本文报告49例颅内动脉瘤破裂造成蛛网膜下腔出血的CT材料。男12例,女37例。年龄35～76岁(平均54岁)。CT检查时间为出血后90～30天。49例中40例增强前见出血,占82%。由出血部位估计动脉瘤的位置:纵裂血多,提示在大脑前动脉,准确率为92%;外侧裂血多,提示在中动脉,准确率为70%;血液较广泛分布于脑池,但两侧稍不称,伴纵裂小量出血,提示一侧颈内动脉动脉瘤,为47%;广泛、对称脑池出血则动脉瘤位置不明,本文6例,有2例中动脉动脉瘤,4侧颈内动脉瘤;后颅窝脑池血多,提示幕下动脉瘤破裂。局限脑内血肿12例准确诊断动脉瘤位置11例。27例增强检查中的8例(30%)看到动脉瘤,21例有蛛网膜下
This article reports 49 cases of intracranial aneurysm rupture caused by subarachnoid hemorrhage CT material. There were 12 males and 37 females. Age 35 to 76 years (mean 54 years). CT examination time for 90 to 30 days after bleeding. Bleeding was seen in 40 of 49 cases, accounting for 82%. The location of the aneurysm estimated by the site of bleeding: longitudinal cracked blood, suggesting that the anterior cerebral artery, the accuracy rate was 92%; lateral fleck, suggesting that in the middle artery, the accuracy rate of 70%; blood is more widely distributed in the cerebral pool, But a little less on both sides, with a small amount of longitudinal hemorrhage, suggesting that one side of the internal carotid artery aneurysms, 47%; extensive, symmetrical cerebral pool hemorrhage aneurysm is unknown, 6 cases, 2 cases of middle artery aneurysm , 4-sided carotid aneurysm; posterior fossa brain pool more blood, suggesting aneurysm rupture under the screen. 12 cases of intracerebral hemorrhage in the diagnosis of aneurysms accurate diagnosis of 11 cases. Aneurysms were seen in 8 of 27 patients (30%) and in 21 patients subarachnoid
