Objective To elucidate the new development, structural features and appl ication of the lumbar interspinous process non-fusion techniques. Methods With the review of the development course and important research works in the field of the lumbar inter-spinous process non-fusion techniques, the regularity summary, science induction, and prospect were carried out. Results The lumbar inter-spinous process non-fusion technique was a part of non-fusion insertof spinal division posterior surface. According to the design, it could be divided into two major categories: dynamic and static systems. The dynamic system included Coflex and device for intervertebral assisted motion; the static system included X-STOP, ExtenSure and Wall is. The lumbar inter-spinous process non-fusion technique was a new technique of spinal division, it could reserve the integrated function of intervertebral disc and zygapophysial joint, maintain or recover the segmental movement to a normal level, and have no adverse effect on the neighboring segments. A lot of basic and cl inical researches indicated that lumbar inter-spinous process insert had extensive appl ication to curatio retrogression lumbar spinal stenosis, discogenic low back pain, articular process syndrome, lumbar intervertebral disc protrusion and lumbar instabil ity and so on. Conclusion With the matures of lumbar inter-spinous process non-fusion techniques and the increased study of various types of internal fixation devices, it will greatly facil itate the development of treatment of lumbar degenerative disease. But long-term follow-up is needed to investigating the long-term efficacy and perfect operation indication.
目的 探討64排螺旋CT血管探針技術在評價腎動脈狹窄中的價值。 方法 回顧分析2010年4月－2012年1月51例行64排螺旋CT腎動脈血管成像且腎動脈狹窄患者的臨床資料，對雙側腎動脈行血管探針重組，分析血管狹窄的原因，以及累及范圍、狹窄程度。 結果 51例患者雙側腎動脈共105支（3支副腎動脈），其中管腔正常腎動脈27支，管腔有狹窄腎動脈78支。管腔狹窄者中，腎動脈斑塊血管共65支，累及范圍主要為局限性，以混合性及輕度狹窄為主；腎動脈夾層4支，累及范圍主要為節段性，假腔內無對比劑，真腔輕中度狹窄為主；腎動脈腫瘤包繞共有9支，累及范圍主要為節段性，腔輕度狹窄為主。 結論 64排螺旋CT血管成像清晰顯示腎動脈，血管探針技術分析血管快速、可靠，能準確評價腎動脈狹窄，對指導臨床治療具有重要的意義。
