Influence of body mass index on functional and surgical outcomes in transaxillary thoracic outlet decompression for neurogenic thoracic outlet syndrome.

Objective: Despite an increase in prevalence of obesity over the last decades, few studies examine the influence of body mass index (BMI) on the outcome of thoracic outlet decompression (TOD) for neurogenic thoracic outlet syndrome (NTOS). However, it is important to understand the safety and efficacy of this procedure in patients with elevated BMI. This study aimed to determine the influence of BMI on surgical and functional outcomes following transaxillary TOD in patients with NTOS.
