脑干出血只占颅内出血的10％,而中脑出血则更为罕见,我们曾收治3例报告如下。例1.男,14岁,因突然头痛,呕吐,复视,抽搐发作和昏迷来院。查体:T39℃,浅昏迷,瞳孔右:左=4:1.5,光反应(一),左中枢性面瘫,左肢活动差,左巴氏征(+)。浅反射左侧(-),右侧正常。腰穿CSF压力不高,RBC 14.4万/dl。右颈动脉造影见大脑后动脉有动静脉畸形(AVM)。脑室穿刺引流出浅粉色脑脊液,意识障碍有所好转,双眼上下视不能,左上脸下垂,水平眼颤,此后意识又变坏。手术探查在Ⅲ脑室后部实质内清除二块黄豆大小血块,术后多次靠脑室外引流缓解症状,终因脑室感染,病况日渐垂危,自动出院后不久死亡。例2.男,61岁,平素有高血压。因突然心区不适,呕吐、大汗、尿失禁和昏迷而来院。查体:T37.3℃BP26.5/14.5kPa,昏迷,视盘无水肿,瞳孔等大,右鼻 Brainstem hemorrhage accounts for only 10% of intracranial hemorrhage, while the mesolimbic bleeding is even more rare, we have treated 3 cases reported as follows. Example 1. Male, 14 years old, came to hospital due to a sudden headache, vomiting, diplopia, seizures and coma. Physical examination: T39 ℃, shallow coma, pupil right: left = 4: 1.5, light response (a), left central paralysis, left limb activity is poor, left Pakistan’s sign (+). Light reflection left (-), right normal. CSF pressure is not high, RBC 144,000 / dl. Right carotid artery angiography shows posterior cerebral artery arteriovenous malformations (AVMs). Ventricular puncture drainage of light pink cerebrospinal fluid, disturbance of consciousness improved, eyes can not look up and down, drooping left and right face, the level of nystagmus, since then awareness and deterioration. Surgical exploration of the back of the ventricle in the virtual clearance of two pieces of soybeans size of blood clots after multiple drainage by the external drainage to relieve symptoms, the end of the ventricular infection, the condition is increasingly dying, died soon after discharge from the hospital. Example 2. Male, 61 years old, usually have high blood pressure. Due to sudden heart discomfort, vomiting, sweating, urinary incontinence and coma from the hospital. Physical examination: T37.3 ℃ BP26.5 / 14.5kPa, coma, optic disc without edema, pupil and other large, right nose
