脑微出血与卒中相关性研究进展

脑微出血是脑小血管病的重要影像学表现之一,目前检出率随着影像学技术的进步而显著提升。研究显示脑微出血可能与缺血性卒中和脑出血风险增加相关,对未来卒中发生、发展具有一定预测价值,有助于指导卒中高危人群筛查及防治。脑微出血是否增加抗栓治疗后出血转化风险,以及相应风险是否与抗栓治疗获益相抵,目前仍有争议,是亟待解决的临床难题。临床工作中应综合评估抗栓治疗的预防获益及出血风险,以制订合理的治疗策略。

Progress in the Correlation between Cerebral Microbleeds and Stroke

Cerebral microbleeds (CMBs) is one of the important imaging features of cerebral
small vessel disease, and their detection rate increases significantly with the progress of imaging
technology. Studies have shown that CMBs may be associated with the increased risk of ischemic
stroke and cerebral hemorrhage, so CMBs maybe have certain predictive value for the occurrence
and development of future stroke, which can help guide the screening and prevention of high-risk
population of stroke. Whether CMBs can increase the risk of hemorrhagic transformation after
antithrombotic therapy and whether this risk can offset the benefit of antithrombotic therapy are still
controversial, which is an urgent clinical problem to be solved. In clinical practice, the prevention
benefit and bleeding risk of antithrombotic therapy should be comprehensively evaluated so as to
make reasonable and individualized treatment strategy.
