Endoprosthesis of the abdominal aorta


The aorta is the largest human artery through which blood is sent from the heart to the organs and which is divided into several sections:

  1. Ascending aorta;
  2. Arc;
  3. The descending part of the aorta.

A serious problem is a condition in which excessive expansion – protrusion occurs in a certain area of the aorta.

If the pathologically altered area is below the diaphragm, then they speak of an aneurysm of the abdominal part of the descending aorta.

In most patients, an aortic aneurysm may develop for several years before showing any signs of disease (symptoms). With an abdominal aortic aneurysm, the following symptoms are observed:

  1. Dull abdominal pain;
  2. Feeling of pulsation in the abdomen;
  3. Back pain.

An aneurysm of the abdominal aorta is a dangerous condition that can be life threatening, as there is a possibility of rupture of the aorta. The choice of aneurysm treatment depends on the presence of symptoms and the size of the aneurysm. Emergency surgery is required when an aneurysm ruptures. Such operations are accompanied by a much greater risk for the patient than during elective operations, when it is possible to fully examine the patient and carefully prepare for the surgical intervention.

Along with traditional operations for abdominal aortic aneurysms, a new method of treatment can be applied – EndoVascular Repair of aorta (EVAR). The method consists in the fact that through a small puncture of the artery in the thigh, through a catheter, a special vascular prosthesis is inserted into the aorta, which is fixed from the inside to the normal parts of the aorta above and below the location of the aneurysm. Such an operation is less traumatic, does not require opening the chest cavity and is relatively easily tolerated by patients.
