颅内动脉瘤手术中破裂的发生率在7～51％,可发生于从麻醉至夹闭瘤颈的任何阶段,但大多发生于分离动脉瘤颈和夹闭瘤颈时。动脉瘤破裂的部位多发生于瘤壁上的薄弱处或原有瘤囊与新形成的瘤囊交界处。从手术一开始就应采取措施防止破裂,包括低血压麻醉,暂时性控制载瘤动脉和显微技术。对低血压和暂时夹闭动脉的优缺点作了比较。为防止脑缺血,用体感诱发电位监测是一种可靠的方法。
The incidence of intracranial aneurysm rupture during surgery is 7 to 51%, which can occur at any stage from anesthesia to clamping of the neck, but mostly occurs when the aneurysm neck is isolated and the neck is clamped. The site of rupture of the aneurysm mostly occurs in the weak part of the tumor wall or the junction of the original tumor capsule and the newly formed tumor capsule. From the outset of surgery, measures should be taken to prevent rupture, including hypotensive anesthesia, temporary control of parent artery, and microscopy. The advantages and disadvantages of hypotension and temporary clipping of the arteries were compared. To prevent cerebral ischemia, somatosensory evoked potential monitoring is a reliable method.
