The circumferential ligature pattern can be used to ligate isolated vessels and small pedicles. This pattern is performed by encircling the vessel or pedicle with the suture and tying a secure knot; this is often performed in the crush of a clamp. Unlike transfixing ligatures which penetrate the structure to be ligated, this pattern only encircles the structure and could slip more easily. This type of ligature is often performed in the crush of a clamp prior to performing a transfixed ligature distal to the circumferential ligature.
