大脑前动脉A_1段动脉瘤少见,这个部位的巨型动脉瘤更为罕见。作者报告3例治愈的A_1段巨大动脉瘤,并对有关问题进行了探讨。 例1,女,48岁,因严重的偏头痛及反应迟钝6周就诊。神经系统检查正常,CT扫描示左额叶有一巨大的高密度亚急性血肿块,其边缘有薄层的增强效应;周围有明显的水肿血管造影显示左侧大脑前动脉A_1段有一巨大动脉瘤;MRI显示瘤内有薄壁血栓,周围有水肿带,瘤囊最大直径为34mm,单光子发射CT扫描(SPECT)检查示左额叶有一广泛的高灌注像,神经眼科学检查无异常。例2,女,42岁,以左额部顽固性头痛伴头晕就诊。MRI显示有一直径为32mm的巨大动脉瘤,瘤内壁有薄壁血栓;脑血
A section of anterior cerebral artery aneurysm rare, this site of giant aneurysms is even more rare. The authors report 3 cases of giant aneurysm A_1 healed, and discussed the related issues. Case 1, female, 48 years old, due to severe migraines and unresponsive 6 weeks treatment. Nervous system examination was normal, CT scan showed a large high-density sub-acute hematoma mass in the left frontal lobe with a thin enhancement at the periphery; obvious edema around the angiogram showed a huge aneurysm in the left anterior cerebral artery segment A_1; MRI showed that there was a thin wall thrombus in the tumor with edema around. The maximum diameter of the tumor capsule was 34mm. Single photon emission computed tomography (SPECT) examination showed a wide range of perfusion images in the left frontal lobe. There was no abnormal neuropsychological examination. Example 2, female, 42 years old, with left head stubborn headache with dizziness treatment. MRI showed a huge aneurysm with a diameter of 32 mm, with thin-wall thrombi on the inner wall of the tumor; and cerebral blood
