ABSTRACT

BACKGROUND:

The relationship between collateral circulation and prognosis after endovascular treatment in anterior circulation strokes has been reported in many studies.

OBJECTIVE:

In this study, we aimed to compare the predictive power of clinical outcome by comparing five different collateral scores that are frequently used.

METHODS:

Among the patients who underwent endovascular treatment in our clinic between November 2019 and December 2021, patients with premorbid mRS < 3, intracranial ICA and/or MCA M1 occlusion, and a pre-procedural multiphase CTA examination were included in the study. Demographic, technical, and duration information about the procedure, major events after the procedure, and clinical outcomes at 3 months were recorded. The mCTA, Tan, Maas, Miteff, and rLMC collateral scores of the patients were evaluated.

RESULTS:

Clinical outcome at 3 months were good in 37 of the 68 patients included in the study (mRS ≤ 2). Only the mCTA and rLMC collateral scores were statistically significantly higher in those with a good clinical outcome. Significant correlation with 3-month mRS was detected only in mCTA and rLMC scores. Although rLMC and mCTA collateral scores showed a statistically significant association with prognosis, they were not sufficient to be an independent predictor of prognosis.

CONCLUSION:

mCTA and rLMC were found to have the highest predictive power of clinical outcome and the highest correlation with the 3-month clinical outcome. Our study suggests that it would be beneficial to develop a new scoring system over multiphase CTA, which combines regional and temporal evaluation, which are the strengths of both collateral scoring.
RESUMO
ANTECEDENTES A relação entre circulação colateral e prognóstico após tratamento endovascular em acidentes vasculares cerebrais de circulação anterior tem sido relatada em muitos estudos.

OBJETIVO:

Neste estudo, nosso objetivo foi comparar o poder preditivo do desfecho clínico comparando cinco escores colaterais diferentes que são frequentemente utilizados.

MéTODOS:

Entre os pacientes submetidos a tratamento endovascular em nossa clínica entre novembro de 2019 e dezembro de 2021, foram incluídos no estudo pacientes com mRS pré-mórbido < 3, oclusão intracraniana de ICA e/ou MCA M1 e exame de CTA multifásico pré-procedimento. Foram registradas informações demográficas, técnicas e de duração sobre o procedimento, eventos importantes após o procedimento e resultados clínicos em três meses. Foram avaliados os escores colaterais mCTA, Tan, Maas, Miteff e rLMC dos pacientes.

RESULTADOS:

Os resultados clínicos aos três meses foram bons em 37 dos 68 pacientes incluídos no estudo (mRS ≤ 2). Apenas os escores colaterais mCTA e rLMC foram estatisticamente significativamente maiores naqueles com boa evolução clínica. Correlação significativa com mRS de três meses foi detectada apenas nos escores mCTA e rLMC. Embora os escores colaterais de rLMC e mCTA tenham mostrado uma associação estatisticamente significativa com o prognóstico, eles não foram suficientes para serem um preditor independente de prognóstico.

CONCLUSãO:

Verificou-se que mCTA e rLMC têm o maior poder preditivo do resultado clínico e a maior correlação com o resultado clínico de três meses. Nosso estudo sugere que seria benéfico desenvolver um novo sistema de pontuação em vez de CTA multifásico, que combinasse avaliação regional e temporal, que são os pontos fortes de ambas as pontuações colaterais.
