• This grading system is based on anatomical layers of the aortic wall—
  • intimal tear (grade I),
  • intramural hematoma (grade II),
  • pseudoaneurysm (grade III),
  • rupture (grade IV)—and directly influences the management of blunt aortic injuries.

Traumatic Pseudoaneurysm

This image represents a combination of plain film CXR and the correlative thoracic aortogram in a 38 year old patient, 13 years after an MVA. There is an aneurysmal bulge at the level of the isthmus, representing a traumatic aneurysm at the characteristic location of the ligamentum arteriosum. The P-A and lateral chest X-ray shows an enlarged and unusually shaped aortic knob and the angiogram confirms the pseudoaneurysm of the aorta. 35178c Courtesy of Laura Feldman MD. code CVS aorta artery

Abdominal Aorta


Acute Traumatic Dissection 

These images represent a traumatic dissection of the abdominal aorta caused by a compression injury to the abdomen. The angiograms in a and b shows what appears to be a complex tear of the aorta with a dissection and then a subtotal obstruction of the aorta distally. The CTscan shows (c) thedissection to better effect, with a subtotal narrowing of the aorta distally. Not also the injury of the left renal artery on the angiogram as well as the lack of perfusion of the left kidney on the CT scan.
