Traumatic aortic rupture: roentgenographic indications for angiography

Area of Science:

• Radiology
• Trauma Surgery
• Diagnostic Imaging

Background:

• The widened mediastinum on chest roentgenogram is a primary indicator for thoracic aortography after blunt chest trauma.
• Accurate identification of injuries is crucial for timely intervention and improved patient outcomes.

Purpose of the Study:

• To evaluate specific radiological findings on chest roentgenograms in patients with blunt thoracic trauma.
• To propose a refined set of indications for thoracic aortography in this patient population.

Main Methods:

• Retrospective analysis of 47 patients who underwent aortography post-blunt thoracic trauma.
• Comparison of 16 radiological findings on 100 cm AP supine chest roentgenograms with 100 trauma-free patients.
• Identification of significant indicators for aortography.

Main Results:

• Six radiological indications for thoracic aortography were identified:
• Mediastinum > 8 cm on 100 cm AP supine chest film
• Tracheal shift to the right
• Blurred aortic outline
• Obliterated left upper lobe apex medial aspect
• Opacified space between aorta and pulmonary artery
• Left main bronchus depression < 40 degrees.

Conclusions:

• The proposed six radiological indications can aid in the selective use of thoracic aortography following blunt chest trauma.
• These findings enhance the diagnostic pathway for potentially life-threatening thoracic aortic injuries.
