Acute Thoracic Aortic Dissection Emergency Medicine Guideline [v1.0]
McCabe, Aileen; Gray, James; Moore, David
Thoracic aortic dissection (AD) is a rare but potentially fatal event resulting in separation of
the layers of the tunica media by ingress of blood, producing a false lumen with variable
proximal and distal extension.
AD can be challenging to diagnose. A high index of suspicion is required due to the high
mortality rate. It is essential to get early senior help and radiology assistance.
