Abstract:
Objective To investigate etiology and pathological morphological characteristics of sudden death caused by non-atherosclerotic aortic dissection. Propose accurate diagnosis of non-atherosclerotic aortic dissection by a proper method to autopsy. Methods A total of 8 cases of non-atherosclerotic aortic dissection from 2007 to 2015 were evaluated and analyzed in the present study. Results Non-atherosclerotic aortic dissection rupture is more common in men under the age of 40. It is lack of a typical clinical symptoms and had no marked history of hypertension. There are no related pathological changes of hypertension observed in autopsy. The pathological type is mainly DeBakey 1, in the main arteries,where it was found that decrease of elastic fibers and smooth muscle, cystic degeneration, inflammatory cell infiltration and other changes in media membrane. These changes were also found in the media arteries in 5 cases. Conclusion The etiology of non-atherosclerotic aortic dissection is complex, which is closely associated with many factors, such as genetics and inflammation. It affects the vessels systemically. In addition, systematic examination of large vessels is necessary as well as the examination of the middle arteries during autopsy. It is suggested that genetic tests are carried out for definite diagnosis.
