Objective:
Microvascular free-tissue transfer (M-FTT) is a surgical technique for traumatic injuries that allows tissue reconstruction based on donor tissue composition. The aim of this study is to describe the surgical experiences of M-FTT for reconstruction of complex soft tissue injuries in the lower extremities of a Hispanic population.
Methods:
This is a descriptive study of all M-FTT procedures performed by a single plastic surgeon from 2012 to 2016 at Puerto Rico Medical Center. Demographics, admission diagnosis, mechanism of trauma, type of free flap, co-morbidities, length of stay, donor site and complications were evaluated.
Results:
Eight patients who underwent single M-FTT procedures at lower extremity were enrolled in the study. The average age at time of surgical reconstruction was 36.9+13.2 years with six males and two females. The transfer procedures were performed using donor sites of six rectus abdominis flaps and 2 radial forearm flaps. Posterior tibial artery was used in 62.5% and popliteal artery were used in 37.5% as recipient arteries. Average surgical time was 4.4+0.7 hours with an average length of hospital stay of 22.9+20.1 days. Post-operative complications were reported in three M-FTT procedures: two cases who suffered venous thrombosis and one case who suffered partial necrosis.
Conclusion:
The M-FTT offers an adequate surgical option for patients who present with complex soft tissue traumatic injuries at the lower extremities.
