1、颅底肿瘤术后脑脊液中ET.1,NO的动态变化以及影像学特征与脑血管痉挛的相关性研究摘要目的:探讨颅底肿瘤术后脑脊液中内皮素.1(ET.1)、一氧化氮(No)的动态变化以及影像学特征与术后脑血管痉挛(CVS)发生的关系;方法:选择诊断明确的颅底肿瘤病人33例,术中、术后留取脑脊液标本,测定脑脊液中ET一1,NO的含量;同时行经颅超声多普勒(TCD)检查以判定CVS。术前、术后行影像学资料分析。结果:颅底肿瘤术后发生CVS的病人第3天脑脊液中ET.1水平即有明显升高,第7天达到高峰,而后逐渐下降,CVS组ET-1水平明显高于未痉挛组
2、(P<0.05),症状性CVS组ET.1水平高于无症状CVS组(尸3、大血管的关系以及术后蛛网膜下腔出血与术后CVS发生关系密切,鞍区肿瘤与桥小脑角区肿瘤比较术后易发生CVS(Fisher确切概率法,P<0.05)。肿瘤包绕、挤压颅底大血管者与无明显大血管包绕者比较术后易发生CVS(Fisher确切概率法,P<0.05)。术后CT示发生蛛网膜下腔出血者与未发生蛛网膜下腔出血者比较易发生CVS(Fisher确切概率法,P<0.05)。结论:颅底肿瘤术后患者脑脊液中ET.1水平的升高和NO水平的降低参与了术后CVS的发生,其含量与病情演变、CVS程度有关。脑脊液中ET—l水IU平的变化与TCD监测的M4、CAMFV呈正相关,与术后CVS的发生呈正相关,脑脊液中NO水平的变化与TCD监测的MCAMFV呈负相关,与术后CVS的发生呈负相关,两者可预测CVS的严重程度和判断预后。肿瘤生长部位、与大血管的关系以及术后蛛网膜下腔出血与术后CVS发生关系密切,肿瘤直径与术后CVS发生无明显相关性。关键词:颅底肿瘤:脑脊液;内皮素.1;一氧化氮;经颅超声多普勒:脑血管痉挛IVTherelationshipbetweenthedynamicchangesofET一1,NOlevelsinCSF,Imagingfeaturesandcerebra5、lvasospasmafterskullbasetumorresectionAbstractObjective:ToevaluatetherelationshipbetweenthedynamicchangesofEl"-1,NOlevelsinCSF,imagingfeaturesandcerebralvasospasmafterskullbasetumorresectionMethods:ET-1andNOlevelsinCSFweremeasuredin33patientswhichdiagnosedclearlyfrom6、admissionandthepatientsweremonitoredbyTCDtoevaluateCVSbeforeandafteroperation.Thepreoperativeandpostoperativeimagedataswereanalysed.Results:Afteroperation,CSFET一1levelsmarkedlyelevatedinpatientswithCVSonday3,andreachedthepeaksonday7,thendecreasedgradually,CSFET一1leve7、lsinCVSgroupsweresignificantlyhigherthanthosewithoutCVSgroups(P8、ally,CSFNOlevelsinCVSgroupsweresignificantlylowerthanthosewithoutCVSgroups(P<0.05),clinicalCVSgroupswerelowerthanthoseofasymptomati
