Abstract: Aortic dissection is an emergency condition, which starts with a rupture in intima and inner layers of media, hematoma can spread either forwards or backwards. According to Stanford classification, there are two types of aortic dissection: type A (when ascendent aorta is involved) and type B (when descendent aorta is involved). Main factors in etiology of aortic dissection are arterial hypertension and pathologically changed media during course of other diseases. Diagnosis is made on a basis of clinical picture and imaging studies, especially computer tomography and transesophageal echocardiography. It is important to treat high blood pressure medically and to perform surgical procedure in case of type A dissection and type B with threatening complications. A blood vessel graft is inserted where aorta has initial tear. Less invasive procedure is endovascular stent graft implantation.
Key words: aorta, dissection, vessel graft, stent graft, transesophageal echocardiography
