Acute type A aortic dissection (TA-AAD) is a highly lethal clinical entity that can occur within a wide age range, associated with multiple aetiologies and various clinical presentations. In the very elderly type A aortic dissection frequently presents with non-specific symptoms and signs and is associated with high mortality and morbidity. Thus the clinician must have a high index of clinical suspicion in order to prompt the most appropriate diagnostic-therapeutic strategy. We report a nonagenarian women with TA-AAD, treated successfully with medical therapy.
