急性颅高压缺血缺氧性脑损伤致脑死亡CTA二例并文献复习

Two Cases of CTA for Brain Death Caused by Acute Intracranial Hypertension with Hypoxic-ischemic Brain Injury and Literature Review

急性颅高压缺血缺氧性脑损伤属急性神经重症,需准确地对脑损伤程度进行判定和及时救治,易进展为脑死亡,CTA是临床中评估脑血管形态和脑血流变化的重要依据。本文报告2例应用CTA成像技术显示颅内供血情况改变的急性颅高压缺血缺氧性脑损伤且满足临床脑死亡评估标准的患者临床资料,并分别在中国知网和PubMed上以“急性颅高压”“急性脑损伤”“缺血缺氧性脑损伤”“脑死亡”“CTA”和“Acute intracranial hypertension”“Acute brain injury”“Hypoxicischemic brain injury”“Brain death”“CTA”为关键词进行文献检索和讨论,以期为该类患者病情的临床诊断和治疗提供参考。

Acute intracranial hypertension with hypoxic-ischemia brain injury is a severe neurological disease.It is necessary to accurately determine the degree of brain injury and treat it in time,and it is easy to progress to brain death.CTA is an important basis to evaluating the changes of cerebrovascular morphology and cerebral blood flow in clinical practice.This paper reports the clinical data of two patients with acute intracranial hypertension and hypoxic-ischemic brain injury with changes in intracranial blood supply using CTA imaging technology,and met the clinical evaluation criteria for brain death.Literature searches and discussions were conducted on CNKI and PubMed with the keywords of"acute intracranial hypertension","acute brain injury","hypoxic-ischemic brain injury",and"CTA",in order to provide reference for the clinical diagnosis and treatment of this kind of patients.
