Aim. After surgical treatment of type A aortic dissections a long segment of these aortas often remain dissected. Our goal was to analyse feasibility and first clinical and pathophysiological results of a combined treatment by ascending aorta replacement and stenting of the arch or descending aorta with Djumbodis(R) bare stents. Twenty two cases from two centres were analyzed (Universitary Hospital of Parma and Rangueil Universitary Hospital of Toulouse). All the stents have been implanted with short times of circulatory arrest. Average follow-up was 278 days (0-2005). There were two peroperative deaths (9.1%). One year cumulate survival rate was 72.7%. Postoperative complications were mainly respiratory and renal. We have shown a reduction in number of perfused false lumen for aortic arches, more often stented, than for descending aortas (p=0.0104), and for dissected and stented segments versus dissected unstented segments (p=0.0083). Our study demonstrates feasibility of this combined procedure and its positive effect on pathophysiologic evolution. Long term results have to be evaluated, but we think promising to extend this treatment to the whole dissected aorta.
