Endovascular treatment of type „A“ and type „B“ dissection of the aorta

Abstract

During the period from March 2014 to May 2018, endovascular treatment of aortic dissection type A and type B was carried out in a total of 70 patients. Patients were divided into two groups, aortic dissection type A (14 patients) and type B (56 patients), a group-by-group descriptive analysis was conducted, and then a comparison was done between the two patient groups.  The aim of the study was to establish the effective use of endovascular treatment in type A and type B aorta dissection. As a result of the survey, data on the demographic characteristics and risk profile of these patients are accumulated for the first time in Bulgaria. Endovascular treatment options for the treatment of aortic dissection type A and type B, as well as malperfusion syndrome, are examined, demonstrating their effectiveness and safety. As a result of the study, it is proven that endovascular treatment in aortic dissection type A and type B leads to a significant increase in the size of the true lumen and reduction of the false lumen, which leads to an improvement in perfusion and reduces the risk of developing an aneurysm and rupture.  The presence of endoleak and persistent communication between the false and the real lumen are the most common causes of re-intervention, such as endovascular options are most often the first line for their dealing and are proven to be effective and safe.  Treatment of dissection of the aorta type A and B is not a one-time act, but requires periodic diagnostic control and, if necessary, surfery and/or endovascular corrections of the complications that have arisen.
