==Overview==
==Overview==
'''Acute aortic syndrome''' ('''AAS''') describes a constellation of emergency conditions with a similar clinical feature that involves the [[aorta]]. These include [[aortic dissection]], intramural [[thrombus]], and [[penetrating atherosclerotic ulcer|penetrating atherosclerotic aortic ulcer]]. It is possible for AAS to lead to [[acute coronary syndrome]]. The term was introduced in 2001.
'''Acute aortic syndrome''' ('''AAS''') describes a constellation of emergency conditions with a similar clinical feature that involves the [[aorta]]. These include [[aortic dissection]], intramural [[thrombus]], and [[penetrating atherosclerotic aortic ulcer]]. It is possible for AAS to get complicated by [[acute coronary syndrome]]. The term was introduced in 2001.

Overview

Acute aortic syndrome (AAS) describes a constellation of emergency conditions with a similar clinical feature that involves the aorta. These include aortic dissection, intramural thrombus, and penetrating atherosclerotic aortic ulcer. It is possible for AAS to get complicated by acute coronary syndrome. The term was introduced in 2001.

Classification

Acute aortic syndrome is classified into 5 entities as follows:[2][3]

  • 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

History and clinical assessment
I B [7]
Laboratory testing
  • "In case of suspicion of AAS, the interpretation of biomarkers should always be considered along with the pretest clinical probability."
IIa B
  • "In case of low clinical probability of AAS, negative D-dimer levels should be considered as ruling out the diagnosis."
IIa C [8][9][10][11]
  • "In case of intermediate clinical probability of AAS with a positive (point-of-care) D-dimer test, further imaging tests should be considered."
IIa B [8][9]
  • "In patients with high probability (risk score 2 or 3) of AD, testing of D-dimers is not recommended."
III C
Imaging
  • "TTE is recommended as an initial imaging investigation."
I C
  • "In unstabled patients with a suspicion of AAS, the following imaging modalities are recommended according to local availability and expertise:
TOE" I C
CT I C
  • "In stable patients with a suspicion of AAS, the following imaging modalities are recommended (or should be considered) according to local availability and expertise:
CT I C
MRI I C
TOE" IIa C
  • "In case of initially negative imaging with the persistence of suspicion of AAS, repetitive imaging (CT or MRI) is recommended."
I C
  • "Chest X-ray maybe considered in cases of low clinical probability of AAS."
IIb C
  • "In case of uncomplicated Type B AD treated medically, repeated imaging (CT or MRI)e during the first days is recommended."
