Circumferential Acute Type an Aortic Dissection with Intimo-Intimal Intussusception: The Efficacy of Central Aortic Cannulation

Abstract

An 80-year-old woman suffered from acute chest pain and then exhibited cardiogenic shock. Transthoracic echocardiography revealed severe aortic regurgitation due to the intussusception of the intima. Computed tomography also showed the intussusception of the intima into the left ventricular outflow tract over the aortic valve and dissection involving the aortic root, aortic arch, and descending thoracic aorta. During surgery, echocardiography-guided central aortic cannulation was performed for the prompt establishment of cardiopulmonary bypass. The complete intimal tear was circumferentially located in the middle level of the ascending aorta. The proximal flap was inverted into the left ventricle, and the distal flap had been pushed into the aortic arch. Graft replacement of the ascending aorta was performed successfully, and the patient had an uneventful postoperative course.
