case_images: This symptom persisted for two weeks until, on the day of admission, the patient presented with spontaneous laceration of the second finger pulp (Figures 1, 2).
case_images: Palm of the left hand with pallor at the base of the third and fourth phalanx. Cyanosis in the distal phalanges and laceration of the pulp of the second finger can be observed.

case_images: Consequently, a Doppler ultrasound was performed on the affected extremity (Figures 3, 4), which found a monophasic pattern of intermediate resistance throughout the journey of the subclavian artery to the distal third of the brachial artery. 
case_images: Monophasic pattern of intermediate resistance throughout the interrogated path of the left upper limb.

case_images: Three-dimensional reconstruction.. Arrows indicate a circumferential stenosis caused by a mixed atheromatous plaque at the origin of the left subclavian artery, resulting in an approximately 72% reduction in lumen diameter.

case_images: Computed tomography angiography (CTA) of the supra-aortic vessels was performed (Figures 5, 6), which revealed both atheromatous and non-atheromatous plaques at the origin of the left subclavian artery with 65% stenosis.
