Abstract：Objective To explore the effects and technical notes of Gateway balloon and Wingspan stent for the treatment of severe symptomatic intracranial artery stenosis (SIAS). Methods Clinical data of 62 patients with severe SIAS were analyzed retrospectively, and the rate of artery stenosis was 75.15%± 10.70%, National Institute of Health stroke scale (NIHSS) score was 2.50 ± 3.31 and the modified Rankin scale (mRS) score was 1.27 ± 0.91 before the operation. Simple Gateway balloon dilatation was performed in 5 patients, while balloon-assisted Wingspan stenting was performed in 57. All the patients were followed up for a mean time of 8.7 months, ranged from 3 to 14 months. Results Balloons and stents were in the correct place in all the patients. The rate of artery stenosis, NIHSS and mRS scores were 17.69%± 10.12%, 1.23 ± 1.92 and 0.97 ± 1.10 respectively after the operation, and compared with the preoperation, the differences were found to be statistically significant (P<0.05). Postoperative cerebral infarction occurred in 4 patients, including perforator infarction in 2 and antiplatelet treatment related infarction in 2, and the mRS were achieved 2 to 3 scores after treatment in these patients. The artery stenosis was improved well in 5 patients with simple Gateway balloon dilatation, and no complication such as cerebral infarction occurred. Conclusions Endovascular interventional treatment is safe and effective for serve SIAS, while simple balloon dilatation may be more beneficial to some patients.
