In medicine, a stent is a tube usually constructed of a metallic alloy or a polymer. It is inserted into the lumen (hollow space) of an anatomic vessel or duct to keep the passageway open. Stenting refers to the placement of a stent. The word "stent" is also used as a verb to describe the placement of such a device, particularly when a disease such as atherosclerosis has pathologically narrowed a structure such as an artery.
A stent is different from a shunt. A shunt is a tube that connects two previously unconnected parts of the body to allow fluid to flow between them. Stents and shunts can be made of similar materials, but perform two different tasks.
There are various types of stents used for different medical purposes. Coronary stents are commonly used in coronary angioplasty, with drug-eluting stents being the most common type. Vascular stents are used for peripheral and cerebrovascular disease, while ureteral stents ensure the patency of a ureter. Prostatic stents can be temporary or permanent and are used to treat conditions like benign prostatic hypertrophy. Colon and esophageal stents are palliative treatments for advanced colon and esophageal cancer. Pancreatic and biliary stents provide drainage from the gallbladder, pancreas, and bile ducts to the duodenum in conditions such as obstructing gallstones. There are also different types of bare-metal, drug-eluting, and bioresorbable stents available based on their properties.
The term "stent" originates from Charles Thomas Stent, an English dentist who made advances in denture-making techniques in the 19th century. The use of coronary stents began in 1986 by Jacques Puel and Ulrich Sigwart to prevent vessel closure during coronary surgery.
