Summary

This case report details a rare instance of acute aortic dissection (Stanford type A) causing hemodynamic instability. Prompt cardiopulmonary bypass and brain protection during surgery are crucial for managing complex intimal flaps.

Area of Science:

  • Cardiovascular Surgery
  • Thoracic Surgery
  • Vascular Surgery

Background:

  • Acute aortic dissection (Stanford type A) is a life-threatening condition requiring prompt surgical intervention.
  • Complex intimal flap morphology can lead to severe hemodynamic compromise and neurological deficits.
  • Early diagnosis and management are critical for patient survival.

Observation:

  • A 43-year-old male presented with acute aortic dissection (Stanford type A).
  • The patient experienced hemodynamic collapse, ventricular fibrillation, and loss of consciousness prior to surgery.
  • Massive aortic regurgitation and coronary compromise resulted from intimal flap movement through the aortic valve.
  • A completely torn intimal flap intussuscepted into the brachiocephalic artery, potentially impairing cerebral perfusion.

Findings:

  • The patient's critical condition was attributed to a rare, complex intimal flap causing aortic regurgitation, coronary disturbance, and compromised cerebral perfusion.
  • The back-and-forth motion of the intimal flap through the aortic valve led to cardiogenic catastrophe.
  • Intussusception of a torn intimal flap into the brachiocephalic artery origin was observed.

Implications:

  • This case highlights the extreme rarity and severe consequences of complex intimal flaps in aortic dissection.
  • Immediate cardiopulmonary bypass is essential to support cardiac function upon diagnosis.
  • Surgical intervention must incorporate robust brain protection strategies for patients with complex aortic dissections.
