The aim of the study was to assess technical success rates of endovascular procedures in acute and chronic type B aortic dissections and changes in the right (PL) and false (FL) lumen diameters in the visceral segment region during short-term and long-term follow up study periods. ⋯ False lumen thrombosis along the extent of SG was recorded in 30 (91%) patients, SG filled the lumen completely and the false lumen disappeared. The true lumen expanded at all the measured visceral segment levels. The change was most significant during the first postimplantation month, and the true lumen expansions and the false lumen narrowing proceeded over the whole follow up study period, however, the progression was slower. The visceral segment true and false lumen changes will be monitored further.
