RÉSUMÉ
Objective To supply morphologic basis for designing the medial antebrachial neurocutaneou vascular flap. Methods Microanatomy and transparent specimens made by colored latex injection were applied to study the surgical anatomy of the medial antebrachial neurocutaneous nerve (MAN) and it's relationship to basilic vein, the origin, orientation,caliber of neurovascular cutaneous perforators and it's nutrient pattern to the MAN. Results The MAN got its blood supply by paraneural vessels which constituted of 4 cutaneous perforators' The paraneural vessels supply not only the MAN,but also it's adjacent flap. The MAN was accompanied by basilic vein about 1 cm away from it. Conclusion Along basilic vein,medial antebrachial neurocutaneous vascular flap could be designed and used to repair soft tissue defects around the elbow and wrist
