简介:目的探讨椎管内肿瘤的临床诊断与显微外科治疗方法。方法回顾性分析30例椎管内肿瘤患者的临床资料。结果术后病理检查证实:神经鞘瘤14例,神经纤维瘤8例,脊膜瘤4例,室管膜瘤、畸胎瘤、蛛网膜囊肿、胶质瘤各1例。肿瘤位于颈段15例,胸段9例,腰段5例,骶尾段1例。硬脊膜外肿瘤5例,髓外硬脊膜下22例,髓内3例。肿瘤全切23例(其中髓外肿瘤全切22例,髓内肿瘤全切1例),部分切除7例。出院时29例患者肌力得到明显恢复,20例肢体感觉障碍明显好转,1例症状加重。结论椎管内肿瘤大多为良性肿瘤,手术效果较好,宜早诊断、早手术。MRI检查和显微外科手术可极大地提高手术的疗效。
简介:目的探讨自发性脑出血30d预后的影响因素,建立预测模型,为临床诊治提供客观依据.方法回顾收集了300例自发性脑出血患者,对其临床及影像学特点进行详细的记录.通过单因素分析,找出与30d预后相关的指标,再进行多因素Iogistic回归分析,得出回归方程.结果Logistic回归分析筛选出5项影响30d病死率的独立预测因素,分别是:Glasgow昏迷量表(GCS)评分(X8,OR2.046,95%C/1.138~5.679)、美国国立卫生院卒中量表(NIHSS)评分(X15,OR2.590,95%C/1.226~5.470)、并发症(X16,OR4.820,95%C/1.877/~12.377)、吞咽障碍(X17,OR7.912,95%C/1.280~48.901)和中线移位(X22,OR13.969,95%C/4.760~40.990).回归方程为:Logit(p)=-12.005+0.716X8+0.952X15+1.573X16+2.068X17+2.657X22,该模型的判断正确率为87.5%.结论GCS评分、NIHSS评分、并发症、吞咽障碍和中线移位可作为判断自发性脑出血患者30d病死率的重要预测因素.
简介:目的探讨鞍结节脑膜瘤显微手术治疗效果。方法对30例行显微手术治疗的鞍结节脑膜瘤患者的临床资料及手术效果进行分析总结。结果肿瘤全切(Simpon分级Ⅰ、Ⅱ级)24例,次全切(Simpon分级Ⅳ级)4例,大部分切除2例。术中去骨瓣减压2例。手术死亡1例。术前有视力下降的26例患者中,术后早期视力改善20例,无变化4例,恶化2例。术后随访3~38个月,2例术中去骨瓣减压的患者分别于术后6个月及8个月时行颅骨缺损修补术;24例肿瘤全切病例中,3例患者有肿瘤复发,2例行二次手术,1例选择放射治疗。失访3例。结论鞍结节脑膜瘤位置深在,与周围血管神经等重要结构关系密切,但积极的显微外科手术治疗效果良好。
简介:目的探讨天眩清治疗椎-基底动脉缺血性眩晕的疗效.方法采用天眩清0.6每日1次静点,与对照组应用复方丹参20ml静点做疗效对比,结果采用卡方检验.结果治疗组疗效优于对照组,两组显效率有权显著性差异(P<0.005),总有效率有显著性差异(P<0.01).结论天眩清治疗椎-基底动脉供血不全疗效显著无明显不良反应,值得临床推广应用.
简介:目的:探讨重复经颅磁刺激(rTMS)治疗非器质性失眠症的临床疗效。方法:根据ICD-10,选择非器质性失眠症患者60例,随机分为治疗组与对照组各30例,治疗组使用rTMS治疗(刺激部位为右侧前额叶背外侧区,刺激频率1Hz,刺激强度为运动阈值的100%,刺激时间50s,刺激间歇5s,连续刺激1500次),对照组使用伪刺激治疗(刺激部位、频率、时间、间歇、次数都同治疗组,有振动声音,但不产生磁场效应),2组均1次/d,连续2周。对2组治疗前后的匹兹堡睡眠质量指数量表(PSQI)及多导睡眠监测(PSG)的结果进行比较。结果:治疗组患者经rTMS治疗后匹兹堡睡眠质量指数量表得分明显低于治疗前;多导睡眠监测显示睡眠潜伏期、觉醒次数及觉醒时间均明显少于治疗前与对照组(P〈0.01)。结论:rTMS可有效缩短入睡潜伏期,减少觉醒次数并缩短觉醒时间,延长深睡眠时间,可改善睡眠结构,提高患者的睡眠质量,rTMS治疗非器质性失眠症疗效可靠。
