Hybrid Treatment of Type B Aortic Dissection

Superiority Trial of Type b Aortic Dissection Treatment Combined With Implantation of Bare Metal Stent in Abdominal Part of Aorta Versus Conventional Type b Treatment

Authors hypothesize that thoracoabdominal aortic repair combined with bare metal stent implantation is superior over standard thoracoabdominal aortic repair.

Main hypothesis of this study is that thoracoabdominal aortic repair combined with bare metal stent implantation is better permanent neurological deficits, perioperative bleeding, malperfusion of viscera over conventional thoracoabdominal aortic repair.
