Aortic aneurysm
The aorta is the largest artery of the human body, starts from the heart (from the left ventricle specifically), permeates the chest and abdomen and reaches to the umbilical cord, where it is divided into the so -called iliac arteries (right and left). Its average normal diameter in the chest (thoracic aorta) is up to 28 mm, while in the abdomen (abdominal aorta) about 20 mm. When the diameter of an vessel exceeds the maximum normal diameter by 1.5 times then we talk about aneurysm. This is when the diameter of the thoracic aorta passes 4.5 cm (45 mm) and the abdominal aorta 3 cm (30 mm).
The arteries (with the exception of the pulmonary arteries) are the conductors that carry blood rich in oxygen from the heart to the rest of the body to nourish it. The interior of the arterial lumen is smooth to allow for trouble -free blood flow. Over time, however, their inner wall can become thick and abnormal by deposits of materials such as cholesterol, calcium, damaged cells and fibrous tissue. This is mainly the case where the arteries branch. These deposits are the so -called atherosclerotic plaque . This disease is known to all atherosclerosis .

Carotid
disease
The common carotids penetrate the throat and in its middle or just before the lower jaw they are divided into the outside and inward carotid . Outdoor pathologies do not need treatment because they are not actively involved in the supply of the brain with blood. But the narrowing of the inner and the common carotid are the ones that focus our interest as they play the key role in brain hemorrhage .
Varicose veins are a disease of the veins of the lower extremities. Our veins, in normal conditions, carry blood poorer to oxygen back to the heart to lead to the lungs and purify. The veins of the lower extremities, due to our upright walking, are burdened by returning a large volume of blood to the heart. In many people, there is a weakening of the venous wall in the lower extremities that results in the gradual malfunction of the venous valves .

Venous
thrombosis
The venous thrombosis is called the pathological formation of blood gel (thrombus) in the lumen of a vein resulting in obstruction. Coagration factors play a key role in the formation of thrombus. In cases of abnormalities responsible genes for coagulation factors there is an increase in thrombosis in an organism.
