[Synthetic endovascular prostheses in the treatment of the aortic dissection]

Endovascular technique using endovascular prostheses called stent-grafts offers less invasive new method of the aortic dissection. Assessment of endovascular aortic dissection type B treatment effectiveness, complications and mortality frequency associated with this technique. Among 33 patients (24 men -- 73% and 9 women -- 27%, aged 19-76 years (average [+/- SD]. Underwent endovascular stent-grafts implantation procedures using 3 types of grafts: Zenith (2 prostheses -- 13,3%), Talent (11 prostheses -- 73,3%) and Valiant (2 prostheses --13,3%). The diameter of proximal end of stent-graft ranged from 34 to 42 mm (mean 37,6 +/- 3,44 mm), length -- from 130 to 230 mm (mean 183,6 +/- 37,42 mm). Endovascular technique is promising strategy of aortic dissection type B treatment. Stent-graft application faces up to general aspiration to minimize extension and traumatization of surgical procedures, to reduce peri- and postoperative complications, decrease hospitalization and convalescence period. Endovascular technique is the only available method that interferes in the elementary mechanism of the aortic dissection pathogenesis. Through the initiation of natural repair process (thrombosis of the false lumen), as a result of coverage of the primary entry tear, ensures remodeling and stabilization of the aortic wall.
