Acute aortic dissection (AAD) is an uncommon clinical picture with a high mortality rate. Early diagnosis and treatment are important in decreasing the mortality. Clasically, AAD is characterized by a severe sudden onset pain of the chest, back, and abdomen. However, the patients with AAD may admit with a variety of different clinical findings as due to level of dissection in the aorta. In this study, our aim is to emphasize that the ADD rarely will cause gastrointestinal symptoms. In this paper, we reported a case of ADD caused acute pancreatitis, presenting in emergency department with abdominal pain.©2008, Ondokuz Mayis University, Medical Faculty.
