What is endovascular aneurysm?

Endovascular aneurysm (EVAR) is also known as the endovascular stent Štěp. According to both names, this procedure concerns the closed chest method repair of certain aneurysms, most often aortic, but sometimes thoracic. Aneurysms are great weaknesses in the blood vessel, which can eventually cause to collapse or burst, which is an instantly threatening life. While the standard method for their repair is the opening of the chest or other part of the body and removing or strengthening the affected artery, the interest in the less invasive procedure has led to the development of EVAR. Instead of cutting into the chest, a surgeon or a cather specialist, often a vascular surgeon, a slight sedation, and enters the aneurysm source by artery in a weakness. The catheter that contains the stent is stretched by the artery until it reaches the SOUCce aneurysm. The stent is then released to stabilize aneurysm and prevent the vessel from getting worse.

Another method for performing chest or aortic aneurysm is an open procedure. The chest is cut and aneurysm is located and repaired. This operation usually includes a much longer period of recovery in the hospital and verify them more painful while a person is healing. In short -term estimates, such as the first month after surgery, it has a slightly higher mortality than endovascular repair of aneurysm, but in the long run both procedures are considered to be equal to survival.

There are great questions that have led to continuing studies on the benefits of repairing endovascular aneurysms versus open procedures. Researchers have so far found that Evar has the advantages of early stages due to their short recovery time and Slightly has reduced early mortality, but that it requires greater monitoring than open repairs and tends to be more expensive. These factors are good to consider in a vascular surgeon, provided they are time to consider them, which is not always.

It should be noted that not all people areGood candidates to repair endovascular aneurysms and others are more at risk if they have open operations. The high risk of open surgery suggests that Evar is a better choice. Another thing that can affect this decision involves the size of aneurysm, because the smaller size may not be large enough for the stent. It may also depend on the aneurysm. Whenever Evar is considered, one of the principles of the question is whether the stent will adequately strengthen the artery; If this is not the case, an open operation is usually preferred.
