颅内支架概览1颅内支架分类22颅内辅助支架的作用问题:宽的瘤颈使得动脉瘤内的弹簧圈容易移位或部分脱出到载瘤动脉里,这可能造成严重的并发症。解决方案:颅内辅助支架主要用于辅助宽颈动脉瘤的弹簧圈栓塞,防止弹簧圈的移位或部分脱出。33支架的基础知识与常用术语LOREMIPSUMDOLOR45开环vs.闭环闭环设计开环设计“游离”的尖端56颅内支架不同的网眼设计SolitaireAB-闭环LeoPlus–闭环Neuroform–开环Enterprise–闭环未连接点67输送性和可回收性输送性:支架能够被输送到病变部位的能力,尤其是通过远端病变或通过迂曲的解剖结构的能力。可回收性:支架被释放后,可以被重新收回且被重新放置到更优位置的能力。这是一项非常重要的能力,分为完全回收和部分回收。7柔软性Flexibility为柔软性,支架在闭合状态下随血管的弯曲而弯曲的能力。柔软性越好,支架的通过性越佳。889顺应性Comfortability,支架在打开状态下随血管的弯曲而弯曲的能力。顺应性好,有利于支架完全贴壁和保持血管的正常生理弯曲。顺应性差可能导致血栓的形成910支架的贴壁性支架的贴壁性:支架与血管壁贴合的能力。贴壁性不好可能导致血栓和支架移位的发生10径向支撑力是支架对血管壁的支撑能力-决定支架对弹簧圈的支撑能力-衡量支架的稳定性和移位效应111112开环vs.闭环1213毛刺现象和打折现象毛刺现象:Gator-Backing,指支架被置于弯曲解剖处时,网丝向外扩张/伸出的趋势。类似鳄鱼背脊。打折现象:支架的弯曲能力,弯曲能力差支架容易在弯曲处发生打折现象,容易造成血管的闭塞1314支架短缩?支架释放/撑开前后轴向上长度的差异所有支架都有一定程度的短缩取决于支架的材质和设计对支架的精确释放有重要的意义,但.如果支架可以完全回收重新放置,<20%的短缩率是可以接受的(如SolitaireAB)如果支架不能回收和重新放置,就需要有更低的短缩率1415金属/血管比?在覆盖支架的血管部位,支架的金属表面积/血管表面积该指标目前尚不能用于反映颅内支架的性能低金属/血管比可能降低管壁的不良反应。1516潜在并发症1支架内再狭窄(In-stentrestenosis):
狭窄是血管腔的变窄或阻塞。当支架植入血管后,血管壁的内皮被损伤,机体对损伤进行一系列主动修复。虽然此种修复是必要的,但在一些情况下,这种修复可能过度过度的修复可能导致疤痕组织在支架内聚集,导致血管腔的狭窄或阻塞,这称为“支架内再狭窄”。可能导致脑缺血性损伤。1617潜在并发症2血栓(thrombosis):支架植入后,可能导致血栓形成。-急性、亚急性-迟发型可能导致脑缺血性卒中。1718潜在并发症3支架移位边支闭塞其他..18SolitaireAB产品信息LOREMIPSUMDOLOR1920*NotapprovedforsaleintheUnitedStates.
