Summary

Interventional therapy using stent-grafts offers a safe and effective alternative for thoracic aorta lesions. Careful planning with CT angiography is crucial for successful outcomes in patients with thoracic aortic aneurysms and dissections.

Area of Science:

  • Cardiovascular Surgery
  • Interventional Radiology
  • Vascular Medicine

Background:

  • Thoracic aorta lesions, including aneurysms and dissections, pose significant risks.
  • Traditional surgical repair can be associated with high morbidity and mortality.
  • Minimally invasive endovascular techniques are emerging as alternatives.

Purpose of the Study:

  • To determine the conditions for successful acute and long-term results of interventional therapy for thoracic aorta lesions using stent-grafts.
  • To evaluate the safety and feasibility of percutaneous stent-graft repair in complex thoracic aorta pathologies.

Main Methods:

  • Retrospective evaluation of 51 patients with thoracic aorta pathologies (aneurysms, type B dissections, rupture, aortobronchial fistula).
  • Interdisciplinary discussion involving thoracic surgeons and interventional radiologists.

  • Pre-procedural multidetector row CT angiography for planning.
  • Stent-graft implantation performed under general anesthesia in a DSA suite.

    • Main Results:

    • Successful stent-graft implantation in 29 out of 31 attempted cases.
    • Indications included thoracic aorta aneurysms (29), type B dissections (21), perforations (19), and aortobronchial fistula (1).
    • Complications included two cases of endoleaks treated with secondary stent-graft placement and one iliacal dissection managed surgically. One peri-procedural death occurred due to cardiac failure.

    Conclusions:

    • Percutaneous stent-graft treatment is a safe and feasible alternative to surgical repair for descending thoracic aorta lesions.
    • Multidetector row CT angiography is essential for precise planning of endovascular interventions.
    • Careful patient selection and procedural planning are key to optimizing outcomes.
