A technique to protect the left internal thoracic artery.

Author information

  • 1Parkland Memorial Hospital, Dallas, Texas, USA.


The natural tendency of the harvested in-situ left internal thoracic artery is to assume a position near the anterior midline of the mediastinum, adjacent to the posterior sternal table. This repositioning of the left internal thoracic artery makes sternal reentry for redo myocardial revascularization (or other open cardiac procedures) hazardous. A technique of posterior and lateral repositioning of the mobilized in-situ left internal thoracic artery by creating a thymic flap and a pleuromediastinal groove is presented.
