  • 简介:目的了解神经内镜经鼻入路至颅底中线区及鞍上区内镜解剖特点,以及颅底中线区可暴露面积和鞍上区可操作空间,探讨该入路临床应用可行性和适用范围。方法2013年9月—2014年9月选用新鲜成人尸头10具,红色与蓝色明胶分别灌注动、静脉血管,75%医用乙醇浸泡保存5d,经CT薄层扫描和重建影像资料输入神经导航系统。应用直径4mm,长度18cm0。和30。硬质内镜,在神经导航辅助下模拟手术过程,采用双鼻孔扩大经鼻入路对尸头进行颅底中线区及鞍上区内镜下解剖,重点观察该入路中重要解剖结构及其位置关系,以及颅底可暴露面积及鞍上区手术可操作空间。结果内镜经鼻入路可以安全、清晰地暴露前颅底面积平均(6.43±0.7)cm2,中颅底面积平均(3.43±0.5)cm2,后颅底面积平均(8.31±1.1)cm2;由于脑池提供了自然空间,因而可以充分地暴露鞍上区,并具有较宽裕手术操作空间。结论神经内镜经鼻入路可较广泛地暴露颅底中线区,为鞍上区手术操作提供了宽广、清晰、多角度手术视野和空间。内镜经鼻入路不仅是临床治疗颅底中线区和鞍上区病变一种安全、可行微侵袭手术方法,而且是具有发展前景且不可替代手术方式。

  • 简介:摘要目的观察头颈部肿瘤放疗前CT定位中吞咽动作导致甲状软骨三维空间位置变化。方法选取2015年1月-2017年6月期间我院收治头颈部肿瘤放疗患者中CT定位时有吞咽动作30副头颈部平扫增强CT定位图像,观察平扫CT定位图像与增强CT图像中吞咽动作导致甲状软骨三维空间位置变化。结果Y轴及Z轴空间方向上甲状软骨三维空间位置变化显著,P<0.05,X轴空间方向上甲状软骨三维空间位置变化不明显,P>0.05。结论调强放疗前CT定位中患者随机性地做吞咽动作导致甲状软骨三维空间位置变化,直接影响喉部放射剂量分布,对于喉部治疗靶区导致漏照情况1,考虑吞咽导致器官位置变化时需重点考虑Y轴及Z轴方向位移。

  • 简介:摘要目的分析四维超声时间空间相关成像(STIC)和超声断层显像技术(TUI)在胎儿先天性心脏病(FCHD)筛查中应用价值。方法回顾性分析2017年5月至2021年5月在驻马店市第一人民医院进行孕期检查存在高危FCHD风险102例孕妇,均行二维超声和STIC-TUI检查,以引产或产后结果为"金标准",比较二维超声和STIC-TUI诊断结果、诊断效能、检查时间及孕妇满意度。结果本组102例高危FCHD胎儿,经引产或产后证实FCHD 31例,正常71例;采用二维超声检查出FCHD 23例,正常60例;采用STIC-TUI诊断出FCHD 29例,正常69例。TIC-TUI诊断灵敏度、特异度、准确度分别为93.55%(29/31)、97.18%(69/71)、96.08%(98/102),高于二维超声诊断74.19%(23/31)、84.51%(60/71)、81.37%(83/102);TIC-TUI漏诊率为6.45%(2/31),误诊率为2.82%(2/71),低于二维超声25.81%(8/31)、15.49%(11/71),P<0.05。STIC-TUI样本耗时、每幅图像所用时间均短于二维超声,孕妇满意度高于二维超声(P<0.05)。结论STIC-TUI应用于FCHD筛查中,可提高诊断效果,避免漏诊,能降低缺陷儿出生率,确保新生人口质量。
