Abstract

Background

Ischemic stroke due to Large Vessel Occlusion (LVO) represents a critical and time-sensitive neurological emergency. Advancements in imaging technology and endovascular therapies have transformed the management of LVO. Nonetheless, thrombectomy failure diminishes the chances of patients achieving a favorable clinical outcome.

Objective

We aimed to determine the factors influencing recanalization failure in order to optimize thrombectomy therapy along with enhancing patient outcomes.

Methods

A retrospective analysis was performed employing consecutive LVO patients who underwent Endovascular Thrombectomy (EVT) in a tertiary comprehensive stroke center between January 2020 and June 2024. Recanalization failure (mTICI 0-2a) following thrombectomy was assessed using the Kolmogorov-Smirnov test, χ2 test, Fisher’s exact test, and multivariable logistic regression to identify the related factors.

Results

A total of 82 EVT patients were analyzed. The mean age was 58.20 years and 70.73% of the patients were male. The rate of recanalization failure was 61%. Multivariable logistic regression analysis with age-sex adjusted factors has revealed hypertension [aOR: 5.31 (95% CI: 1.23-22.77); =0.025] and no IVT [aOR: 2.75 (95% CI: 1.06-7.14); =0.037] to be independent predictors of recanalization failure in this study.

Conclusion

Hypertension and the absence of prior intravenous thrombolysis have been found to be significant contributing factors to the high rate of thrombectomy failure in large-vessel occlusion.
