Cases Report of Atypical Aortic Dissection

Background: Aortic dissection (AD) is one of the common causes of fatal chest pain in emergency medicine. The main and most common clinical manifestation is pain, with about 90% of patients experiencing sudden persistent, tearing or cutting-like pain in the chest or back. However, there have also been reports of myocardial infarction, heart failure, renal failure, syncope, shock, stroke, paraplegia and other cases. Clinical misdiagnosis is common. Aim: Alert clinicians to aortic dissection with shock and chest tightness as the main clinical presentations. Case Presentation: Report on two cases of aortic dissection with syncope and shock as the main manifestations. Conclusion: Aortic dissection is a highly dangerous cardiovascular emergency with a high mortality rate. In clinical practice, awareness of the clinical manifestations of aortic dissection should be increased. Careful inquiry about medical history, attention to atypical clinical presentations of aortic dissection, thorough physical examination, and comprehensive diagnostic evaluation can improve the success rate of diagnosing aortic dissection.
