Summary

Thoracic aortic aneurysms, often from arteriosclerosis, can have various causes. Computed tomography (CT) is crucial for evaluating these aneurysms, assessing complications, and guiding treatment.

Area of Science:

  • Radiology
  • Cardiovascular Imaging
  • Thoracic Surgery

Background:

  • Aneurysms of the thoracic aorta arise from diverse causes, predominantly arteriosclerosis, but also genetic conditions like Marfan syndrome, dissection, trauma, infections, and congenital anomalies.
  • Understanding the normal anatomy of the thoracic aorta is fundamental for accurate diagnosis and management of aortic pathologies.

Purpose of the Study:

  • To review the normal anatomy of the thoracic aorta.
  • To detail the technique and interpretation of computed tomography (CT) for evaluating thoracic aortic aneurysms.
  • To illustrate the CT appearance of various aortic aneurysms and their complications.

Main Methods:

  • Review of normal thoracic aorta anatomy.
  • Detailed description of computed tomography (CT) imaging protocols and interpretation criteria for thoracic aortic aneurysms.

  • Illustration of CT findings for different aneurysm types, complications, and differential diagnoses.

    • Main Results:

    • Computed tomography (CT) provides comprehensive evaluation of thoracic aortic aneurysms, including morphology, extent, and relationship to surrounding structures.
    • CT is effective in identifying aneurysm complications such as rupture, dissection, and thrombus formation.
    • CT aids in differentiating aortic aneurysms from other paraaortic masses and is valuable for postoperative surveillance.

    Conclusions:

    • Computed tomography (CT) is an indispensable tool for the diagnosis, characterization, and management of thoracic aortic aneurysms.
    • CT facilitates accurate assessment of aneurysm etiology, complications, and guides surgical or medical treatment strategies.
    • Postoperative CT monitoring is essential for evaluating treatment efficacy and detecting potential complications or disease recurrence.
