患者女性,28岁,两年内两次因突发头晕、头痛、呕吐,自闻颅内杂音住院。腰椎穿刺可见肉眼血性脑脊液,诊断:“蛛网膜下腔出血”。经药物治疗,上述症状消失出院。本次人院查体无明显神经系统体征。头颅CT检查表现:枕区有大片不规则团块样、条索样高密度区,有的呈蚯蚓样。右颈总动脉造影显示:右侧大脑中动脉侧裂段明显增粗,其远端呈一团块样不规则型造影剂团块形,并可见粗大引流静脉显影。右侧大脑前动脉未见显影,提示右顶颞枕区动静脉畸形。经颅多普勒超声检查;有中动脉在门深45mm～56mm处显示为朝向探头和背离探头的不规则的(毛刺状)增宽的异常血流频谱,血流速度增高,尤以舒张期显著,PI=0.23～0.34,血流声频信号洪大,粗糙,紊乱。右前动脉血流方向逆转,
Female patient, 28 years old, twice within two years due to sudden dizziness, headache, vomiting, self-smell intracranial murmur hospitalization. Lumbar puncture visible naked eye bloody cerebrospinal fluid, diagnosis: “subarachnoid hemorrhage.” After drug treatment, the above symptoms disappear from hospital. This hospital examination no obvious signs of nervous system. Head CT examination showed: pillow area has a large irregular clumps like, cord-like high-density area, some were earthworm-like. Right common carotid artery angiography showed: the right middle cerebral artery segment was significantly thicker at the distal end of a mass of irregular mass-like contrast agent block, and the visible drainage of the venous drainage. Right anterior cerebral artery was not developed, suggesting that the right top temporal occipital arteriovenous malformations. Transcranial Doppler echocardiography; middle artery at the door depth 45mm ~ 56mm at the probe and probe away from the irregular (burr-shaped) broaden the abnormal blood flow spectrum, increased blood flow, especially in diastolic Significantly, PI = 0.23 ~ 0.34, blood flow audio signal flood, rough, disorder. Right anterior artery blood flow reversed,
