Ligamentum Arteriosum Deceleration. 90% of blunt thoracic aortic injuries occur just distal to the aortic isthmus and are a result of deceleration injury from tethering to the ligamentum arteriosum. Patients often have multiple rib fractures, 1st and/or 2nd rib fractures, or other manifestations of severe.
The ductus arteriosus is a vessel. 90% of blunt thoracic aortic injuries occur just distal to the aortic isthmus and are a result of deceleration injury from tethering to the ligamentum arteriosum.
The Ligamentum Arteriosum Acts As A Tether That Holds The Aorta And Pulmonary Artery Close To Each Other.
It is second only to head injury as a global.
Aortic Rupture Can Occur From Multiple Causes, Which Include Blunt Aortic Injury Resulting From Rapid Deceleration, Penetrating Trauma, And Spontaneous Rupture Of Thoracic Or Abdominal Aortic Aneurysms.
With blunt trauma, the usual mechanism is a severe deceleration injury;
90% Of Blunt Thoracic Aortic Injuries Occur Just Distal To The Aortic Isthmus And Are A Result Of Deceleration Injury From Tethering To The Ligamentum Arteriosum.

During rapid deceleration trauma, such as from a vehicular collision, where is an aortic dissection most likely to occur?
With Blunt Trauma, The Usual Mechanism Is A Severe Deceleration Injury;
It tends to most commonly occur in the proximal descending aorta, near where the left subclavian artery branches off from the aorta.
