Acute aortic syndrome Microchapters |
Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]Associate Editor(s)-in-Chief:
Overview
Acute aortic syndrome (AAS) describes a constellation of emergency conditions with a similar clinical feature that involves the aorta.[1] These include aortic dissection, intramural thrombus, and penetrating atherosclerotic aortic ulcer.[2] It is possible for AAS to lead to acute coronary syndrome.[3] The term was introduced in 2001.[4][5]
Classification
Acute aortic syndromes is classified into 5 entities as follows:[6][7]
- Type I: classic aortic dissection involving an intimal layer between the true and false lumen (with no communication between the two lumen)
- Type II: aortic dissection with medial rupture and the subsequent intramural hematoma formation
- Type III: Subtle aortic dissection with bulging of the aortic wall
- Type IV: aortic dissection due to plaque rupture and subsequent ulceration
- Type V: iatrogenic/traumatic dissection
Causes
Causes include aortic dissection, intramural hematoma, penetrating atherosclerotic ulcer or a thoracic aneurysm that has become unstable.[8] Basically, AAS can be caused by a breakdown on the wall of the aorta that involves the tunica intima and/or media.[9]
Diagnosis
The condition can be mimicked by a ruptured cyst of the pericardium,[10] ruptured aortic aneurysm[11] and acute coronary syndrome.[12]
Misdiagnosis is estimated at 39% and is associated with delays correct diagnosis and improper treatment with anticoagulants producing excessive bleeding and extended hospital stay.[12]
Management
AAS is life-threatening, with a high mortality rate if appearing acutely, reduced only when diagnosed early and treated by a surgeon with considerable expertise.[9] If patients survive acute presentation, within three to five years 30% will develop complications and require close follow-up.[9] Early diagnosis is essential for survival and management is challenging though greater awareness of the syndrome and improving management strategies are improving patient outcomes.[13]
