背景:没有邻近血管肌肉结构的乳内动脉(IMA)的选择性骨架化减少了对胸壁的创伤,导致移植物伸长,使理想的移植物定位成为可能,并且无需通过直接视觉控制血管来植入解剖或发育不全的移植物。我们在一项前瞻性随机试验中比较了两种 IMA 骨架化技术。方法:随机收集 51 个 IMA,并根据骨架化技术分为两组。在第一组 (n= 31) 中,使用谐波超声手术刀以骨架化方式收获 IMA,在第二组 (n= 20) 中使用剪刀和止血夹。我们比较了两组之间的动脉壁组织学、采集时间、痉挛频率以及止血夹的使用情况。结果:两组的动脉壁形态没有显着差异。使用超声激活手术刀减少了 IMA 的采集时间 (p< 0.001)、痉挛频率 (p= 0.01) 和止血夹的使用 (p< 0.001)。 结论:超声采集骨架 IMA 是一种非创伤性准备技术,可降低手术夹的成本,并且可以安全、快速地进行。
Background: Selective skeletonization of the internal mammary artery (IMA) without adjacent vasculo-muscular structures reduces trauma to the chest wall, results in elongated grafts, makes ideal graft positioning possible, and eliminates the need to implant a dissected or hypoplastic graft with direct visual control of the vessel. We compared two techniques of skeletonizing the IMA in a prospective randomized trial.Methods: 51 IMAs were randomly harvested and divided into two groups according to the technique of skeletonization. In group I (n= 31), IMAs were harvested in a skeletonized fashion with the Harmonic Ultrasonic scalpel, and in group II (n= 20) using scissors and hemostatic clips. We compared arterial wall histology, harvesting time, spasm frequency, and the use of hemostatic clips between the two groups.Results: There were no significant morphological differences in the arterial wall in the two groups. Use of an ultrasonically-activated scalpel reduced the IMA's harvesting time (p< 0.001), the frequency of spasm (p= 0.01), and the use of hemostatic clips (p< 0.001).Conclusions: Ultrasonic harvesting of a skeletonized IMA is a non-traumatic preparatory technique that reduces the costs of surgical clips and that can be performed safely and quickly.
