Coupled suturing: a new technique for microvascular anastomosis.
The left carotid artery of 12 Sprague-Dawley rats was sectioned and anastomoses immediately performed utilizing a new technique termed coupled suturing. Patency and constriction were assessed immediately postoperatively and at 1, 2, and 3 weeks. Specimens were also evaluated by light microscopy and scanning electron microscopy. Vessels healed well with excellent patency and edge eversion. With the development of a specialized needle, coupled suture could prove to be a reasonable alternative to current methods of anastomosis. Its main advantage is better intimal eversion, which decreases the risk of thrombosis.
