[Acute aortic dissection].

OBJECTIVE: Acute aortic dissection is a medical emergency associated with high rates of mortality. Despite recent diagnostic advances, prompt and accurate diagnosis is difficult. We present a review of the a medical emergency service experience to diagnosis, factors associated to prompt diagnosis and inhospital evolution.

MATERIAL AND METHOD: We studied 86 consecutive patients who had aortic dissections, to assess the presentation, management, and outcome.

RESULTS: Mean age 61.9 +/- 12.5 years, 80% male. Hypertension was the most common predisposing factor (65% of patients overall). Chest pain was the most common initial complaint (58%). The initial clinical impression was aortic dissection in 56% of patients overall. Computed tomography was diagnostic in 96% when used. 62% underwent surgery. Overall in-hospital mortality was 28%.

CONCLUSIONS: Acute aortic dissection presents with a wide range of manifestations. A high clinical index of suspicion and a prompt computed tomography should to improve recognition of aortic dissection.
