  • 法洛四联症根治术后肺动脉瓣置换术

    目的 讨论法洛四联症 (TOF)术后肺动脉瓣关闭不全的外科治疗时机和方法。 方法  5例 TOF患者行根治术后发生严重肺动脉瓣关闭不全 ,选用液氮保存的同种带瓣肺动脉行肺动脉瓣置换术 (PVR) ,并同期分别行三尖瓣成形术 (TVP)、右心室流出道 (RVOT)成形术、VSD残余漏修补术或 RVOT疏通。 结果  1例术后早期因进行性右心功能衰竭死亡 ;余 4例均恢复良好 ,无严重心律失常 ;分别随访 3个月~ 4年 ,心功能为I ~II 级。 结论 早期 PVR能明显改善右心功能 ;采用同种带瓣肺动脉手术简便 ,早期效果满意。

  • EXPERIMENTAL STUDY ON RBC RHEOLOGY AT ARTERIAL BIFURCA TION AND END TOSIDE ANASTOMOSIS OF SMALL ARTERIES

    In order to investigate the influence on the blood flow direction and pattern at the arterial bifurcation, the mesenteric arterioles of 19 SD rats were observed under the OLYMPUS BH2 surgical microscope. After the rats were anesthetized and the body temperature was kept at 37℃ to 38℃, the mesenteric membrane wasexposed and the pattern and direction of the blood flow of the arterioles whichbifurcated at angle of 45±5°, 90±5° and 135±5° were observed. Results showed that the deformation of RBCs made them easy to adapt to the intravascular geometry and pass by fluently without sticking. It was implied that the alteration in arterial flow direction did not cause turbulance at the bifurcation site, and this in return suggested that in end-to-side anastomosis of small arteries,the flow volume would not be reduced and the chance of thrombosis would not be increased.

  • 心包开窗术在冠状动脉旁路移植术中的应用

    目的分析心包开窗术在冠状动脉旁路移植术(CABG)中的应用效果。 方法回顾性分析2011年1月至2013年4月邢台市第三医院332例冠心病患者行CABG术的临床资料。按是否行心包开窗术分为两组。开窗组:166例(男119例、女47例),年龄36~72(62.7±10.3)岁,关胸前放置心包纵隔引流管同时行心包开窗术;对照组:166例(男122例、女44例),年龄38~79(62.2±11.4)岁,关胸前放置心包纵隔引流管,未行心包开窗术。拔除引流管后1~30 d出现中等量以上积液为迟发性胸腔积液或心包积液。 结果全组手术均成功,无死亡病例;开窗组术后发生2例膈肌上抬,反复呃逆,经药物治疗后好转。两组手术时间、体外循环时间,主动脉阻断时间、死亡率差异无统计学意义(P>0.05)。开窗组迟发性胸腔/心包积液发生率较对照组低(7.2% vs.23.5%,P<0.05)。开窗组住ICU时间、住院时间、住院费用低于对照组,差异有统计学意义(P<0.05)。 结论心包开窗术用于预防冠状动脉旁路移植术后胸腔积液与心包积液安全、有效。

  • Biomechanical study of different approach for lumbar interbody fusion surgeries under vibration load

    The human spine injury and various lumbar spine diseases caused by vibration have attracted extensive attention at home and abroad. To explore the biomechanical characteristics of different approaches for lumbar interbody fusion surgery combined with an interspinous internal fixator, device for intervertebral assisted motion (DIAM), finite element models of anterior lumbar interbody fusion (ALIF), transforaminal lumbar interbody fusion (TLIF) and lateral lumbar interbody fusion (LLIF) are created by simulating clinical operation based on a three-dimensional finite element model of normal human whole lumbar spine. The fusion level is at L4–L5, and the DIAM is implanted between spinous process of L4 and L5. Transient dynamic analysis is conducted on the ALIF, TLIF and LLIF models, respectively, to compute and compare their stress responses to an axial cyclic load. The results show that compared with those in ALIF and TILF models, contact forces between endplate and cage are higher in LLIF model, where the von-Mises stress in endplate and DIAM is lower. This implies that the LLIF have a better biomechanical performance under vibration. After bony fusion between vertebrae, the endplate and DIAM stresses for all the three surgical models are decreased. It is expected that this study can provide references for selection of surgical approaches in the fusion surgery and vibration protection for the postsurgical lumbar spine.
