Summary
Open surgery for acute type B aortic dissection offers excellent durability with no false lumen patency or aortic expansion. Chronic dissections treated with open surgery may experience false lumen patency and aortic expansion.
Area of Science:
- Cardiovascular Surgery
- Vascular Surgery
- Thoracic Surgery
Background:
- Surgical approaches for type B aortic dissection have evolved.
- This study reviews single-center surgical experience with type B aortic dissections.
- Compares current data with findings from other institutions.
Purpose of the Study:
- To evaluate the outcomes of open surgery for type B aortic dissections.
- To compare results between acute and chronic dissections.
- To assess long-term durability and complications.
Main Methods:
- Retrospective review of 29 patients undergoing surgery for type B aortic dissection (14 acute, 15 chronic) between 1996 and 2004.
- Data collected included patient demographics, surgical details, and immediate/late outcomes.
- Follow-up duration averaged 36 months.
Main Results:
- Hospital mortality was 4 patients. Mean ICU stay was 4.2 days.
- False lumen patency rates at 24 months were 16.7% for acute and 46% for chronic dissections (p<0.05).
- Chronic dissections with distal anastomoses involving both lumens showed higher false lumen patency and required reoperation in 3 cases.
Conclusions:
- Open surgery for acute type B aortic dissection demonstrates excellent long-term durability with no false lumen patency or aortic expansion.
- In chronic type B aortic dissections, incorporating both true and false lumens in distal anastomosis led to false lumen patency and aortic expansion.
