Adult patients with long coarctation of the aorta (CoA) may require coarctectomy and prosthetic tube or patch implantation. Potential drawbacks of these techniques, such as risk of infection, thrombosis, neointimal ingrowth, and aneurysm formation, are closely related to the use of prosthetic materials.1-3
To avoid these specific risks, we developed a technique that includes resection of coarctation and two elements of plastic procedure: end-to-end suturing of the aorta posterior wall and patch closure of the longitudinally incised aorta anterior wall. The material for the patch is autologous left internal thoracic artery (LITA).
Technique
The approach is by left posterolateral thoracotomy through the fourth intercostal space. The length of the CoA and diameter of LITA are measured (Figure 1,
A). If the LITA diameter is big enough, then a segment of this vessel is harvested within the area between the second and third intercostal spaces. The arterial cylinder is opened longitudinally to prepare a patch (Figure 1, B). After harvesting, the
