Abstract：
The most common manifestation of brain arteriovenous malformations (BAVM) is intracranial hemorrhage. The incidence of ruptured BAVM is 3.5 per 100,000 people per year. The mortality rate of ruptured BAVM within 1 month after diagnosis was 12.7%. Spontaneous thrombosis occurs in less than 1.5% of ruptured BAVMs. This phenomenon was still elusive. Up until now, the gold standard of imaging examination has been cerebral digital subtraction angiography (DSA), whose sensitivity and specificity reach 100%. We reported the spontaneous thrombosis of a ruptured deep BAVM. An 18-year-old woman presented with severe headache and vomiting. The patient also complained of seizures. There was no body weakness, skewed face, or slurred speech. Cerebral computed tomography (CT) showed extensive hemorrhage in the ventricular system and subarachnoid space. Cerebral DSA showed a left subcortical BAVM and was found to have spontaneous thrombosis 3 weeks later when the patient was about to be embolized. Spontaneous thrombosis of ruptured BAVM may occur after intracranial hemorrhage. In this patient, spontaneous thrombosis occurred within 3 weeks.
摘要：
脑动静脉畸形（BAVM）最常见的表现是颅内出血。BAVM破裂的发生率为每年每100,000人中3.5人。诊断后1个月内破裂的BAVM死亡率为12.7%。自发性血栓形成发生在少于1.5％的BAVM破裂中。这种现象仍然难以捉摸。直到现在,影像学检查的金标准是脑数字减影血管造影(DSA),其敏感性和特异性达到100%。我们报道了深BAVM破裂的自发性血栓形成。一名18岁妇女出现严重头痛和呕吐。患者还抱怨癫痫发作。没有身体虚弱，歪斜的脸,或者口齿不清。脑计算机断层扫描（CT）显示心室系统和蛛网膜下腔大量出血。脑DSA显示左侧皮质下BAVM，并在患者即将栓塞3周后发现自发性血栓形成。颅内出血后可能发生BAVM破裂的自发性血栓形成。在这个病人身上,3周内发生自发性血栓形成。
