Stent Treatment



Stent Treatment

Introduction

In the 1920s through the 1950s with the advent of cardiac catheterization and the development of angiographic technology, the stage was set for noninvasive treatment of coronary disease. The 60s first applied new techniques to revascularization of the femoral, renal, and carotid arteries that intern were adapted to the coronary arteries in the late 70s.

In short term the practice of treating coronary disease by using balloon catheters to mechanically disrupt plaques in the coronary arteries proved successful. This prompted and the development of new techniques to get rid of plaques and the use of mechanical adjuncts, or stents, in order to maintain lumen patency following angioplasty. Though effective at removing plaques, the atherectomy techniques that were developed still had serious side effects such as thrombosis and infraction (Kappenberger, 2003).

The procedure was largely abandoned in favor of angioplasty with stents in order to maintain arterial patency. Stenting became quite prevalent in Europe in the 80”s and was increasingly used as the first line of percutaneous (puncture of the skin) coronary intervention in the treatment of CAD. Methods to eliminate the side effects of radioactive pellets to inhibit cell growth in the endothelium surrounding the stent is systematic anticoagulation proved very effective and greatly reduced thrombus associated complications (Aroesty, 2006).

Stent

The concept of expanding lesions of the vessel by means of a frame 40 years ago suggested that Charles Dotter. Development of a method took a long time, the first operation of this technology was only in 1986 year. It was only in 1993, was proven effective method for restoring patency of stenting of coronary arteries and keeping it in a new state in the future.

Stent - a thin metal tube, which consists of wire cells, a special balloon inflated. He entered into the affected vessel and expands, pressed against the vessel wall, increasing its clearance. So getting better blood flow to the heart.

At the stage of diagnostic coronary angiography is performed, allowing to determine the nature, location and degree of narrowing of the coronary vessels. As a special catheter is introduced through the femoral artery contrast agent with blood, it fills the coronary arteries, allowing them to visualize. X-rays are taken at multiple angles, the result is displayed on the monitor and archived digitally.

In a specially equipped operating under the control of the X-ray producing operation, continuously recording the cardiogram of a patient. This operation does not require the implementation of the cuts, she performed under local anesthesia. The patient can speak in the process and report on his health, breathe in and hold their breath at the request of a physician.

After the vessel in the thigh or arm in the mouth of the narrowed coronary artery introduces a special catheter through which a thin metal wire is held under the supervision of the monitor. Explorer is equipped with a special balloon, which size is selected according to the peculiarities of the narrowed area. On the can is mounted stent in a compressed state, which necessarily compatible with ...
