Diagnosis of Acute Aortic Dissection

Abstract

Acute aortic dissection (AAD) is a rare, but a life-threatening condition which arises from an intimal tear in the ascending aorta, resulting in separation of the intimal and medial layers of the aortic wall and subsequent entry of blood flow between the layers. The pressurization of the false lumen of the aorta can lead to coronary, brachiocephalic or branch vessel malperfusion, as well as aortic valve insufficiency, or aortic rupture. The International Registry of Acute Aortic Dissection (IRAD) reported the percentage of patients undergoing surgical treatment for type A AAD (TAAAD) increased from 70% to 90% and the overall surgical mortality improved from 25% to 18% form advances made in surgical techniques, anesthesia, and perioperative medical management. Herein, we describe diagnosis with using several modern modalities, including CT, MRI, Echo, and so on.
