【摘要】 目的 评估新型国产镍钛合金封堵器封堵犬左心耳的临床可行性和有效性。方法 选择清洁级健康成年杂种犬14只,采用自主研制的新型国产镍钛合金左心耳封堵器,经股静脉途径穿刺房间隔封堵左心耳。分别于术后即刻、1个月、3个月通过解剖、经食管超声心动图(TEE)检查等方法观察封堵效果。结果 14只实验犬中11只成功植入封堵器(其中2例因术中封堵器大小不合适,回收后再次植入成功),2例房间隔穿刺时穿刺针误入心包引起心包积液而终止手术,1例术后随访发现封堵器脱入左心室,无其它手术并发症。术后各时间点分别处死实验犬,术后1个月大体观察见封堵器表面覆盖稀疏细胞,其上有内皮细胞,未见血栓及赘生物。术后3个月TEE检查见封堵器形态、位置良好,左心耳被完全封堵,左心房内无血栓形成;大体解剖见封堵器表面完全被内皮细胞覆盖,肝、肾、脾脏无血栓栓塞或梗死灶。结论 新型国产镍钛合金封堵器经导管封堵左心耳完全可行,中期效果理想。
