Rapid and sutureless anastomosis of artificial vascular replacement of abdominal aorta in dog models using magnetic compression anastomosis technique

  • 摘要:   目的  探讨利用磁压榨吻合(MCA)技术实现犬腹主动脉人工血管置换快速无缝线吻合的可行性。  方法  选择成年健康杂交犬12只,按腹主动脉与人工血管吻合方式分为MCA组和手工缝合(HS)组,每组6只。比较两组术中腹主动脉阻断时间、术中吻合口情况与术后吻合口影像学检查情况。  结果  MCA组腹主动脉阻断时间短于HS组[(5.2±2.3)min比(24.4±4.3)min],差异有统计学意义(P < 0.001)。MCA组术中吻合口无渗漏血及狭窄情况发生;HS组术中6只犬均发生吻合口渗漏血,其中1只犬因失血过多死亡,2只犬因反复修补而出现吻合口轻度狭窄。MCA组术后彩色多普勒超声与血管造影检查显示吻合口血流通畅,无狭窄及血栓形成,HS组术后4周时血管造影检查共发现4只犬吻合口狭窄。  结论  利用MCA技术可实现犬腹主动脉人工血管置换快速无缝线吻合,减少吻合口并发症的发生,有利于术后恢复。
