Repeat surgical intervention after aortic repair for acute Stanford type A dissection

Area of Science:

• Cardiovascular Surgery
• Thoracic Surgery
• Aortic Disease Management

Background:

• Acute Stanford type A aortic dissection requires complex surgical repair.
• Late complications can necessitate repeat interventions on the aorta and aortic valve.
• Evaluating outcomes of these repeat procedures is vital for patient management.

Purpose of the Study:

• To assess the early and mid-term outcomes of repeat surgical interventions for late complications following acute type A aortic dissection repair.
• To identify common reasons for repeat interventions and associated patient factors.

Main Methods:

• Retrospective review of hospital records for patients undergoing repeat aortic surgery between April 2011 and March 2017.
• Analysis of patient demographics, interval to repeat intervention, reasons for reoperation, and follow-up outcomes.

Main Results:

• 17 patients (mean age 62 years, 13 male) underwent repeat intervention.
• Common indications included residual type B dissection (10 patients), anastomotic pseudoaneurysm (5 patients), and aortic regurgitation (3 patients).
• No early or late mortality was observed during a mean follow-up of 3.3 years.

Conclusions:

• Repeat surgical intervention for complications after acute type A aortic dissection repair demonstrates favorable early and mid-term results.
• These interventions were not associated with early or late mortality.
• Regular long-term imaging and echocardiography are essential for early detection of residual type B dilatation, anastomotic pseudoaneurysm, and aortic regurgitation.
