Venous bypass drainage of the small saphenous vein in the neurovascular pedicle of the sural flap: Anatomical study and clinical implications

摘要: Background: Little is known about the necessary dimensions of neurovascular pedicle sural flap for inclusion concomitant bypass veins small saphenous vein to secure sufficient retrograde venous flow. Therefore, authors evaluated anatomical basis outflow and were able give recommendations as width be transferred safely. Methods: The collateral pathway was studied in five formalin-preserved cadaver legs. usefulness duplex sonography visualize system legs healthy volunteers. Results: ranged from 1.4 3.1 cm human cadavers 0.09 1.5 group. In both groups, only one side, medial or lateral vein, responsible a total proximal-to-distal bypass. opposite side partly bypassed vein. Ultrasonography alone without Doppler this variable suprafascial network. Conclusion: Preoperative evaluation through essential localize on which are present, making it possible decrease interfering with reliability flap.
