Thoracoabdominal aortic surgery (TAAA)

Thoracoabdominal aortic surgery (TAAA)


An aneurysm is a problem that primarily affects the aorta. An aneurysm is a blood vessel that has enlarged beyond its normal size. Aortic aneurysms usually occur in five distinct areas:

  • Thoracoabdominal aorta
  • Abdominal aorta
  • Ascending aorta and aortic root
  • Aortic arch
  • Descending aorta

Surgery in the thoraco-abdominal aorta (TAAA) may involve various segments of the aorta from the left subclavian to the aortic bifurcation.

Our physicians have the most current knowledge of state-of-the-art diagnostic, anesthesiological, surgical and endovascular tools for TAAA. Due to the technological innovations of the last few decades, open surgery on thoracoabdominal aortic aneurysms has improved significantly, especially regarding organ sparing. 


Thoracoabdominal aortic disease is being diagnosed more frequently as the population ages and as increasingly more sophisticated noninvasive imaging technology and techniques evolve. The two preferred diagnostic tools are:

  • Computed tomography (CT) scan, the most frequently used diagnostic tool
  • Trans-thoracic echocardiography, an equally noninvasive screening method


Complications can include spinal cord ischemia (reduced blood flow to the spinal cord), paraplegia (paralysis of legs and lower body), but several innovative techniques reduce these risks.
