急性多灶性脑出血52例临床分析

目的：探讨多灶性脑出血（AMCH）的临床特征、发病机理及预后。方法：分析52例AMCH患者的临床资料。结果：52例AMCH占同期脑内出血的8.0%,其中43例（82.7%)有高血压病史,其次为动脉瘤、AVM和脑动脉淀粉样变。依出血部位分幕上型16例,幕下型6例,混合型30例,幕上型死亡率为12.5%,幕下型及混合型死亡率为55.6%。结论：AMCH发病率低,高血压是其最常见原因。凡有幕下后颅窝出血者预后多凶险。

Clinical Analysis of Acute Multifocal Cerebral Hemorrhage in 52 Cases

To study the clinical characteristics, pathogenesis, and prognosis of acute multifocal cerebral hemorrhage. Methods: Clinical data of 52 cases with acute multifocal cerebral hemorrhage were analyzed. Results: Acute multifocal cerebral hemorrhage was 0.8% in all cerebral hemorrhage patients during the same period, 43 patients had hypertension history, others had aneurysms, arteriovenous malformation, and cerebral amyloid angiopathy. According to hemorrhagic region, the hemorrhage classified upper tentorium type (16 cases), lower tentorium type (6 cases), and mixed type(30 cases). The mortality of upper tentorium type was 12.5% ,55.6% in lower tentorium and mixed type. Conclusion: The morbidity of acute multifocal cerebral hemorrhage is low, and hypertension is the most frequent cause. It is dangerous for hemorrhage in posterior cranial fossa.
