While dissecting the medial antebrachial cutaneous nerve and the basilic vein, a long, thin tendon that crossed deep into the vein was detected in the lower third of the arm.
In the lower third, this tendon was transiting medially, taking relation with the deep aspect of the basilic vein and the medial antebrachial cutaneous nerve, applied to the medial head of the brachial triceps muscle.
Axial splitting of the
medial antebrachial cutaneous nerve facilitates second-stage elevation of basilic or brachial vein in patients with arteriovenous fistula.
After debridement, the
medial antebrachial cutaneous nerve was harvested as a nerve graft and used for repair.
The components of Type I (45% or 90 of our specimens) included a branch to the posterior antebrachial cutaneous nerve, a branch to the anterior and lateral parts of the axilla, a branch to the medial side of the arm, and a branch to the
medial antebrachial cutaneous nerve. Type II (25%) describes the ICBN arising from T2 and giving off a branch to the brachial plexus.
The
medial antebrachial cutaneous nerve is a sensory nerve that branches out directly from the medial cord of the brachial plexus and innervates the skin on medial side of the forearm.
The
medial antebrachial cutaneous nerve gives branches to innervate the medial elbow and forearm.

Medial antebrachial cutaneous nerve: anatomical relationship with the medial epicondyle, basilic vein and brachial artery.
The other conduction studies of ulnar, median, and
medial antebrachial cutaneous nerves of both upper extremities, radial nerve of left upper extremity, peroneal, tibial and sural nerves of left lower extremity, F waves of right and left median and ulnar nerves were considered normal.
