What are the different types of endovascular stent?

Endovascular stent is a small flexible eye tube, which is located in the lining of the damaged blood vessel to open the container and permanently hold it open. Endovascular stents are either bare metal or fabric. Metal stents represent the first generation of stents, are made exclusively from metal wire mesh and do not carry medicines. On the other hand, coated stents are a newer development of endovascular stents; They can be covered with a synthetic substance, or the stent itself can be woven from fabrics and metal strands. Fabric stents are also able to contain time -released medicines in their fibers. This is the procedure used to insert the stent into tapered or blocked arteries or veins for their expansion; The small balloon at the end of the catheter inflates after the container is punctured and the stent is inserted. When the procedure is performed on the main arteries of the heart or coronary blood vessels, it is called percutaneous translational coronary angioplasty (PTCA).

stents are widely used in endovascular surgery, a type of surgery to access the main blood vessels around the heart or abdominal area without having to cut bodily tissues extensively. In 2010, the fabric stent was the most commonly used type of endovascular stent for the treatment of the aneurysms of the main coronary arteries or the arteries associated with the heart. When a fabric stent is used to repair the main artery, it is called a stent.

Stent chips are used to repair aneurysms. Aneurysm is basically a storm in a part of the aorta, which is caused by a weakened aortic wall. When this happens in the abdomen, the abdominal aortic aneurysm (AAA) is called. If there should be traumatic aortic injury, such as rupture, nor metal or fabrics of endovascular stents could not be used for repair. It is because of the nature of the wall aneurysmal vessel.

The arterial wall is in layers, with the most delicate layer closest to the area where in the lumen or central coreU flows. This layer can be torn, and this is called aortic tear. Blood inside the artery, like the river, can gradually erode part of this tears until it creates a new channel. The new channel in which blood can now flow is called a false lumen and is said to have been dissected. The echocardiogram can be used to detect fake lumen with autopsy aorta and an endovascular stent can be used to repair it.
