Abstract:

Background and Purpose:

Numerous studies have shown longer pre-hospital and in-hospital workflow times and poorer outcomes in women after acute ischemic stroke (AIS) in general and after endovascular treatment (EVT) in particular. We investigated sex differences in acute stroke care of EVT patients over 5 years in a comprehensive Canadian provincial registry.

Methods:

Clinical data of all AIS patients who underwent EVT between January 2017 and December 2022 in the province of Saskatchewan were captured in the Canadian OPTIMISE registry and supplemented with patient data from administrative data sources. Patient baseline characteristics, transport time metrics, and technical EVT outcomes between female and male EVT patients were compared.

Results:

Three-hundred-three patients underwent EVT between 2017 and 2022: 144 (47.5%) women and 159 (52.5%) men. Women were significantly older (median age 77.5 [interquartile range: 66–85] vs.71 [59–78], p < 0.001), while men had more intracranial internal carotid artery occlusions (48/159 [30.2%] vs. 26/142 [18.3%], p = 0.03). Last-known-well to comprehensive stroke center (CSC)-arrival time (median 232 min [interquartile range 90–432] in women vs. 230 min [90–352] in men), CSC-arrival-to-reperfusion time (median 108 min [88–149] in women vs. 102 min [77–141] in men), reperfusion status (successful reperfusion 106/142 [74.7%] in women vs. 117/158 [74.1%] in men) as well as modified Rankin score at 90 days did not differ significantly. This held true after adjusting for baseline variables in multivariable analyses.

Conclusion:

While women undergoing EVT in the province of Saskatchewan were on average older than men, they were treated just as fast and achieved similar technical and clinical outcomes compared to men.

Résumé:

Résumé:

La thrombectomie mécanique : pas de différence entre les sexes en ce qui concerne les indicateurs de temps et les résultats obtenus en Saskatchewan.

Contexte et but :

Dans de nombreuses études, on fait état de flux de travaux prolongés en phase préhospitalière et hospitalière et de résultats moins favorables chez les femmes que chez les hommes après un accident vasculaire cérébral (AVC) ischémique aigu en général, et notamment après un traitement endovasculaire (TEV). L’étude, fondée sur un registre provincial exhaustif au Canada, avait donc pour but d’examiner les différences de soins donnés aux hommes et aux femmes traités par TEV après un accident vasculaire cérébral aigu, sur une période de 5 ans.

Méthode :

Des données cliniques recueillies sur tous les patients soumis à un TEV après un AVC ischémique aigu, entre janvier 2017 et décembre 2022, en Saskatchewan, ont été inscrites dans le registre OPTIMISE au Canada, puis complétées par d’autres données sur des patients, provenant de sources administratives. Il y a eu ensuite comparaison des données en ce qui concerne les caractéristiques de base, les mesures du temps de transport et les résultats techniques du TEV, entre les hommes et les femmes.

Résultats :

Dans l’ensemble, 303 patients ont subi un TEV entre 2017 et 2022, soit 144 femmes (47,5 %) et 159 hommes (52,5 %). Les femmes étaient significativement plus âgées que les hommes (âge médian : 77,5 ans [intervalle interquartile {II} : 66-85] contre [c.] 71 [59-78]; p < 0,001), tandis que les hommes souffraient davantage d’occlusions intracrâniennes de la carotide interne (48/159 [30,2 %] c. 26/142 [18,3 %]; p = 0,03). Les données relatives au temps écoulé entre le dernier moment où la personne avait été vue en bonne santé et l’arrivée au centre de soins intégrés des AVC (temps médian : 232 min [II : 90-432] chez les femmes c. 230 min [90-352] chez les hommes), au temps écoulé entre l’arrivée au centre de soins intégrés et la reperfusion (temps médian : 108 min [88-149] chez les femmes c. 102 min [77-141] chez les hommes), aux résultats de la reperfusion (reperfusion réussie : 106/142 [74,7 %] chez les femmes c. 117/158 [74,1 %] chez les hommes) et au score de Rankin modifié au bout de 90 jours ne présentaient pas de différence significative, et ce, malgré le rajustement des variables de base dans les analyses plurifactorielles.

Conclusion :

Si les femmes soumises à un TEV en Saskatchewan étaient en moyenne plus âgées que les hommes, le temps écoulé avant le traitement était aussi court que celui enregistré chez les hommes, et les résultats cliniques et techniques obtenus dans les deux groupes étaient comparables.
