Summary
A new surgical technique for total aortic arch replacement uses three grafts with deep hypothermic circulatory arrest and cerebral perfusion. This method offers a technically simple approach for secure vascular connections.
Area of Science:
- Cardiovascular Surgery
- Vascular Grafting
- Cerebral Perfusion
Background:
- Aortic arch replacement is a complex procedure.
- Ensuring adequate cerebral protection during aortic surgery is critical.
- Standardized techniques for total aortic arch replacement are continually evolving.
Purpose of the Study:
- To present a novel, technically simplified procedure for total aortic arch replacement.
- To evaluate the efficacy of deep hypothermic circulatory arrest and dual cerebral perfusion in this context.
- To demonstrate the creation of secure anastomoses in aortic arch reconstruction.
Main Methods:
- Total aortic arch replacement utilizing three separate Hemashield grafts.
- Implementation of deep hypothermic circulatory arrest (DHCA).
- Sequential application of continuous retrograde cerebral perfusion (RCP) followed by antegrade cerebral perfusion (ACP).
Main Results:
- The described surgical technique is technically straightforward to execute.
- The method facilitates the formation of secure vascular anastomoses.
- The combined use of DHCA and dual cerebral perfusion strategies proved effective.
Conclusions:
- This procedure offers a simplified and effective method for total aortic arch replacement.
- Secure anastomoses can be reliably achieved with this technique.
- The described perfusion strategy ensures adequate cerebral protection during aortic arch surgery.
