Vascularized Pedicle Graft of the Lower Trunk for Reconstruction of the Brachial Plexus

Abstract

The middle trunk of an injured brachial plexus was reconstructed using a vascularized graft of the lower trunk, which was expendable because of irreparable damage to the C8 and T1 nerve roots. The graft was transferred on a vascular pedicle of mesoneurium. Useful recovery was achieved at 3 years. This technique helps to overcome the problems of limited supply and secondary sensory deficit of grafts from peripheral nerves, but is possible only if the plexus is explored early, before mobilization and transfer of nerve trunks is precluded by scarring.
