脑血管畸形是人的先天性脑血管疾病,是指脑血管发育障碍引起脑局部血管数量和结构异常,并对正常脑血流产生影响。[1]分为脑动静脉畸形、海绵状血管瘤、毛血管扩张、静脉畸形,主要表现有头痛、癫痫和脑出血。本病发生率十万分之二,这种疾病主要危险是畸形血管破裂发生脑出血,其后果轻者致残,重者死亡。法医学鉴定中偶尔会碰到脑血管畸形患者受伤后突发出血猝死的案件,伤病关系常引起争议。作者在检案工作中遇2例,现予以报道。
Cerebrovascular malformations are human congenital cerebrovascular diseases, which refers to the cerebrovascular developmental disorders that cause the number and structural abnormalities of local cerebral blood vessels and affect the normal cerebral blood flow. [1] Divided into cerebral arteriovenous malformations, cavernous hemangiomas, capillary vasodilation, venous malformations, the main manifestations of headache, epilepsy and cerebral hemorrhage. The incidence of the disease two hundred thousandths, the main risk of this disease is the occurrence of cerebral hemorrhage due to ruptured vascular rupture, the consequences of light disability, severe cases of death. Forensic identification occasionally encounter cerebrovascular malformations in patients with sudden death after sudden bleeding cases, the relationship between injuries often controversial. The author encountered two cases in the prosecution work, is to be reported.
