颅内巨大动脉瘤的治疗常常是困难的。其治疗方法有:1.钳闭瘤蒂;2.将邻近的营养血管阻断;3.联合近端血管结扎与远端血管通过颅内、外分流的成形术。有些直径大于2.5cm属巨大动脉瘤,由于它们的形态特点,蒂部不能直接夹闭。若用近端动脉的梗阻术,又可导致缺血的并发症,治疗较困难。作者成功地治疗一例14岁男孩,左侧大脑中动脉处有一个罕见的巨大的螺旋状动脉瘤,几乎占据了颅腔穹隆的20％。患儿入院时体查无神经系统损害症状,眼底伴有轻度水肿。脑血管证实左侧大脑中动脉有一个具有部分性血栓的巨大动脉瘤。将CT和MRI检查的结果进行三维空间及容积分析,该动脉瘤容积为186.8ml。手术方法分两步,第一步把动脉远端的分支与左颞上动脉吻合,颅内、
Treatment of intracranial giant aneurysms is often difficult. The treatment methods are: 1. Closing tumor pedicle; 2. Will be adjacent to the nutrient vessels blocked; 3. Joint proximal vascular ligation and distal blood vessels through the intracranial and external shunt angioplasty. Some diameter larger than 2.5cm is a huge aneurysm, because of their morphological characteristics, pedicle can not be directly clipped. If the use of proximal artery obstruction, but also lead to ischemic complications, treatment more difficult. The authors successfully treated a 14-year-old boy with a rare giant helical aneurysm at the left middle cerebral artery that occupied almost 20% of the dome of the cranial cavity. Children admitted to hospital without physical damage symptoms, fundus associated with mild edema. Cerebral blood vessels confirmed that there was a giant aneurysm with a partial thrombus in the left middle cerebral artery. Three-dimensional space and volume analysis were performed on the results of CT and MRI examinations. The aneurysm volume was 186.8 ml. Surgical methods are divided into two steps, the first step of the distal branch of the artery and the left superior temporal artery anastomosis, intracranial,
