[Surgical treatment for ascending aortic aneurysm using a transthoracic left ventricular venting].
Three patients with ascending aortic aneurysms underwent graft replacement using deep hypothermic circulatory arrest with continuous retrograde cerebral perfusion. In all three cases, preoperative radiographic examination revealed that the aneurysm was large, thin, and adherent to the back of the sternum. For this reason, left ventricular venting was performed through a left thoracotomy before median sternotomy, to decrease both the risk of rupture of the aneurysm and the difficulty of cannulation. This new method, called transthoracic left ventricular venting, was very useful for performing a median sternotomy under hypotensive and hypothermic conditions adequate to reduce the risk of rupture and to manage any rupture immediately through deep hypothermic circulatory arrest.
