Surgical treatment of Stanford type A aortic dissection remains a difficult challenge. Among of the first problems that the surgeon faces are the site and the type of arterial cannulation, which are of paramount importance in having a good arterial flow, ensuring a good body perfusion without damaging organs, not extending the dissection, speeding up surgical correction, and ensuring antegrade post-correction flow.
We developed a modified right-angled cannula that allows cannulation of the innominate artery (IA) and uniform perfusion throughout the procedure.
Methods
A preoperative computed axial tomography scan clearly identifies the extent of the dissection and the vessels involved. The right radial artery is cannulated for arterial pressure recording. A right groin incision is performed, and the femoral vessels are exposed but not cannulated. Median sternotomy is performed, and the IA is isolated. After systemic heparinization, the IA is cannulated with our modified cannula. We use a 20F to 22F cannula with a
