Extracorporeal Membrane Oxygenation in Stanford Type A Aortic Dissection

Area of Science:

• Cardiovascular Surgery
• Thoracic Surgery
• Critical Care Medicine

Background:

• Stanford type A aortic dissection (STAAD) is a life-threatening condition requiring complex surgical intervention.
• Postoperative complications, including refractory cardiogenic shock, can significantly impact patient outcomes.

Purpose of the Study:

• To summarize the clinical experience of using extracorporeal membrane oxygenation (ECMO) in patients with STAAD.
• To evaluate the efficacy and outcomes of ECMO support in this specific patient population.

Main Methods:

• Retrospective review of 246 acute STAAD patients operated between January 2012 and December 2016.
• Analysis of 7 patients who received postoperative veno-arterial ECMO via femoral cannulation.
• Detailed review of surgical procedures, ECMO duration, complications, and survival rates.

Main Results:

• All 7 patients received ECMO for refractory cardiogenic shock after ascending aorta replacement and total arch repair.
• Mean ECMO support duration was 244.5 hours; 85.7% of patients survived to discharge.
• Complications included bleeding requiring reoperation (2 patients) and transient delirium (1 patient).

Conclusions:

• ECMO serves as effective temporary cardiopulmonary support for STAAD patients experiencing postoperative cardiogenic shock.
• Proactive management of ECMO and its complications is crucial for enhancing patient survival.
• This study highlights the potential of ECMO to improve outcomes in complex aortic dissection cases.
