Abstract

Abstract: Background: The aim of carotid interventions is to prevent cerebrovascular events. Endovascular treatment (carotid-artery-stenting/CAS) has become established as an alternative to open surgery in some cases. Historically, female sex has been considered as a perioperative risk factor, however, there are few studies regarding this hypothesis when it comes to CAS.

Objectives: To analyze the CAS results in our center adjusted by sex.

Methods: A retrospective cohort study was designed, including patients with carotid atheromatosis operated at a single center from January 2016 to June 2019. Our objective was to compare cardiovascular risk, including myocardial infarction, stroke, and mortality, by sex. Follow-up rates of stent patency, restenosis, stroke, myocardial infarction, and death were reported.

Results: 71 interventions were performed in 50 men (70.42%) and 21 women (29.57%). Mean age was 70.50 ± 10.72 years for men and 73.62 ± 11.78 years for women. Cardiovascular risk factors did not differ significantly between sexes. Mean follow-up was 11.28 ± 11.28 months. There were no significant differences in neurological events during follow-up. No adverse cardiological events were detected at any time. Regarding the mortality rate, during medium-term follow up there were 2 neurological related deaths with no significant differences between sexes (p=0.8432). Neither sex had higher rated of restenosis during long term follow-up (5.63% vs. 1.41%, p = 0.9693) or reoperation (1.41% vs. 1.41%, p = 0.4971). All procedures remained patent (<50% restenosis).

Conclusions: Despite the limitations of our study, CAS is a therapeutic option that is as effective and safe in women as in men. No sex differences were observed.

Resumo

Resumo: Contexto: As intervenções carotídeas visam prevenir eventos cerebrovasculares. O tratamento endovascular (implante de stent na artéria carótida) se estabeleceu como uma alternativa à cirurgia aberta em alguns casos. Historicamente, o sexo feminino é considerado um fator de risco perioperatório, mas há poucos estudos abordando essa hipótese em casos de stent de carótida.

Objetivos: Analisar os resultados do CAS em nosso centro ajustados por sexo.

Métodos: Este estudo de coorte retrospectivo incluiu pacientes com ateromatose carotídea operados em um centro de janeiro de 2016 a junho de 2019. Nosso objetivo foi comparar o risco cardiovascular, incluindo infarto do miocárdio, acidente vascular cerebral e mortalidade, de acordo com o sexo. No seguimento, foram descritos patência do stent, reestenose, acidente vascular cerebral, infarto do miocárdio e morte.

Resultados: Setenta e uma intervenções foram realizadas: 50 homens (70,42%) e 21 mulheres (29,57%). A média de idade foi de 70,50 ± 10,72 anos nos homens e 73,62 ± 11,78 anos nas mulheres. Os fatores de risco cardiovascular não diferiram significativamente entre os sexos. A média de seguimento foi de 11,28 ± 11,28 meses. Durante o seguimento, não houve diferenças significativas nos eventos neurológicos. Nenhum evento cardiológico adverso foi detectado. Quanto à taxa de mortalidade, durante o seguimento de médio prazo ocorreram 2 óbitos neurológicos sem diferenças significativas entre os sexos (p = 0,8432). Não foi observada maior taxa de reestenose no seguimento de longo prazo (5,63% vs. 1,41%, p = 0,9693) ou de reoperação (1,41% vs. 1,41%, p = 0,4971) ao comparar os dois sexos. Todos os procedimentos permaneceram pérvios (< 50% de reestenose).

Conclusões: Apesar das limitações deste estudo, o stent de carótida em mulheres é uma opção terapêutica tão eficaz e segura quanto em homens. Nenhuma diferença foi observada entre os sexos.
