Ligamentum Arteriosum Deceleration. Tethering of the aorta by the ligamentum arteriosum makes the site. Ligamentum arteriosum (also known as ligament of botallo or harvey's ligament) is a fibrous remnant of the fetal ductus arteriosus (ductus botalli, botallo's duct).
The ligamentum arteriosum acts as a tether that holds the aorta and pulmonary artery close to each other. Deceleration forces such as those often sustained in automobile crashes are the most common cause of blunt aortic rupture as a result of the stress and strain placed on the aorta at the ligamentum arteriosum.
The Most Common Traumatic Aortic Injury Seen On Angiography (80%) Is A Laceration Just Distal To The Left Subclavian Artery At The Aortic Isthmus, Resulting In Development Of A Pseudoaneurysm.
The ligamentum arteriosum (or arteriosus) is the small fibrous remnant of the fetal ductus arteriosum, located between and connecting the proximal left pulmonary artery and the undersurface of the junction of the aortic.
Aortic Trauma Can Also Be Caused By Penetrating Traumas, Such As Stab Injury And Firearm Injury.
Most common location is isthmus (90%) just distal to the left subclavian artery.
The Ductus Arteriosus Is A Vessel.

Evaluation Of The Aorta At The Aortic Hiatus In The Diaphragm Should Also Be Conducted Because The Vessel Is Tethered At This Location And Therefore Susceptible To Rapid Deceleration Forces.
