The sudden rise in pressure of the arterialized venous flap right after the anastomosis with the high pressure arterial blood flow causes an active congestion. 11 When the draining by means of the efferent vein is not efficient, deoxygenated haemoglobin accumulates in the flap, causing an ischaemic condition and swelling, discoloration, bullae formation, and finally results in partial necrosis.…”

“…It has been proposed that reverse blood flow and perfusion pressure are probably the most significant factors for flap survival. [10][11][12] Additionally, early neovascularization and plasmatic imbibition may have significant roles. 13 Regardless of the physiologic mechanism, sufficient nutrition is available to keep the flap alive until peripheral neovascularization occurs, restoring conventional antegrade physiology.…”

We report a case of a 58-year-old patient who sustained multiple finger injuries on the right hand. After thorough debridement, two dorsal defects of the middle and ring fingers were covered simultaneously with a single arterialized venous free flap from the right forearm. The flap was used to create a dorsally syndactylized digit which survived completely and was subsequently divided longitudinally. With early flap division, excellent functional and cosmetic result was achieved. We consider the syndactylized venous free flap with early division as a useful option for simultaneous coverage of separate dorsal digital defects.

“…12 This is particularly true for pure venous flaps compared with arterialized venous flaps and larger flaps compared with smaller flaps. Although the exact mechanism of venous flap survival is unknown, a combination of oscillating venous pressure changing direction of blood flow and a reversal of shunting from veins to arteries 1,6,18,22,23 have been postulated.…”
