stent (redirected from stented)

stent (stent)

1. a device or mold of a suitable material, used to hold a skin graft in place.

2. a slender rodlike or threadlike device used to provide support for tubular structures that are being anastomosed, or to induce or maintain their patency.

Palmaz stent  an intravascular stent made of rigid wire mesh; it is introduced by a guidewire and expanded into place by a balloon.

pigtail stent  one with a curl near the end like that of a pig's tail to maintain it in place.

n.

1. A device that is used to maintain a bodily orifice or cavity during skin grafting, or to immobilize a skin graft following placement.

2. A slender thread, rod, or catheter placed within the lumen of tubular structures, such as a blood vessel, to provide support during or after anastomosis.

stent

a mold for keeping a skin graft in place, made of Stent's mass or some acrylic or dental compound; by extension, a device or mold of a suitable material used to hold a skin graft in place or to provide support for tubular structures that are being anastomosed. Also used in vascular and bile duct surgery, and repair of laryngeal, tracheal, nasal trauma and stenosis.

stent

Cardiology Intracoronary stent An expansile tube positioned in a blood vessel, especially a stenosed coronary artery, to ↑ its diameter, ergo blood flow to the myocardium; stenting of obstructed CABGs results in superior outcomes, larger gain in luminal diameter, ↓ major cardiac events. See Coronary artery bypass graft, Coronary stent, Endovascular stent, Endovascular stent-graft, Harrel Y stent, Horizon temporary stent, INR stent. Cf Balloon angioplasty Medtalk A synthetic tube placed in a tubular structure and intended to maintain that structure's open state. See Biliary stent.

Patient discussion about stented.

Q. I still have chest pain after 5 angioplasties/stents. Does anybody else still have that much angina?

A. my uncle had the same problem. went through several catheterization at several different cardiologist (some are well known), but couldn't get this annoying pain off his chest. the weird part was that it didn't even reacted to effort. but eventually (i don't remember the stent amount) one of the cardiologist solved the problem. so don't give up and continue searching the cause!

Q. How long can a person lives after having stents put into their heart?

A. PTCA stenting was associated with two major limitations: acute (during the procedure) or subacute (after the procedure and within 30 days) vessel closure, and late (four to eight months postprocedure) restenosis- meaning the stent can occlude again and cause another blood supply damage to the heart. Restenosis rates have fallen from 30 to 40 percent after just opening the blockage with balloon angioplasty to 20 to 30 percent after inserting bare metal stents to less than 10 percent with drug-eluting stents (different kinds of stents). The chances of experiencing another heart attack, in the same artery or a different, still exists, obviously, as the risk factors in the patient still exist. If non of these complications occur, the stent can last at least 10-15 years.
