Insights

This study shows that combining aortic arch replacement with stent grafting effectively treats complex aortic dissection, achieving high rates of false lumen thrombosis with acceptable surgical risks.

Area of Science:

  • Cardiovascular Surgery
  • Thoracic Aortic Disease
  • Hybrid Surgical Techniques

Background:

  • Extensive thoracic aortic disease often requires complex surgical interventions.
  • Hybrid approaches combining open repair with endovascular techniques are emerging.
  • Complex aortic dissection (AD) presents significant management challenges.

Purpose of the Study:

  • To evaluate the early outcomes of a hybrid approach for extensive thoracic aortic disease.
  • To assess the efficacy of arch replacement combined with antegrade stent grafting in complex aortic dissection (AD).

Main Methods:

  • A multicentre retrospective study using an international registry.
  • 106 patients with complex AD (55 acute, 51 chronic) underwent hybrid repair using the E-vita open® stent graft.
  • Procedures involved hypothermic circulatory arrest (HCA) and selective antegrade cerebral perfusion (SACP).

Main Results:

  • Successful stent-graft deployment into the true lumen in 99% of cases.
  • High rates of thoracic false lumen (FL) thrombosis (93%) and thoraco-abdominal FL thrombosis (58%) at follow-up CT.
  • In-hospital mortality was 12%, with a 5% rate of new strokes.

Conclusions:

  • Combining arch replacement with downstream stent grafting offers a one-stage repair for complex AD.
  • This hybrid strategy achieves near-complete thoracic FL thrombosis.
  • The procedure can be performed with acceptable perioperative risk.
