What is a medical stent?

Elutation of a drug or drug is a small tube or pipe coated with different types of drugs that are essentially used in cardiac procedures to maintain open blood vessels. These devices were first tested at the beginning of 2000 and are now available on the market. The purpose of coating the stent by drugs is that they will be released into the artery, which prevents the formation of scar tissue, which in turn prevents blocking the stent. Since its introduction, the medicated stent has to know controversy, because it seems that it is more likely to promote blood clotting and increase the risk of stroke. Due to these risks, special medical instructions are followed when using these stents.

One of the potential risks of bare metal stent is that it can irritate the blood vessel and cause scar tissue formation. This leads to what is called stentine restenosis or narrowing, and it can lead to the need to replace the stent or take other medical measures to repair and maintain the blood vessel open. The medik stent was afterThe first celebrated as a solution to this problem, because it tended to significantly reduce the risk of restenosis by inhibiting the tissue of scar formation. To achieve this goal that eliminate or release from the stent, they include orphanus and paclitaxel. Other drugs are studied as potentially beneficial for stent coats, with special interest in coatings that are biodegradable.

Numerous research studies have shown that medical types of stent are more effective than untreated species in the prevention of restenosis stent. In the middle of the first decade of 2000 years, there was also evidence that drug stents cause people at an increased risk of blood clots. Although during the use of a stent, patients with treated stents seemed to be better, statistically snap the risk of shaping thrombi was higher in the users of the medical stent group. This report caused this report to panic between the stent -producing industry.Other studies have proposed a way to approach this problem and maintain medicinal stents as a viable choice for patients.

Due to the known increased risk of blood clots, if used by a medicated stent is now the standard of providing therapy to help prevent blood clotting for half a year to 12 months or more. Usually, the drug Plavix® (Clopidogrel) is used and can be used in conjunction with aspirin. Therapy usually starts immediately after the stent is placed. Its main disadvantage may be the cost, especially because people who receive stents are likely to be more than 65 years old and may have limited prescription drug coverage.
