However, concomitant BPI and subclavian artery injury are not uncommon. Arteriovenous (AV) loop graft is one of the methods used to extend vessels to areas with vascular depletion. This case series aims to report the feasibility and outcomes of AV loop grafts for FFMT in BPI patients with subclavian artery injury.<\/jats:p><\/jats:sec><jats:sec><jats:title>Patients and Methods<\/jats:title><jats:p>This longitudinal descriptive report included adult patients with BPI and concomitant subclavian artery injury. Patients with adequate intra\u2010operative thoracoacromial and\/or thoracodorsal arterial flow, sufficient for FFMT without the need for an AV loop graft, were excluded.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of the 10 initially enrolled patients, three were excluded: two for adequate intra\u2010operative arterial flow, and one for extensive adhesions around the external jugular vein, precluding the index surgery. Seven patients, with a median age of 37\u2009years, mostly male and injured in motorcycle accidents, were included. Four patients underwent a single\u2010stage operation (AV loop graft and FFMT simultaneously), while three patients underwent a two\u2010stage operation. Success rates were 100% for the single\u2010stage operation and 33% for the two\u2010stage operation. The two\u2010stage operation led to increased operative time, extended hospital stays, and anastomosis mismatch challenges. Successful cases regained gracilis muscle motor power for elbow flexion, achieving grade III\u2010IV within 13\u201329\u2009months.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>FFMT with AV loop graft for BPI patients with subclavian artery injury is feasible and effective.
