Figure 2: Computed tomography scan (CT) images showing the results of two different surgical techniques on arterial take-off angle. Upper panel (A-B): preoperative and postoperative CT three-dimensional reconstruction of AAOLCA (red dotted line) managed by Neo-ostioplasty - Vouhé technique ( yellow arrow). Lower panel (B-C): CT axial view of preoperative (α) and postoperative (β) AAORCA managed by unroofing. It is possible to appreciate the more rectilinear origin of the arteries from the aorta.
