stent thrombosis


Also found in: Dictionary, Thesaurus, Encyclopedia.

stent thrombosis

A blood clot that forms inside a device inserted into a blood vessel to keep that vessel open.

Patient Care

Stents are deployed in completely obstructed or partially blocked arteries to keep blood flowing through them to the organs they supply. When this blood flow stops due to clotting within the stent, the organ may become ischemic and die. To reduce the risk of clotting within a stent, patients use antiplatelet drugs, like aspirin, dipyridamole, or clopidogrel, and medications to lower serum lipid levels. Tobacco cessation, and healthy lifestyle changes (eating lighter, exercising regularly) may also be helpful.
