Endovascular stent surgery is a minimally invasive clinical process conducted to handle an aneurysm in the aorta, the blood vessels vessel that transports oxygen-rich blood from the heart to various parts of the body. An aortic aneurysm is a situation characterized by abnormal ballooning or bulging of the aorta section due to instability in the wall of the blood vessel. An aneurysm may develop anyplace along the aorta. Aneurysms that occur in the sector of the aorta that embodies the chest are called thoracic aortic aneurysms. Aneurysms that take place in the aorta segment that moves through the abdomen are termed abdominal aneurysms. Endovascular stenting is generally recommended if conservative treatment measures have failed to relieve the symptoms of an aortic aneurysm or if there is a threat of rupture due to the huge size of the aneurysm. The judgment on endovascular stenting is depended on the total of the aneurysm and the rate at which it is enlarged.
