[Surgical considerations in type-B aortic dissection].
Inspite of remarkable progress in both diagnostic and therapeutic development in treating aortic dissections this continues to be one of the most severe vascular catastrophies complicated by high mortality. While aortic dissections Type A are to treat surgically in our days, in majority of patients with Type B dissections hypotensive treatment is the method of choice providing better chance for survival preventing effectively aneurysm formation and rupture at the site of intimal tear. However in certain cases Type B dissection produces either isthmic aneurysm formation, or with distal progression may afflict long segmental thoracic, thoracoabdominal or abdominal deterioration of the aorta and its side branches. The spinal, visceral, renal and lower limb ischemia threatens viability of these organs and hypotensive medication may enhance risk. Prompt evaluation and selection of these cases with proper surgical reconstruction help us to reduce mortality. At our department we have performed 33 thoracoabdominal endoaortectomies with meticulous reconstruction of renal and visceral orifices. The mortality rate in this subgroup of patients was 6%, meanwhile almost 70% in those, treated medically but had the severe distal branch involvement. Based on our experiences in selected patients with Type B aortic dissections we recommend this procedure in order to achieve improvement of results.
