Stenting for atheros clerotic subclavian artery stenosis/occlusion A retrospective case series analysis and follow-up results / 国际脑血管病杂志

ABSTRACT

Objective To investigate the efficacy of endovascular stenting complicating other craniocervical artery stenosis (OCAS) in patients with atherosclerotic subclavian artery stenosis/occlusion (SASO).Methods The clinical data of receiving endovascular stenting therapy in patients with atherosclerotic SASO were analyzed retrospectively,including demographic characteristics,vascular risk factors,complicating OCAS,as well as stenting for SASO and follow-up results.Results A total of 65 patients with SASO were included in the study,47 of them were males and 18 were females (mean age of 64 ± 9 years).Forty-six patients (70.8％ ) complicated OCAS.The overall technical success rate was 95.4％,in which the patients with stenosis (n =58) were 98.1％ and those with complete occlusion (n =7) were 71.4％.The complications occurred in 4 patients.There were no intervention-related serious stroke and death.Mean follow-up was 24 ± 19 months,6 patients with restenosis and 10 with clinically relevant events were found.They mainly occurred in patients with OCAS.The first angioplasty patency rates were 94.5％,81.8％ and 81.8％,respectively at 12 and 24 months after procedure and at the end of follow-up.The survival rates of no clinically relevant events were 92.9％,74.6％ and 68.3％,respectively.Conclusions Endovascular stenting can safely and effectively treat the SASO patients complicating OCAS.Its overall clinical outcome may be affected to some extent by OCAS.
