显微镜下颈前路经颈椎间隙减压的手术技巧

[摘要]目的探讨显微镜下经椎间隙颈前路减压技术,总结手术技巧。方法2000年6月至2005年12月间于显微镜下共行颈前路经椎间隙减压术271例,均为颈椎间盘突出患者,其中单间隙178例、双间隙71例、三间隙22例。所有患者影像显示脊髓前方压迫、压迫程度轻到中度及轻度髓内改变。主要设备为脊柱外科专用手术显微镜和高速磨钻。高速磨钻磨除纤维环和部分椎体后壁,显露清理变性髓核,钩形剥离子提起后纵韧带后切断,再切除残余的后纵韧带及椎体后缘骨赘。结果271例手术无脊髓、神经、血管损伤并发症。手术时间(62±12.4) min,失血 (126±29.4) ml,下地时间为术后(1.8±0.4) d。所有患者术后神经功能均有不同程度改善,功能改善率优69例,良157例,中27例,差18例。结论经椎间隙减压适用于椎间隙平面的病变,显微镜下精细操作及高速磨钻有利于手术成功,术后椎间隙结构更符合颈椎生物力学特性。     

经椎旁肌间隙入路治疗胸腰椎椎间孔哑铃形肿瘤

目的 探讨经椎旁肌间隙入路切除胸腰椎椎间孔哑铃形肿瘤的手术方法和效果。方法2003年1月至2009年6月共收集胸腰段哑铃形肿瘤患者32例：神经鞘瘤23例,神经纤维瘤6例,神经纤维瘤病3例。手术采用胸腰椎后路经椎旁肌间隙入路,术中分离多裂肌和最长肌间隙,切除关节突关节后,暴露椎间孔内外的肿瘤,完整切除肿瘤。必要时可经椎弓根螺钉内固定和脊柱植骨融合术重建脊柱稳定性。所有患者获得随访。结果 所有肿瘤均全切除,其中23例行内固定重建脊柱稳定性。神经功能均有改善。术后随访8个月至6年,平均32个月。无内固定松动、断裂,无脊柱后凸、侧凸等畸形。结论 以椎间孔及椎间孔外部分为主的腰椎椎间孔哑铃形肿瘤,可采用经椎旁肌间隙入路椎间孔切开切除,必要时用椎弓根螺钉固定、椎间植骨融合,重建脊柱稳定性。此方法具有肿瘤暴露好、术中出血少、术后可早期下床活动、兼顾脊柱稳定性等优点。     

大鼠异体肢体移植术后急性排斥反应阶段血管内皮细胞ICAM-1表达的动态变化

Objective To investigate the dynamic changes of intercellular adhesion molecule-1 (ICAM-1) expression in endothelial cells (EC) during hindlimb allograft acute rejection in rats and the inhibitory effect of cyclospofine A (CsA) on the acute rejection. Methods The rat model of hindlimb allograft was developed. The rats were randomly divided into following groups: control group (Wistar→Wistar), rejection group ( Sprague-Dawley→Wistar) and CsA-treated group (Sprague-Dawley→Wistar). At postoperative day 1, day 4 and day 7samples of the femoral artery from the allograft limb were harvested to observe the pathologic changes. ICAM-1 expression in EC was quantified using immunohistochemical assay. Results Slight swelling and weak ICAM-1expression of EC were observed in the control group. In the rejection groups, obvious EC swelling and massive lymphocyte infiltration were seen. ICAM-1 expression in EC was significantly stronger and elevated. In CsA-group only mild infiltration of lymphocytes was seen and ICAM-I expression in EC was also much weaker.Conclusion During rat hindlimb allograft acute rejection the expression of ICAM-1 in EC was closely related to the occurrence and development of acute rejection. CsA could reduce the expression of ICAM-1 in EC and hence inhibit acute rejection of composite allograft.     

颈椎术后并发急性精神障碍的原因分析及护理对策

手术后急性精神障碍是指在手术后数天内发生,在意识、认知、记忆、定向以及睡眠等方面的紊乱,是一种可逆的、具有波动性的急性精神紊乱综合征,通常又称术后认知障碍、术后谵妄等[1].它可导致康复延迟,并发症和病死率增加,以及住院时间延长和医疗费用增加,而且是术后其他严重并发症的早期症状[2].我院脊柱外科2005年1月-2007年3月共有125例患者在我科接受颈椎前路或者后路手术,其中手术后出现急性精神障碍患者9例,经药物治疗及心理护理后均获痊愈,为探讨颈椎术后并发精神障碍的因素及护理对策,现将患者资料分析如下.

高乌甲素用于病人自控镇痛的效果观察

术后疼痛是围术期诸多重要问题之一,许多研究表明,病人自控镇痛(pa-tient-controlledanalgesia,PCA)不仅能够提供良好的镇痛效果,而且可减少术后有关并发症,有利于病人早期恢复犤1犦。本文以曲马多作为对照,评价高乌甲素应用于静脉病人自控镇痛(PCIA)的临床效果与安全性。现报道如下。1临床资料1.1一般资料:选择择期手术100例,ASAⅠ～Ⅱ;男48例,女52例;年龄18～76岁,平均49±8.4岁。其中双下肢骨折内固定术21例、甲状腺腺癌清扫术16例、乙状结肠、直肠手术28例、妇科手术6例、乳癌根治术27例、胆道手术2例。随机分成两组,Ⅰ组为高乌甲素…     

盐酸乙哌立松联合塞来昔布治疗颈肩腰背痛75例疗效分析

目的评价盐酸乙哌立松联合应用塞来昔布对常见颈肩腰背痛的临床疗效。方法收集150例门诊颈肩腰背痛患者,随机分成单用药组(单独口服塞来昔布)和联合用药组(盐酸乙哌立松联合塞来昔布),采用VAS方法进行疗效评价,并观察2组的不良反应。结果联合用药组的总有效率为84%,显著高于单用药组的65.33%(P<0.05);联合用药组对急慢性颈肩软组织劳损、肩关节周围炎和急慢性腰肌劳损引起疼痛的疗效优于单用药组,但对腰椎间盘突出症引起疼痛的疗效与单用药组相当。2组发生不良反应的患者均为1例(1.33%)。结论盐酸乙哌立松联合塞来昔布治疗颈肩腰背痛可获得较好的镇痛疗效,优于单纯应用塞来昔布胶囊。

基于能谱CT动脉造影的脊髓型颈椎病脊髓前动脉血流灌注特点

目的应用能谱CT动脉造影(CTA)研究健康人群和脊髓型颈椎病(CSM)患者颈椎脊髓前动脉(ASA)的形态和血流灌注特点。方法招募16名健康志愿者为对照组,筛选21例CSM患者为病例组,行能谱CTA检查。获取颈椎ASA重建图像,观察ASA的走行、充盈情况。以各节段ASA平均碘含量代表动脉血流灌注量,比较对照组各节段血流灌注量,计算病例组动脉受压部位的平均血流灌注减少率。结果对照组16例ASA充盈良好,其中13例在C4～6节段观察到脊髓前根动脉分支汇入ASA,自C1至C7 ASA血流灌注较均匀但呈现轻度逐渐增加的趋势。病例组21例中,9例颈椎ASA充盈良好;12例在颈髓受压节段出现ASA充盈减弱,其中4例受压节段以下的动脉充盈不良,其余8例受压节段以下动脉再次充盈,12例的受压处动脉灌注减少率为(28.64±7.73)%(16.86%～38.16%)。21例中有14例ASA在C4～6节段侧方有脊髓前根动脉分支汇入ASA。结论健康状态下颈椎ASA各节段血流灌注较均匀,部分CSM患者中可出现ASA受压,但一般不会发生完全梗阻;由于下颈椎部位脊髓前根动脉分支的汇入,部分ASA受压以下节段可重新充盈。
