Summary

The topic of this paper is the endovascular treatment of thoracic aortic dissection Stanford type B and treatment of ischaemic complications associated with aortic dissection. This method leads to thrombosis of the false lumen in the descending thoracic aorta and its stabilisation, remodelling and prevention of subsequent rupture. We have demonstrated the positive impact of a successful endovascular treatment of aortic remodelling and consolidation within 3 years after the implantation of the stent graft. We have shown a gradual decline of the overall diameter of the aorta in the descending thoracic aorta, especially at the expense of reducing the volume of the false channel, with a gradual increase in the size of the true channel. This positive trend was present in patients treated in acute or subacute stages of dissection as well as in the chronic stage of aortic dilatation. Very interesting and important to us is the subsequent development of the overall width of the aorta, the false and true channel in the abdominal aorta, which is not treated with a stent graft, and in most cases, a perfusion of the false channel persists due to a re-entry at the site of a distance between visceral and renal arteries. Despite the false channel perfusion, however, there is no dilatation of the abdominal aorta, and the size of the true and false channel does not change in time.
