Figure 2 (a) Image showing a neuromuscular ultrasound assessment of one of our patients with right thoracic (RT) outlet syndrome. The right arm was assessed at rested position ‘0’ with the normal position of neurovascular bundle (lateral cord ‘LC,’ axillary artery ‘AA,’ axillary vein ‘AV,’ and other cords) under the pectoralis minor muscle (PMN) posterior edge without impingement. (b) The same right arm of the patient with right side thoracic outlet syndrome was assessed at the abducted position more than 120 showing impingement of the same neurovascular bundle (line B-B) under the pectoralis minor muscle posterior edge (line A-A) with the pectoral bowing ratio exceeding 14%.
