The Greek word aneuryneim or aneuryneim which means to dilate. The aneurysm is a bulge filled with blood that is medically described as a pathological dilation of the blood vessels, located in the arteries or veins as the walls are altered due to a sudden or progressive degeneration of the same.
True aneurysms are classified as those that form in the walls of the blood vessels and false aneurysms that fill with blood the spaces that communicate the arteries in a normal opening, these being the most frequent that are located at the base of the brain in the polygon of Willis and in the Aorta in its different sections of it and that is the main artery that leaves the heart and is called Aortic aneurysm and can be thoracic or abdominal.
They are classified into several types of aneurysm: the fusiform aneurysm, is when the blood vessel dilates, deforming in a diffuse way, the saccular aneurysm, is when a good part of the wall of the blood vessel is normal, but the other that composes it is not and It is dilated preventing circulation, the pseudoaneurysm aneurysm, is when the layer of the aortas separate making an empty space and in its defect it is filled with blood, causing the artery to dilate and deform.
This congenital disease by producing these widening and deforming the vessels and arteries, the risk of a rupture of the same occurs, if it is not broken it produces headaches and paralysis of the nerves, but in which case it is contrary to break, the headaches intensify and appear abruptly at the risk of a cerebrovascular accident, with frequent fainting that upon waking up the headaches reappear, in the same way as they occur in the aorta artery and the brain, they also appear in the back of the leg, behind the knee to be specific, the intestines and the spleen.
One of the frequent causes of its appearance is due to suffering from syphilis and arteriosclerosis that appear in the abdominal and thoracic aorta, forming a type of pulsatile and expandable tumor being of a mortal severity when producing effusions or hemorrhages with the sudden death of the patient.
