We thank Dr Maurizio Salati for his comments on cannulation of the distal axillary artery in descending thoracic aortic surgery using the open proximal aortic anastomosis technique under deep hypothermic circulatory arrest. Actually, since 2001, we also have used a similar technique for more than 100 patients having various types of descending thoracic and thoracoabdominal aortic lesions requiring an open proximal aortic anastomosis around the aortic arch. In our technique, a 10F to 16F thin-walled cannula is directly cannulated into the distal part of the left axillary artery with additional cannulation of the femoral artery. Venous drainage is performed through the right atrium via the femoral vein and main pulmonary artery. Cardiopulmonary bypass is initiated with core cooling to profound hypothermia at approximately 18°C. The flow rate of left axillary artery perfusion is maintained in the range of 1000 to 1500 mL/min to prevent a potential risk of retrograde . . . [Full Text of this Article]
