蛛网膜下腔出血

定义

蛛网膜下腔出血引起的急性神经功能紊乱。 蛛网膜下腔出血（SAH）指血液积聚于脑部蛛网膜与软脑膜之间的间隙，即蛛网膜下腔。该病表现为急性神经功能障碍，常为毁灭性临床事件，伴有显著死亡率及高存活者发病率。其典型表现为突发性剧烈头痛，患者常描述为“有生以来最剧烈的头痛”。蛛网膜下腔出血的病因可分为非创伤性（约85%由动脉瘤破裂引起）与创伤性两类。 本分类仅适用于非创伤性蛛网膜下腔出血。

Subarachnoid hemorrhage (SAH) is defined as the accumulation of blood in the space between the arachnoid membrane and the pia mater around the brain, referred to as the subarachnoid space. SAH demonstrates as acute neurological dysfunction, and is often a devastating clinical event with substantial mortality and high morbidity among survivors. The classic presentation is often a sudden-onset, severe headache typically described as the "worst headache of my life". The etiology of SAH can be either nontraumatic (about 85% are secondary to aneurysm rupture) or traumatic in nature. This category is intended only for nontraumatic SAH.
