Objective: subclavian steal syndrome (sss) is a hemodynamic disorder caused by proximal subclavian artery stenosis, most commonly due to atherosclerosis, resulting in retrograde vertebrobasilar blood flow and impaired cerebral perfusion. This condition may present with neurological symptoms such as dizziness and syncope, as well as ischemic symptoms in the affected upper extremity. In this case report, we aim to highlight the pathophysiology, clinical features, current diagnostic modalities and treatment options of sss in light of the literature, accompanied by a case treated with an endovascular intervention. Case Presentation: We report a case of 63-year-old patient with symptomatic severe subclavian artery stenosis and sss who was successfully treated with endovascular subclavian stent placement. The patient with complaints of headache, intermittent dizziness, and numbness and pain in the left arm. Blood pressure measured on the right arm was 160/88 mmHg, whereas on the left arm it was 100/51 mmHg. a n atherosclerotic plaque causing significant stenosis in the left subclavian artery. a balloon-expandable stent was deployed with balloon angioplasty at 8-10 atm pressure within the stenotic segment. The patient's symptoms resolved completely, and the sss was successfully treated. Conclusions: İn this case report a review of the current literature was also performed to evaluate the pathophysiology, clinical presentation, diagnostic modalities and treatment strategies for sss. subclavian steal syndrome's endovascular therapy, including balloon angioplasty and stent implantation, is associated with lower morbidity compared to surgical intervention and is currently considered the first-line treatment.
