Abstract
Background: Aortic dissection (AD) is a life-threatening disease with high mortality rate. Severe pain in chest, back or abdomen is the most common symptom. Painless, but with a variety of other symptoms, also happened in some AD patients. Asymptomatic AD is exceptionally rare and often under-recognized. Case presentation: A 51-year-old man presented to cardiovascular department accompanied with an exaggerated low DBP and widened PP when measuring routine BP. Blood pressure was 124/36 mmHg (PP 88mmHg) in his right arm and 108/32 mmHg (PP 76mmHg) in his left arm. Transthoracic echocardiography was scheduled and showed that dissection intimal flaps are visualized in the aortic root, aortic arch and descending aorta. Subsequent CT angiography (CTA) was performed and demonstrated that a long-segmental AD occurred from aortic root to left common iliac artery. The patient underwent replacement of the aortic root, ascending aorta, and aortic arch with endovascular stent-graft placement into the descending aorta. At three months of follow-up, he was asymptomatic and with no signs of target organ damage. Conclusions: A careful TTE scan is particularly important for asymptomatic AD patient because it most likely as a routine imaging technique used for cardiovascular evaluation. If miss-diagnosed and under-recognized by clinician, untreated patients with prolonged dissection will become highly susceptible to an aortic rupture or ischemia to organs and leads to mortality.
