Fig. 9From: Modified transesophageal echocardiography of the dissected thoracic aorta; a novel diagnostic approachModified TEE long- and short axis (X-plane) images of the innominate artery. Panel (a) Image before surgery, showing propagation of an intimal tear into the innominate artery with almost complete obstruction of the vessel with limited perfusion of the true lumen. Panel (b) Image after surgery showing a normal flow pattern during extracorporeal circulation; artefact in the long-axis view, which does not indicate a persistent dissection. 1 = Trachea with inflated endotracheal balloon; 2 = Innominate arteryBack to article page
