background
Background
  • Hybrid (1st stage: open surgical + 2nd stage: endovascular) repairs of complex arch diseases are feasible and effective
  • Optimal technique (elephant trunk vs. arch debranching) for creation of a suitable proximal landing zone for endovascular repair remains undecided
elephant trunk
Elephant Trunk
  • Advantages:
    • Long, prosthetic proximal landing zone
    • Single stage option
  • Disadvantages:
    • Mobile, unsupported structure
    • Difficult to access
    • Uncertain long-term stability
arch debranching
Arch Debranching
  • Advantages:
    • Long, native proximal landing zone
    • Single stage option
  • Disadvantages:
    • A short, dilated ascending aorta may require ascending replacement and/or trans-valvular insertion
    • 3-vessel debranching can be challenging
    • Risk of ascending dissection
objective methods
Objective & Methods

Arch Debranching vs. Elephant Trunk

+

Endovascular Stent Graft

  • Retrospective review of consecutive patients with proximal thoracic aortic pathologies
  • Prospective database, imaging, medical records
  • Categorical variables were compared using Fisher’s exact test. Continuous variables with nonparametric distribution were compared using the Mann-Whitney U test. A p-value <0.05 was considered significant.
conclusions
Conclusions
  • Arch debranching was associated with:
    • Less frequent need for CPB/circulatory arrest
    • Shorter overall LOS
    • Earlier 2nd stage completion
    • One-third the incidence of proximal endoleaks
