Summary
Type A aortic dissection surgery is increasing, with high mortality and morbidity rates. However, operative mortality has decreased since 2014, and prognosis is good after surviving the perioperative period.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Aortic Disease
Background:
- Type A aortic dissection is a life-threatening condition requiring immediate surgical intervention.
- Understanding contemporary trends and outcomes is crucial for improving patient care.
Purpose of the Study:
- To review trends, patient characteristics, surgical outcomes, and predictors of mortality and morbidity for Type A aortic dissection.
- To analyze a 14-year surgical experience at a single center.
Main Methods:
- Prospective data collection on consecutive patients undergoing Type A aortic dissection surgery from March 2003 to March 2017.
- Statistical analysis of patient demographics, preoperative status, operative details, and outcomes.
Main Results:
- 327 patients were included; surgeries increased significantly after 2010.
- Operative mortality was 19.9%, decreasing to 14.0% since 2014.
- Critical preoperative state and malperfusion syndrome independently predicted adverse outcomes.
Conclusions:
- Surgery for acute Type A aortic dissection is increasing, with persistent high morbidity.
- While operative mortality has decreased, critical preoperative state and malperfusion remain key predictors of adverse outcomes.
- Patients surviving the perioperative period have a favorable long-term prognosis.
