Percutaneous transluminal angioplasty for vertebral artery origin stenosis under the flow-reversal protection using Mo.MA < sup > ™ < /sup > Ultra: A technical case report

CONCLUSION: In EVT for symptomatic VAOS, lesion cross for distal protection device placement is considered to create a high risk of distal embolism due to the anatomic and clinicopathological characteristics of VAOS lesions, especially in A-to-A embolism cases. The flow-reversal protection using Mo.MA™ Ultra can be performed with EVT to prevent distal embolism with lesion cross by retrograde flow of the VA. This method is feasible, especially for cases in which antegrade flow to the basilar artery through the developed contralateral VA is anticipated during the Mo.MA™ Ultra protection.PMID:38053710 | PMC:PMC10695346 | DOI:10.25259/SNI_746_2023
