Direct cannulation of the aortic arch guided by transesophageal echocardiography is described as a technique to provide antegrade flow during repair of Stanford type A aortic dissection.
Transesophageal echocardiography can be used to guide direct antegrade cannulation of the true lumen in the distal aortic arch during type A dissection repair, potentially minimizing malperfusion risks.
We describe an alternative technique for aortic arch cannulation that can be used during the repair of Stanford type A aortic dissection. In order to minimize the risk of complications and malperfusion associated with retrograde flow during cardiopulmonary bypass, we avoided femoral artery cannulation and used antegrade flow via a direct cannulation of the aortic arch in an area free of dissection. Transesophageal echocardiography is used peri-operatively to guide the cannulation of the true lumen in the distal aortic arch.

Noiseux et al. (2003) studied Stanford type A aortic dissection. Direct cannulation of the aortic arch guided by transesophageal echocardiography vs. Femoral artery cannulation was evaluated. Direct cannulation of the aortic arch guided by transesophageal echocardiography is described as a technique to provide antegrade flow during repair of Stanford type A aortic dissection.
