“…The characteristics of the human shoulder and, specifically, the small diameter of the pathway from the chest to the upper limb predispose the neurovascular bundle to external compressions by adjacent structures at different levels of the thoracic outlet during upper limb movements (mostly during abduction). There are a large number of publications (more than 40 review papers in the last 2 years) from diverse specialties (including radiology, vascular medicine, surgery, sports medicine, rehabilitation, and neurology) on physiopathology, etiology, epidemiology, non-invasive diagnosis, invasive imaging, complications, and medical or surgical treatments ( Daley et al, 2022 ; Al-Redouan et al, 2023 ; Hoexum et al, 2023 ; Perdikakis et al, 2023 ; Teijink et al, 2023 ). This large number of publications illustrates the fact that many questions remain unsolved about this troublesome medical issue.…”
