Urgent contrast-enhanced computed tomography (CECT) examinations were performed because acute aortic dissection was suspected. Early-phase CECT showed Stanford type B aortic dissection (<strong>A to C, yellow arrows</strong>, Online Video 1); however, delayed-phase CECT after 2-min intervals indicated a false lumen to show retrograde spread, and the disease classification changed to type A (<strong>D to F, white arrows</strong>, Online Video 2). Surgical repair was planned on the basis of the CECT findings of rapid progression of aortic dissection. Although administration of intravenous nicardipine and morphine were continued, the patient's pain was uncontrollable. He thereafter fell into a shock state, and repeated CECT half an hour after the first CECT examination showed a rupture of the aortic dissection (<strong>G to I, red arrows</strong>, Online Video 3). Aggressive blood-pressure lowering and pain control therapies, and urgent surgical treatment are necessary to successfully treat such patients because of rapid progression of aortic dissection and the high risk of aortic rupture.</span> http://Content.onlinejacc.org/article.aspx?articleID=1676152
