Treatment of malperfusion during surgery for type A aortic dissection.
During surgery for acute type A aortic dissection, malperfusion may occur during cardiopulmonary bypass. Retrograde perfusion trough femoral cannulation is considered a predisposing factor. ⋯ A technique of epicardial ultrasound-guided direct cannulation of the dissected aorta's true lumen by a Seldinger technique may help in those cases. We describe the technique with particular interest to the epicardial ultrasound control and the type of arterial cannula to be inserted by the Seldinger technique.
