Objective: This study aimed to present our experience in patients with subclavian steal syndrome diagnosed by Doppler ultrasonography (US) and treated by endovascular primary stenting. Material and Methods: Fifteen patients with a mean age of 63.5 years (range 45-85) referred to our hospital with dizziness, weakness and numbness in arms between March 2013 and May 2015 were included in the study. Upper extremity-carotid-vertebral artery Doppler US and digital substraction angiography (DSA) revealed subclavian-steal syndrome. Endovascular technique was preferred as the treatment modality. Patients were followed up with clinical and Doppler US findings. Results: Doppler US findings were compatible with complete subclavian-steal syndrome in 10, patients and partial subclavian-steal syndrome in five patients. Left subclavian artery was affected in 12, and right subclavian artery was affected in three patients. Those patients were referred to DSA for further evaluation and treatment. DSA revealed total occlusion in subclavian artery in 10 patients, and 70-80% stenosis in five patients. The mean length of the occluded segment was measured as 14.6 mm (6-30 mm) in 10 patients with total occlusion. In three patients, endovascular treatment could not be performed either with femoral or brachial artery approach. Occlusions and stenosis were treated by using balloon expandable stents in 12 patients. In addition, percutaneous transluminal angioplasty was applied to ensure complete patency in two patients. The mean follow-up time was 15 months (3–28 months) for 12 patients. Conclusion: Although there are different surgical methods in the treatment of symptomatic subclavian-steal syndrome, endovascular technique is a preferable method due to its high technical success and low rate of complications in short and medium term.
