摘要
目的探讨基底动脉动脉瘤的临床特点和病理改变。方法回顾性分析4例基底动脉动脉瘤患者的临床资料及脑局部解剖结果。结果4例均急性起病,出现昏迷、脑膜刺激征阳性、眼球运动障碍,3例血压明显升高,2例出现偏瘫,全部死于脑疝。尸解见基底动脉主干梭形动脉瘤3例、基底动脉分叉部囊状动脉瘤1例,均有动脉瘤破裂、蛛网膜下腔出血(SAH),以及脑组织肿胀、坏死、软化、胶质增生等。结论高血压可能为引起基底动脉动脉瘤破裂的首要原因,基底动脉动脉瘤破裂时主要表现SAH的症状和体征,预后极差,脑疝是其主要的死亡原因。
Objective To discuss the clinical characteristics and pathological changes of basilar artery aneurysm. Methods The clinical materials and brain topography results were analyzed retrospectively in 4 patients with basilar artery, aneurysm. Results The onsets of disease in all cases were acute and common manifestations were coma, positive meningeal irritation sign and ocular dyskinesis. 3 cases showed hypertention, 2 cases presented with hemiparalysis, all cases died of herniation. 3 cases of basilar artery trunk fusifornl aneurysm and 1 case of basilar artery furcation saccular aneurysm were detected in autopsy. There were aneurysm rupture, subarachnoid hemorrhage and swell, necrosis, softening, gliosis of brain tissue confirmed pathologically in all cases. Conclusion Hypertension is probably the most important cause of aneurysm rupture. Signs and symptoms of subarachnoid are the most common manifestation when basilar artery aneurysm ruptures with poor prognosis. Herniation is the main cause of death.
