Modified mid-sternotomy approach for exposure of left internal mammary artery and the circumflex artery territory
1Milwaukee Heart Surgery Associates, Wisconsin, USA.
Insights
A modified mid-sternotomy incision improves surgical exposure for coronary artery bypass grafting. This technique enhances access to the left internal mammary artery and the heart's posterolateral surface, simplifying the procedure.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Surgical Techniques
Background:
- Coronary artery bypass grafting (CABG) is a prevalent cardiac surgery.
- Optimal surgical exposure of the left internal mammary artery (LIMA) and the circumflex-marginal artery system can be challenging during standard mid-sternotomy.
- Difficulties in exposure can complicate graft harvesting and anastomosis.
Purpose of the Study:
- To present a simple modification to the standard mid-sternotomy incision.
- To improve surgical access to the left internal mammary artery for easier harvesting.
- To enhance exposure of the left posterolateral cardiac surface for circumflex-marginal artery system grafting.
Main Methods:
- A modified mid-sternotomy incision technique is described.
- The modification aims to facilitate LIMA harvest and posterolateral cardiac access.
- No complex or cumbersome retractors are required.
Main Results:
- The described modification overcomes common exposure difficulties during CABG.
- It provides optimal access to the left internal mammary artery.
- It ensures adequate access to the left posterolateral cardiac surface.
Conclusions:
- The modified mid-sternotomy incision is an effective solution for improving surgical exposure in CABG.
- This technique simplifies critical aspects of the procedure, such as LIMA harvesting.
- It offers a low-complication approach to enhance surgical access without specialized equipment.
Abstract:
Despite coronary artery bypass grafting being a common operation today, obtaining an optimal exposure of the left internal mammary artery for its easy harvest can be difficult at times. Similarly, it may not always be easy to obtain adequate access to the left posterolateral surface of the heart (for the circumflex-marginal artery system). We describe a simple modification of the standard mid-sternotomy incision that helps to overcome both of these problems without using any cumbersome assembly of retractors and with minimal side effects.
