摘要
目的探讨蛛网膜下腔出血(SAH)合并硬膜下血肿(SDH)的临床特点和机理。方法对16例经CT、脑血管造影、手术和11例尸解证实的颅内动脉瘤破裂致SAH合并SDH患者进行临床及病理特点分析。结果临床表现意识障碍12例,玻璃体下出血7例,死亡13例。导致SAH合并SDH的原因可能为:(1)动脉瘤破裂,大量血液破入蛛网膜下腔,撕破蛛网膜;(2)伴随的脑内血肿破入蛛网膜下腔并撕破蛛网膜;(3)发病时突发意识丧失、摔倒,致头部外伤。结论颅内动脉瘤致SAH可合并SDH,其预后不佳,病死率高,CT阴性者不能完全排除合并SDH的可能。
Objective To study the clinical characteristics and pathogenic mechanism of subarachnoid hemorrhage(SAH) complicating subdural hematoma(SDH). Methods 16 cases by CT,cerebral angiography,operation and 11 autopsy that were evaluated as the patients with SAH complicating SDH were carried out clinical and pathological feature analyses.Results 12 cases of unconsciousness and 7 cases of subhyaloid hemorrhages were observed,and 13 cases of death.The causes of SAH complicating SDH may be:(1)After intracranial aneurysm rupture,large amounts of blood flow into subarachnoid space and da mage arachnoid membrane,(2)Accompanying brain parenchymehematoma ruptures into the subarachnoid cavity,and damage arachnoid membrane.(3)At the onset a sudden loss of consciousness ,dropping and caused head injury.Conclusion Aneurysmal SAH might complicate SDH,it had poor prognosis and high mortality.CT negative image could not be excluded the diagnosis of SDH.
