Multidisciplinary preoperative simulations to optimize surgical outcomes in a challenging case of the complete double aortic arch in the adult.

<bold>Background: </bold>Challenging surgical cases are becoming more and more frequent, making the optimization of decision making process and an accurate preoperative planning mandatory in order to improve postoperative outcomes.<bold>Aims: </bold>Here we present an original multidisciplinary approach aimed at optimizing decision making in a peculiar case of double aortic arch (DAA) presenting in an adult patient.<bold>Materials and Methods: </bold>Following the diagnosis of DAA, based on conventional exams, a three steps engineering simulation was adopted including: a) three-dimensional (3D) rapid prototype simulation; b) computational fluid-dynamic analysis; c) 3D virtual simulation of surgical exposure.<bold>Results: </bold>Based on careful evaluation of such simulations we were able to identify optimal anatomical and functional surgical options, along with the optimal surgical approach.<bold>Discussion: </bold>In peculiar clinical case, a significant step forward to optimize preoperative surgical planning could be obtained applying current available engineering techniques.<bold>Conclusion: </bold>We do believe that a multidisciplinary approach could become mandatory, in challenging cases, to optimize preoperative planning and outcomes.
