Background: This retrospective study aimed to evaluate the safety and efficacy of cutting balloon angioplasty and conventional balloon angioplasty in supra-aortic arterial lesions caused by Takayasu arteritis., Methods: A total of 46 patients with supra-aortic arterial lesions between January 2011 and December 2018 were included. Cutting balloon angioplasty was applied for 17 patients with 24 supra-aortic arterial lesions (group A), while 29 patients with 36 supra-aortic arterial lesions received conventional balloon angioplasty (group B). The preoperative clinical manifestation, operation result, and postoperative outcomes were recorded and compared in the 2 groups., Results: Dizziness, visual disturbance, and unequal/absent pulses were the most common manifestations. The technical success of revascularization was 93.5% (43/46) in patients and 93.3% (56/60) in lesions. The stent implantation rate in group A was significantly lower than that in group B (4.2% vs. 50% in lesions, P < 0.05). Restenosis was the most common complication in both groups. Although the early (≤30 days) and late (>30 days) complications in group A were less than those in group B, there was no significant difference between the 2 groups (P > 0.05). Moreover, the primary-assisted patency of cutting balloon angioplasty and conventional balloon angioplasty at 1, 2, and 5 years were 66.7%, 62.5%, and 62.5% and 61.1%, 58.2%, and 49.8%, there was no significant difference between the 2 groups (P > 0.05), respectively., Conclusions: Compared with conventional balloon angioplasty, cutting balloon angioplasty could be considered a safe and effective alternative for supra-aortic arterial lesions caused by Takayasu arteritis, demonstrating better patency and clinical benefit., (Copyright © 2023 Elsevier Inc.
