床突旁动脉瘤起自颈内动脉近环至后交通动脉起始部之间。采用颅底入路,自硬膜外或/和硬膜下切除前床突、视柱,切开镰状韧带,打开视神经管,必要时切开颈内动脉远环及硬膜袖是显露床突旁动脉瘤,实施颅内近端控制的关键。术中需根据动脉瘤的位置、瘤颈的宽度及粥样硬化和钙化的程度、动脉瘤与周围结构的关系等因素决定治疗方案。术后主要的并发症是神经损伤和缺血性脑梗死。
Para-bedside para-aortic aneurysm arises from the proximal internal carotid artery to the beginning of the posterior communicating artery. Craniofacial approach was used to remove the anterior and / or subdural anterior bed buccal and visual columns and the sickle ligament was opened to open the optic canal and, if necessary, to open the internal carotid artery distal and epidural sleeves to reveal the bed Para-aortic aneurysm, the key to the implementation of intracranial proximal control. Intraoperative need to be based on the location of the aneurysm, tumor neck width and degree of atherosclerosis and calcification, aneurysm and the surrounding structure and other factors determine the treatment options. The main postoperative complications are nerve damage and ischemic stroke.
