脑出血早期血肿扩大影像学特征研究进展

Research progress in the imaging characteristics of early hematoma expansion in cerebral hemorrhage

脑出血是一种破坏性的神经系统疾病,占所有脑卒中的10%~30%,是所有脑卒中亚型中病死率最高的疾病之一。其中再出血是脑出血继发性损伤最主要因素之一。及时诊断并预防血肿扩大对改善脑出血预后、降低病死率具有重要意义。本文从影像学特征方面综述预测早期血肿扩大的研究进展,为治疗脑出血和评估患者预后提供参考。

Intracerebral hemorrhage is a destructive neurological disease,accounting for 10%to 30%of stroke patients and presenting the highest mortality among stroke patients.Early hematoma expansion is one of the most serious factors for secondary injury of intracerebral hemorrhage.The prevention of hematoma enlargement is of great significance to improve the prognosis of intracerebral hemorrhage and to reduce mortality.This article summarizes the early hematoma expansion signs from the computed tomography characteristics,and provides a reference for the treatment and prognosis evaluation of patients.
