[Management of the severe calcified ascending aorta during coronary bypass surgery]
Insights
Managing a calcified aorta during coronary surgery is challenging. The "Non-touch aortic technique" with femoral cannulation and hypothermia offers a safer approach for bypass surgery in these high-risk patients.
Area of Science:
- Cardiovascular Surgery
- Aortic Disease Management
Background:
- The optimal surgical strategy for patients with a calcified ascending aorta undergoing coronary artery bypass grafting (CABG) remains undefined.
- Atherosclerotic calcification of the ascending aorta poses significant risks, including cerebral embolism, aortic dissection, and rupture during aortic manipulation.
Observation:
- Two recent successful surgical cases involving severe aortic calcification were treated using the "Non-touch aortic technique."
- This technique avoids direct manipulation of the calcified aorta, mitigating risks associated with aortic clamping.
Findings:
- The "Non-touch aortic technique," combined with femoral artery cannulation and controlled hypothermia or circulatory arrest, was successfully employed.
- This approach effectively reduced the risks typically associated with operating on a calcified aorta.
Implications:
- This technique presents a viable and safer alternative for managing complex CABG cases with heavily calcified aortas.
- Further research and adoption of the "Non-touch aortic technique" could improve outcomes for patients with severe aortic calcification undergoing cardiac surgery.
Abstract:
The best management of the calcified ascending aorta during coronary surgery has not established. Clamping of the calcified aorta causes cerebral embolism, aortic rupture and laceration as a lethal complication. Recently we had two successful cases of surgical treatment and these were treated by "Non-touch aortic technique". The femoral cannulation and ventricular fibrillation with moderate hypothermia or circulatory arrest will reduce the risk of coronary bypass surgery in the calcified aorta.
