1980年5月～1994年4月经治颅内动脉瘤134例,其中大脑中动脉动脉瘤(MCAA)21例占15.7％,男10例、女11例,平均年龄48.1岁。21例以蛛网膜下腔出血(SAH)发病,18例有暂短意识障碍,其中3例不久陷入深昏迷,4例意识逐渐恶化,此7例均有继发颅内血肿。CT显示SAH外侧裂池积血呈孤形是其重要特点。出血量较大可扩散到终板池、交叉池、脚间池及对侧侧裂池等。7例脑内血肿2例位于颞叶,5例位于颞叶深部,达基底节区,其中2例破入脑室。脑血管造影是诊断MCAA的主要手段,本组21例发现MCAA23个,其中多发动脉瘤7例占33.33％。18例取手术治疗,采用Yasargil入路,手术死亡1例。另外,本组造影死亡2例,共3例。
From May 1980 to April 1994, 134 cases of intracranial aneurysms were treated, including 21 cases of middle cerebral artery aneurysm (MCAA) accounting for 15.7%, 10 males and 11 females, with an average age of 48.1 years. Of the 21 patients who developed subarachnoid hemorrhage (SAH), 18 had short-term unconsciousness. Three of them developed deep coma and their consciousness gradually deteriorated. All seven had secondary intracranial hematoma. CT showed that the solitary hemorrhagic solitary hemorrhage in SAH is an important feature. Large amount of bleeding can spread to the end plate pool, cross pool, foot pool and the opposite side of the pool and so on. Seven cases of intracerebral hematoma located in the temporal lobe, five cases located in the deep temporal lobe, up to the basal ganglia, two of which broke into the ventricle. Cerebral angiography is the main means of diagnosis of MCAA, 21 cases of this group found 23 MCAA, including multiple aneurysms in 33.33%. Eighteen patients were surgically treated with Yasargil and one patient died of surgery. In addition, the group angiography death in 2 cases, a total of 3 cases.
