Acute and chronic thoracic aortic disease: surgical considerations

摘要

Acute thoracic aortic aneurysm (TAA) is the most life-threatening vascular disorder recognized to date. Aortic ruptures have an 80% mortality rate, with 50% of patients suffering death before reaching the hospital [1]. The risk of death from untreated type A dissections is 25%, 50%, 75%, and 90% at 24 hours, 2 days, 1 week and 1 month, respectively [2]. Due to their severity, all acute ascending aortic dissections require emergency surgery in order to prevent aortic rupture and death.
