Stenting
Stenting
Stenting (pronunciation: /ˈstɛntɪŋ/) is a medical procedure that involves the placement of a small mesh tube, known as a stent, into a narrow or blocked artery. The stent helps to keep the artery open, improving blood flow and helping to prevent heart attacks.
Etymology
The term "stenting" is derived from the English word "stent", which itself is named after Charles Thomas Stent, a British dentist who invented a compound used in early dental procedures. The term was later adopted in the medical field to describe the process of inserting a tube into a body passage to keep it open.
Procedure
The stenting procedure typically involves the use of a catheter, a thin tube that is threaded through the patient's blood vessels to the site of the blockage. A balloon angioplasty is often performed first to widen the artery, after which the stent is placed at the site of the blockage to keep the artery open.
Types of Stents
There are several types of stents used in medical procedures, including bare-metal stents, drug-eluting stents, and bioresorbable stents. The type of stent used depends on the specific needs of the patient and the nature of the blockage.
Risks and Complications
While stenting is generally considered a safe procedure, there are potential risks and complications. These can include restenosis, the re-narrowing of the artery, and thrombosis, the formation of a blood clot inside the stent.
