Observed clinical advantages aortic arch replacement using Hypothermic Circulatory Arrest (HCA) with Selective Cerebral Perfusion (SCP) using a 3 branch graft: Clinical study showed superior results compared to HCA alone for preventing embolic risk during operations on the aortic arch1 Reduced the amount of time and the associated complications of cardiopulmonary bypass and/or selective cerebral perfusion1 Provided better clinical outcomes in clinical studies1 and is an alternative to the Island Technique Intended to provide superior operative support by allowing precise construction of the Elephant Trunk anastomosis Clinical Applications: Thoracic Aortic Aneurysm Repair Thoracic Aortic Aneurysms (TAA) are located in the portion of the aorta that is in the chest. Treatment options for TAA include observation and risk management, open surgical repair, and endovascular repair.
