Echo-guided seldinger technique facilitates ascending aorta cannulation in type A aortic dissection

Abstract

Abstract Background The ascending aorta is the most simple and rapid arterial access for the establishment of antegrade systemic perfusion. In acute type A aortic dissection, prompt establishment of antegrade central perfusion, especially in unstable hemodynamic emergency operations, help to diminish organ malperfusion and to prevent retrograde embolism. The effectiveness as well as the safety of antegrade perfusion under ultrasonographic guidance through the dissected ascending aorta was evaluated for the repair of type A aortic dissection utilizing a new echo stabilizer. Results Ascending aortic cannulation was successfully performed in 64 consecutive patients, using the Seldinger technique, with the hands-free continuous-echo monitoring, utilizing a new stabilizer. Epiaortic 2-Dimensional and color Doppler imaging provided real-time monitoring for the placement and proper perfusion of ascending aorta cannulation. Conlusions Ascending aorta can routinely provide a rapid and reliable route of antegrade central systemic perfusion in type A acute aortic dissection. The echo-guided stabilizer-assisted cannulation method can safely provide a rapid and reliable route for antegrade central perfusion during in type A dissections repair.
