Insights

Type A aortic dissection (TAAD) requires urgent surgery. This report details a novel strategy for managing carotid artery involvement in TAAD, achieving good neurological outcomes without total circulatory arrest.

Area of Science:

  • Cardiovascular Surgery
  • Neurology
  • Vascular Surgery

Background:

  • Type A aortic dissection (TAAD) is a life-threatening condition necessitating prompt surgical intervention.
  • Cerebral malperfusion complicates TAAD in 6-14% of cases, often due to dissection flap obstruction of arch vessels or embolic events.
  • Current literature lacks consistent management protocols for concurrent carotid artery dissection in TAAD patients.

Observation:

  • This case report focuses on a neurologically intact patient with TAAD and bilateral carotid artery involvement.
  • The described strategy aims to manage carotid artery issues within TAAD repair without resorting to total circulatory arrest (TCA).

Findings:

  • The presented easily replicable strategy successfully managed bilateral carotid artery involvement in TAAD.
  • The patient experienced a good neurological outcome, demonstrating the efficacy of the approach.
  • Avoidance of total circulatory arrest (TCA) was achieved during the intervention.

Implications:

  • This case suggests a viable and potentially safer alternative for managing complex TAAD cases involving carotid arteries.
  • The findings may contribute to developing standardized protocols for TAAD with concomitant carotid dissection.
  • This approach could improve neurological outcomes and reduce the risks associated with TCA in select TAAD patients.
