简介:摘要目的探讨Hybrid手术(颈椎人工椎间盘联合零切迹融合器)治疗多节段脊髓型颈椎病(MCSM)的临床疗效。方法回顾性分析2017年3月至2019年10月山西医科大学第一医院神经外科采用显微镜下Hybrid手术治疗的16例MCSM患者的临床资料,观察术后并发症,术后6和12个月进行临床和影像学随访。采用视觉模拟疼痛评分(VAS)、日本骨科协会(JOA)颈椎评分、Oswestry功能障碍指数(ODI)、改良MacNab临床疗效评价标准评估手术疗效。行影像学检查评估患者的颈椎人工椎间盘节段的椎间隙高度、活动度以及Cobb角;检查颈椎人工椎间盘的位置及零切迹融合器有无松动、滑脱、移位等;采用Bridwell标准判断零切迹融合器的融合情况;采用Kellgren分级标准判断颈椎人工椎间盘邻近节段的退变情况。结果16例患者共应用32个零切迹融合器和16个人工椎间盘。术后复查X线片均显示颈椎人工椎间盘及零切迹融合器位置良好。术后出现吞咽困难3例,声音嘶哑2例。16例患者均完成随访。随着时间延长,16例患者的VAS和ODI均呈下降趋势,JOA评分呈上升趋势,颈椎Cobb角的角度呈增加趋势(均P<0.01);而手术前、后颈椎人工椎间盘节段的椎间隙高度和活动度的差异均无统计学意义(均P>0.05)。12个月随访时,改良MacNab评价结果为优9例,良4例,可3例,优良比例为13 ∶16;无一例出现颈椎人工椎间盘或融合器松动、滑脱、移位等情况;32个应用零切迹融合器的手术节段中,Bridwell分级Ⅰ级融合25个节段,Ⅱ级融合7个节段;颈椎人工椎间盘邻近节段Kellgren分级Ⅰ级退变1例,Ⅱ级退变2例;16例患者均未见明显的异位骨化。结论Hybrid手术治疗MCSM的临床疗效较好,可部分保留颈椎活动度,减少邻近椎体退变的发生,同时取得良好的减压和稳定效果。

简介:摘要目的研究对颅内复杂动脉瘤疾病接受Hybrid手术患者,科室在治疗期间加强围手术期整体护理干预措施的影响。方法将我院于2015.1月-2016.2月间收治37例颅内复杂动脉瘤患者,科室为患者提供围手术期优质护理干预措施,评价患者术后恢复情况。结果37例颅内复杂动脉瘤患者,术后经围手术期整体护理干预后,患者出现并发症情况水电解质紊乱4例、肺部感染2例,经治疗后痊愈出院,未发生再出血情况。结论护士为颅内复杂性动脉瘤患者提供Hybrid手术治疗期间,护士为患者提供围手术期整体护理干预措施,可有效促进患者术后康复,减少术后并发症发生率,此种护理模式与患者术后康复存在积极意义,值得临床推广。
