Case Report

A 45-year-old woman, who was a nonsmoker with a known case of hypertension, presented with a history of pain in her right upper limb on exertion for the past 6 months. There was no history of any neurological symptoms, trauma, or giddiness/syncope. Clinical examination revealed absent brachial, radial, and ulnar pulses with palpable subclavian and axillary pulses. Upper right limb temperature was the same as the left upper limb. There was no evidence of a cervical rib. Neurological examination was unremarkable, and contralateral upper limb and bilateral lower limb pulses were palpable. There was a pressure difference of 30 mmHg in the brachial artery between the 2 upper limbs. Color Doppler revealed occlusion in the proximal and mid-brachial arteries with reformation of the distal brachial, radial, and ulnar arteries. A right transbrachial angioplasty/stenting was planned under optical coherence tomography (OCT) guidance. […]
