Posterior-Wall-First Continuous Suturing Combined with Conventional Interrupted Suturing for Microvascular Anastomosis

ABSTRACT

Vascular anastomosis with conventional interrupted suturing is often difficult to perform when the vascular clamp is not reversed, because of a narrow operative field or a short vascular pedicle. A posterior-wall-first continuous suture technique combined with the standard interrupted suture technique is one method of solving this problem. The authors conducted a comparative study of posterior-wall-first continuous suturing combined with standard interrupted suturing and conventional interrupted suturing in rat vessels. There was no statistically significant difference in patency rates or suturing times. Electron microscopy demonstrated no significant difference in recoverability of the intima. The posterior-wall-first continuous suture technique combined with the standard interrupted suture technique is a useful alternative to the conventional interrupted suture technique.
