摘要:
目的改良和评价建立犬颈动脉侧壁动脉瘤模型的方法。方法以显微外科缝合技术在15条犬的双侧颈动脉建立多枚动脉瘤模型。随机分为3组,分别采用术中肝素化(A组)、术后肝素化(B组);不肝素化(C组)3种处理,于模型建立后2周及1个月行血管造影确认结果。2周、1个月时随机取材行动脉瘤病理学检查,对不同抗凝处理条件动物2周时的模型建立结果进行统计学比较。结果成功建立了37枚侧壁宽颈动脉瘤,血管造影示血流从动脉瘤远侧壁进入瘤内,沿着瘤壁从近侧壁流出,瘤腔中心有涡流。C组有6枚、A组有1枚动脉瘤自闭。3组共有5枚动脉瘤内有部分血栓形成,A组与B组间血栓形成率无差异(Nemenyi法:P>0.5)。组织病理学提示2周时的动脉瘤内有较明显的内膜增生和炎症反应,瘤颈处缝线无完整内膜覆盖。1个月时动脉瘤瘤壁炎症反应消退,瘤颈处缝线有完整内膜覆盖,流入道受血流冲击处可见瘤壁内膜增生。结论建模时术后肝素化与术中肝素化可达到同样的抗凝效果,外科缝合建立多枚动脉瘤可控性好,并可实现自身对照和空白对照,在对动脉瘤治疗技术的研究中有一定的优势。
