Abstract

Objective: Predicting factors that increase the risk of hemorrhagic transformation in patients with large-scale cerebral infarction due to occlusion of the middle cerebral artery undergoing mechanical thrombectomy helps to adjust the appropriate treatment strategy, minimizing the risk of complications after intervention. The study was conducted to describe the predictive ability of the HTI score in predicting hemorrhagic transformation. Method: Retrospective descriptive study on patients with large-scale cerebral infarction due to occlusion of the middle cerebral artery undergoing mechanical thrombectomy at the Stroke Center - Bach Mai Hospital from July 2023 to March 2024. Results:  115 patients were involved in this study in which the male/female ratio was 1.5/1, the age group of 60 - 80 years old was majority with 55.7%. The rate of hemorrhagic transformation was 47%. The median HTI score: 2 points (quartile: 1-3), highest was 5 points, lowest was 0 points. ASPECT score, NIHSS score accounted for the majority of the score composition with a rate of over 30%. HTI score had low predictive ability with AUC: 0.55 with p = 0.36. Conclusion: The rate of hemorrhagic transformation in patients with large cerebral infarction due to occlusion of the middle cerebral artery undergoing mechanical thrombectomy was relatively high. HTI score showed low predictive value in this group of subjects.
