摘要:
 【摘要】 目的 评价新型左盘无铆型卵圆孔未闭(PFO)封堵器经导管植入的可行性、安全性和有效性,为临床研究提供实验依据。方法 取20只健康成年犬,经皮房间隔卵圆窝穿刺、球囊扩张术建立犬PFO模型。将20只犬分为实验组(植入左盘无铆型PFO封堵器)和对照组(植入双铆型PFO封堵器),每组10只。术后1、2、3和6个月分别通过对心脏大体标本、光镜、电镜检查,评价新型封堵器植入后内皮化过程,观察有无残余分流、血栓形成等并发症。结果 20只犬均成功进行了房间隔卵圆窝穿刺和球囊扩张术,右房造影可见对比剂由右房进入左房,成功建立了犬PFO模型。 实验组左盘无铆型PFO封堵器植入成功率为10/10,对照组成功率为9/10。19只犬术后1、2、3和6个月分别取出心脏大体标本进行观察,结果显示两组PFO封堵器的位置均无移位,无合金丝断裂,封堵器表面未见血栓形成和赘生物附着。术后1个月实验组封堵器双侧盘面可见薄层透亮组织覆盖,病理和电镜检查证实为纤维组织和内皮细胞,盘面无血栓和赘生物。至术后6个月,封堵器表面组织逐渐增厚,封堵器边缘与周围心脏组织融合。术后1个月对照组封堵器左侧盘面除中央铆钉外可见纤维组织和内皮细胞覆盖,术后6个月1只犬的左盘铆钉上仍无组织覆盖。结论 新型左盘无铆型PFO封堵器设计科学,与双铆型PFO封堵器相比较,完全内皮化的时间缩短,可有效的封堵PFO,具有良好的临床应用前景。
