# Current Advances in Diagnostic and Treatment Approaches for Subclavian Steal Syndrome: A Case Report and Review of the Literature

## TL;DR

A patient with subclavian steal syndrome was successfully diagnosed and treated using modern diagnostic and therapeutic techniques.

## Contribution

This case report demonstrates the successful use of angioplasty and stenting for subclavian steal syndrome.

## Key findings

- Angiography revealed retrograde perfusion of the left vertebral artery and subclavian artery occlusion.
- Angioplasty and stenting reduced symptoms by 50% immediately and eliminated them after one month.
- The patient remained asymptomatic with no neurological deficits during follow-up.

## Abstract

With newly created therapy devices and cutting-edge diagnostic techniques, we successfully diagnosed and treated subclavian steal syndrome in this case report. This case report is complemented by a literature review that examines the current state of knowledge about diagnostic and treatment options. The patient reported pain and numbness in his left upper arm when raising his arm above his head. On clinical examination, he had good left radial and ulnar pulses while in a sitting position; however, he had absent left ulnar pulses when he raised his hand above his head. Angiography revealed retrograde perfusion of the left vertebral artery and nearly complete occlusion of the ostium of the left subclavian artery. The patient underwent angioplasty and stenting. Immediately after the procedure, the patient reported a reduction in the pain and numbness in his left upper limb by 50%, which completely disappeared at his routine follow-up after one month. The patient was completely asymptomatic during follow-up and had no signs of neurological deficit.
