{{Short description|Piece of thread (suture) tied around an anatomical structure}}(File:Ligature.jpg|thumb|Visual demonstration){{Medref|date=February 2022}}In surgery or medical procedure, a ligature consists of a piece of thread (suture) tied around an anatomical structure, usually a blood vessel, another hollow structure (e.g. urethra) or an accessory skin tag to shut it off.

History

The principle of ligation is attributed to Hippocrates and Galen.BOOK, Lois N.

Procedure

With a blood vessel the surgeon will clamp the vessel perpendicular to the axis of the artery or vein with a hemostat, then secure it by ligating it; i.e. using a piece of suture around it before dividing the structure and releasing the hemostat. It is different from a tourniquet in that the tourniquet will not be secured by knots and it can therefore be released/tightened at will.Ligation is one of the remedies to treat skin tag, or acrochorda. It is done by tying string or dental floss around the acrochordon to cut off the blood circulation.WEB,weblink Cutaneous skin tag, Medline Plus, 20 August 2012, Home remedies include commercial ligation bands that can be placed around the base of skin tags.WEB,weblink Skin tag removal: Optional but effective, Kristina Liu, MD, MHS, March 23, 2020, Harvard Health, Complications of ligation in polydactyly treatment include infection, neuroma or cyst formation.JOURNAL, Barnes, Curtis J., De Cicco, Franco L., 2022, Supernumerary Digit,weblink Treasure Island (FL), StatPearls Publishing, 33232075,
