Summary

Free functional muscle transfer (FFMT) using the gracilis muscle as a donor muscle has become a standard treatment for reconstructing late-onset brachial plexus injuries. Successful implementation of this procedure relies on the availability of functional donor vessels in the injured limb to supply the muscle flap. However, some brachial plexus injuries are accompanied by subclavian or axillary artery injuries, which compromise the viability of the muscle flap due to insufficient vascular supply. To address this, arteriovenous (AV) loop grafts have been employed to extend donor vessels to the flap and have been utilized in various body regions, including the upper extremity. Despite their widespread use, AV loop grafts have not been previously utilized in FFMT for late-onset brachial plexus injuries with concurrent subclavian or axillary artery injuries. This study aimed to assess the feasibility of this surgical approach and report the long-term outcomes of the procedure.
