Summary
This study introduces a novel 3D anastomosis technique for reconstructing the ascending aorta and aortic arch using artificial grafts. This method preserves the natural curvature, improving surgical outcomes for aortic reconstruction.
Area of Science:
- Cardiovascular Surgery
- Biomedical Engineering
- Anatomical Reconstruction
Background:
- The ascending aorta and aortic arch have a complex 3D curvature.
- Standard artificial grafts often fail to replicate this natural shape, potentially impacting function.
Purpose of the Study:
- To develop and evaluate a novel "3D anastomosis" technique for reconstructing the ascending aorta and aortic arch.
- To preserve the natural 3D curvature of these great vessels using artificial grafts.
Main Methods:
- Reconstruction of the ascending aorta and aortic arch using two separate artificial grafts.
- Creation of oblique incisions on graft stumps to facilitate a 90-degree twisted anastomosis.
- Surgical connection of grafts to form a 3D structure mimicking natural anatomy.
Main Results:
- Successful creation of a 3D form replicating the anatomical curve from the heart's right front to its left rear.
- Positive surgical outcomes observed in 14 patients who underwent this procedure.
Conclusions:
- The "3D anastomosis" technique effectively reconstructs the ascending aorta and aortic arch with artificial grafts.
- This method preserves the natural 3D curvature, offering a promising approach for aortic reconstruction.
