Blunt trauma can cause aortic transection, sometimes leading to unrecognized pseudoaneurysms. Radiographic findings are described to help diagnose these potentially fatal, yet often missed, conditions.

Area of Science:

  • Trauma Surgery
  • Vascular Surgery
  • Diagnostic Imaging

Background:

  • Aortic transection from blunt trauma has a low survival rate.
  • Survivors may develop unrecognized aortic pseudoaneurysms.
  • These pseudoaneurysms pose a risk of delayed rupture.

Purpose of the Study:

  • To describe radiographic findings suggestive of aortic pseudoaneurysm.
  • To aid in the diagnosis of post-traumatic aortic pseudoaneurysms.
  • To differentiate these from other mediastinal pathologies.

Main Methods:

  • Review of radiographic findings in patients with suspected aortic pseudoaneurysm.
  • Correlation of imaging features with clinical outcomes.
  • Description of characteristic imaging signs.

Main Results:

  • Specific radiographic features indicative of aortic pseudoaneurysm were identified.
  • These findings help distinguish pseudoaneurysms from hilar adenopathy, atherosclerotic aneurysms, and neoplasms.
  • Early recognition is crucial for timely intervention.

Conclusions:

  • Radiographic analysis is key to diagnosing unrecognized aortic pseudoaneurysms post-trauma.
  • Awareness of these findings can prevent misdiagnosis and delayed treatment.
  • Prompt diagnosis improves patient outcomes and reduces rupture risk.
