Đặc điểm vi xuất huyết não và nguy cơ chuyển dạng xuất huyết ở bệnh nhân nhồi máu não cấp có điều trị tái thông

Abstract

Objective: Evaluate the characteristics of cerebral microbleeds and factors related to hemorrhagic transformation in patients with acute cerebral infarction undergoing revascularization treatment at University Medical Center, Ho Chi Minh City. Subjects and methods: Cross-sectional descriptive study combined with medical record monitoring on 79 patients diagnosed with acute cerebral infarction who were admitted and treated at the Department of Neurology, University Medical Center, Ho Chi Minh City. Results: Patients with microhemorrhage (VXH) accounted for 37.97%. The number of 1-4 VXH accounted for the highest rate of 31.65%, only 01 case had more than 10 VXH, accounting for 1.27% %. The location of social lesions is mainly in the deep brain area, accounting for 21.52%. There is an association between VXH and dyslipidemia with p = 0.16 (OR 4.12, CL 1.14-18.47), white matter pathology according to Fazekas classification with p = 0.041. The main complications of hemorrhagic transformation after revascularization are HI, accounting for 26.58%, followed by PH, accounting for 6.33%, and ICH+, accounting for 3.8%. There is an association between Glasgow scale (OR = 1.66, CI 0.79 - 3.51) with symptomatic ICH and PH with p < 0.05. Found an association between NIHSS Scale and ICH with p = 0.037 (OR = 5.46 CI 1.10 – 19.00). There is not enough evidence to conclude about the relationship between the number and location of microbleeds and complications of hemorrhagic transformation after revascularization. Conclusion: VXH is not a factor to delay recanalization interventions in acute myocardial infarction patients with indications for intervention. Patients at high risk of multiple VHs should have an MRI scan before intervention.
