[Late reoperations after repaired Stanford type A aortic dissection].

Area of Science:

• Cardiovascular Surgery
• Thoracic Surgery
• Aortic Dissection Management

Background:

• Stanford type A aortic dissection requires complex surgical repair.
• Late complications can necessitate reoperation after initial aortic surgery.
• Managing residual dissection and arch expansion presents significant challenges.

Purpose of the Study:

• To summarize reoperation experiences for late complications following Stanford type A aortic dissection repair.
• To evaluate outcomes and identify key surgical considerations for these complex cases.

Main Methods:

• Retrospective review of 14 patients undergoing reoperation for late complications of Stanford type A aortic dissection.
• Analysis of initial and reoperation procedures, including aortic root replacement (Bentall), ascending aorta replacement, and Sun's procedure.
• Assessment of perioperative data, complications, and follow-up outcomes.

Main Results:

• All 14 patients survived the reoperation, with one late death due to pulmonary infection.
• Postoperative complications included acute renal failure and pulmonary infection, all successfully treated.
• Follow-up showed no aortic rupture, paraplegia, or death, indicating favorable long-term results.

Conclusions:

• Reoperations for late complications of Stanford type A aortic dissection are technically demanding but feasible.
• The Sun's procedure is crucial for managing residual dissection and distal arch expansion.
• Meticulous surgical planning and execution are vital for successful outcomes in these high-risk reoperations.
