医疗信息学医疗信息学

背景情况:

机械血栓切除术 (eTICI 2a-2c) 后的不完全再输血呈现出异质的临床过程.
延迟再注血 (DR) 与有利的结果有关,类似于完整的再注血 (TICI 3).

研究的目的:

开发和验证一种预测模型来预测延迟再注射 (DR) 的发生.
帮助医生识别患有血栓切除术后良性自然疾病进展的患者.

主要方法:

连续进行血栓切除术的患者的单中心注册分析 (02/2015-12/2021).
变量选择使用启动后的循序渐进逆向逻辑回归.
使用随机森林分类算法和内部验证的模型开发.

主要成果:

预测模型显示了足够的区分能力 (C-统计值0.79).
主要预测DR的因素包括心房动,更长的干预到后续时间,eTICI得分和抵押状况.
该模型可能会在25%的自发性DR患者中减少不必要的重复干预.

结论:

开发的模型提供了不完整的血栓切除术后DR的合理预测准确度.
根据预测的自然疾病进展,对进一步的再输血尝试做出明智的治疗决策.

Ischemic Stroke ll: Pathophysiology

Ischemic Stroke ll: Pathophysiology

An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...
