This study reports a rare case of three-channeled aortic dissection in a patient with a history of thoracic aortic dissection. Intraoperative findings revealed an unexpected communication between dissection channels, highlighting a complex aortic pathology.

Area of Science:

  • Cardiovascular Surgery
  • Vascular Surgery
  • Aortic Disease

Background:

  • A 68-year-old woman with a 6-year history of DeBakey type III thoracic aortic dissection presented with chest pain.
  • Surgical intervention involved graft replacement of the descending thoracic aorta.

Observation:

  • Intraoperative assessment identified an unusual communication between the second and third channels of the dissected aorta.
  • This finding suggests a complex, multi-channeled dissection pattern.

Findings:

  • The patient's dissection was characterized as a 'three-channeled aortic dissection'.
  • The third dissection channel was located within the outer wall of the second channel.
  • A communication existed between the two false channels, a rare occurrence.

Implications:

  • This case adds to the limited literature on three-channeled aortic dissections.
  • Understanding these complex anatomical variations is crucial for surgical planning and patient outcomes.
  • Further research into the etiology and management of such rare dissections is warranted.
