Area of Science:

  • Cardiovascular Surgery
  • Vascular Surgery
  • Thoracic Surgery

Background:

  • Aortic arch aneurysm repair carries high risks of mortality and morbidity.
  • Ensuring adequate brain protection is critical during these complex procedures.

Purpose of the Study:

  • To describe the experience of using a four-branched arch graft for aortic arch aneurysm repair.
  • To evaluate the safety and efficacy of this graft in protecting brain circulation.

Main Methods:

  • Surgical repair in six patients using a four-branched, polymer albumin-coated arch graft.
  • Deep hypothermic cardiopulmonary bypass (18-22°C).
  • Secondary arterial cannulation via the graft's fourth branch for continuous cerebral perfusion.

Main Results:

Related Experiment Videos

  • One hospital death occurred; no permanent neurological events were observed.
  • The four-branched graft facilitated anastomosis construction.
  • Continuous brain circulation was successfully maintained.

Conclusions:

  • The four-branched arch graft is a valuable tool for aortic arch aneurysm repair.
  • This technique enhances brain protection and may reduce neurological complications.
  • It simplifies surgical reconstruction of arch branch anastomoses.
