Dynamic behavior of suture-anastomosed arteries and implications to vascular surgery operations.

Background: Routine vascular surgery operations involve stitching of disconnected human arteries with themselves or with artificial grafts (arterial anastomosis). This study aims to extend current knowledge and provide better-substantiated understanding of the mechanics of end-to-end anastomosis through the development of an analytical model governing the dynamic behavior of the anastomotic region of two initially separated arteries.

Methods: The formulation accounts for the arterial axial-circumferential deformation coupling and suture-artery interaction.
