arterial stent
Tubular mesh device deployed within an artery to maintain vessel patency and structural support.
Full Definition
An arterial stent is a small, expandable tubular mesh device made of metal or polymer that is deployed within an artery to maintain vessel patency, provide structural support, and prevent restenosis following angioplasty. Stents can be balloon-expandable or self-expanding, and may be bare metal or drug-eluting to reduce tissue proliferation. The deployment of arterial stents requires precise sizing, positioning, and expansion to ensure optimal results. Stent placement is commonly performed for treatment of atherosclerotic stenoses, dissections, or to maintain patency following atherectomy. Post-deployment imaging is essential to confirm proper expansion, position, and absence of complications.
Usage
Usage note: Specify stent type, size, and location when documenting placement in medical records.
