A traditional absorbable SUTURE used in surgery for tying cut arteries and stitching wounds. Consisting of twisted COLLAGEN (from sheep or cattle intestines), catgut is absorbed by phagocytes (see under PHAGOCYTE) over a variable period. There are two types: plain, and chromatised or chromic. Synthetic absorbable sutures cause less reaction, have a predictable absorption period and are more e?ective.
n. a natural fibrous material prepared from the tissues of animals, usually from the walls of sheep intestines, twisted into strands of different thicknesses and formerly widely used to sew up wounds (see suture) and tie off blood vessels during surgery. The catgut gradually dissolves and is absorbed by the tissues, so that the stitches do not have to be removed later. Catgut has now been replaced by synthetic absorbable suture material, such as vicryl.
A cord or thread used to tie around arteries in order to stop the circulation through them, or to prevent escape of blood from their cut ends. Ligatures are generally made of catgut or silk, and are tied with a reef-knot.... ligature
