Acute Aortic Syndromes.

Acute aortic syndromes, classified into aortic dissection, intramural hematoma, and penetrating aortic ulcer, are associated with high early mortality for which early diagnosis and management are crucial to optimize outcomes. Patients often present with nonspecific clinical symptoms and signs; therefore, it is important for providers to maintain a high index of suspicion for acute aortic syndromes. Electrocardiogram-gated computed tomographic angiography of the chest, abdomen, and pelvis is currently the most practical imaging modality for diagnosis and identification of complications. Evolution in surgical techniques and the development of aortic endografts have improved patient outcomes, but randomized trials are still needed.
