title: The application of a modified technique of SCP under DHCA during total aortic arch replacement combined with stented elephant trunk implantation.
abstract: We reviewed the perfusion experiences of 60 cases with a modified technique of selected cerebral perfusion (SCP) under deep hypothermic circulatory arrest (DHCA) during ascending aorta and total aortic arch replacement combined with transaortic stented graft implantation into the descending aorta for acute and chronic type A aortic dissection. Right auxiliary artery cannulation was routinely used for cardiopulmonary bypass (CPB) and SCP in this procedure. Generally, this technique requires two main pumps for two arterial lines before we applied the modified technique; one for CPB and the other for SCP. In order to simplify the circuit of the extracorporeal circuit (ECC) to operate easily, the arterial line was separated into two branches with a Y-connector on the operating table, one for axillary artery perfusion and the other for graft perfusion connected to the ECC set-up. This method is easy for the perfusionist to install and convenient for the surgeon. This is a safe and simple to use modified technique for SCP under DHCA during ascending aorta and total aortic arch replacement combined with transaortic stented graft implantation into the descending aorta.
