C51. Impending Rupture in Acute Type A Aortic Dissection : Case Report

Background Acute aortic dissection is a life threatening condition that remains a challenge to diagnose and treat. 67% patients was presented with Acute type A aortic dissection (ATAAD) and often accompanied with some complications. Case Summary A 40-year-old male with risk factor hypertension was presented with sudden sharp tearing-like chest pain and radiating to the back 3 hours before admission. He had transient decrease of consciousness and waken up spontaneously. He was compos mentis, with normal JVP, normal heart sound, no pulsus deficit, hypotension, cold acral and oliguria. He got fluid rehydration and the BP was stabilized. Haemoglobin was normal with increase D-Dimer. The ECG was normal and chest radiography revealed cardiomegaly and widening mediastinum. From eyeballing echocardiogram showed moderate pericardial effusion without right atrial and right ventricle collapse. A CT scan angiography was performed and revealed an Aortic Dissection Stanford A Debakey I. Discussion The development of an evidence-based strategy to rule out aortic dissection in patients presenting chest pain would be useful to diagnose patients with chest pain. Rapid diagnosis of dissection is most likely when CT is a part of the diagnostic testing. Hypotension and shock occurred in > 25% of patients with type ATAAD and in this patient was associated transient loss of consciousness. This patient was in impending rupture condition. The definitive treatment for this patient was emergency aortic repair surgery. We was succeded to stabilize the patient then referred to a cardiothoracic surgeon in 24 hours later.
