A new microsurgical research model using Thiel-embalmed arteries and comparison of two suture techniques.

摘要: Summary Purpose To assess the utility of Thiel arterial model in microsurgical research, we compared interrupted horizontal mattress (HM) sutures to simple (SI) human vessels. Methods A set-up using an operating microscope and Thiel-embalmed arteries was used practice ten SI HM anastomoses. Vessel patency, leak stricture were evaluated angiography, vessel wall architecture light microscopy scanning electron (SEM). The technique speed also assessed. Results We have successfully all outcomes. All anastomoses patent. rate higher with than (60% vs. 35% surface area reduction). Three minor leaks occurred versus one sutures. Edges evenly everted without any intimal flaps SI. performed faster (7:58 min 12:41 min, respectively). Conclusion This is first study evaluate feasibility a artery for research purposes. microvascular suture promising that requires further in vivo validation.
