A drug-eluting stent (DES) is a small mesh tube that is placed in the arteries to keep them open in the treatment of vascular disease.The stent slowly releases a drug to block cell proliferation (a biological process of cell growth and division), thus preventing the arterial narrowing that can occur after stent implantation.
For some high-risk cardiovascular patients with stents, the often-recommended practice of prolonged taking of aspirin might be ineffective, and in some cases, even harmful, a new study found.
A coronary stent is a tube-shaped device placed in the coronary arteries that supply blood to the heart, to keep the arteries open in patients suffering from coronary heart disease. The vast majority of stents used in modern interventional cardiology are drug-eluting stents (DES).
At the present time, there is one temporary prostatic stent that has received U.S. Food and Drug Administration (FDA) approval. [4] The Spanner [5] temporary prostatic stent maintains urine flow and allows natural voluntary urination. The prostatic stent is a completely internal device and can be inserted and removed as easily as a Foley ...
The first two drug-eluting stents to be utilized were the paclitaxel-eluting stent and the sirolimus-eluting stent, both of which have received approval from the U.S. Food and Drug Administration. Most current FDA-approved drug-eluting stents use sirolimus (also known as rapamycin), everolimus and zotarolimus.
Intracranial bleeding (ICB) and subsequent stroke is a serious side effect of thrombolytic use. The risk factors for developing intracranial bleeding include a previous episode of intracranial bleed, advanced age of the individual, and the thrombolytic regimen that is being used. In general, the risk of ICB due to thrombolytics is between 0.5 ...
Treatment of internal bleeding is beyond the scope of simple first aid, and a person giving first aid should consider it potentially life-threatening. The definitive treatment for internal bleeding is always surgical treatment, and medical advice must be sought urgently for any victim of internal bleeding.
Bleeding may originate from the aorta, the anastomosis, an insufficiently sealed branch of the conduit, or from the sternum. Other causes include platelet abnormalities or their failure to clot —perhaps due to the bypass or to the rebound heparin effect, which occurs when the anti-coagulant heparin is administered at the beginning of surgery ...
