This study details a successful open aortic technique for chronic dissecting aneurysms (DeBakey type II). The innovative approach involved hypothermia and selective brain perfusion, leading to positive patient outcomes.

Area of Science:

  • Cardiovascular Surgery
  • Vascular Surgery
  • Aortic Aneurysm Treatment

Background:

  • Chronic dissecting aneurysms, particularly DeBakey type II, present complex surgical challenges.
  • Traditional open aortic techniques require careful management of systemic circulation and organ perfusion.

Observation:

  • Two patients with chronic DeBakey type II dissecting aneurysms underwent surgical repair using an open aortic technique.
  • The procedure involved hypothermia to 23°C during proximal anastomosis and selective cerebral perfusion during lower body circulatory arrest for distal anastomosis.

Findings:

  • Successful graft replacement was achieved in both patients.
  • Anastomosis sites were located in the distal ascending aorta (case 1) and aortic arch (case 2).
  • Postoperative courses and angiograms were satisfactory, indicating successful repair and no immediate complications.

Implications:

  • The open aortic technique is a viable and effective option for DeBakey type II and potentially other types of aortic dissections (e.g., DeBakey type I).
  • This approach may be applicable to a broader range of aortic arch and ascending aorta pathologies.
  • The technique highlights the importance of controlled hypothermia and selective perfusion in complex aortic surgeries.
