Thoracodorsal artery as a free arterial graft for myocardial revascularization.

When complete arterial revascularization of coronary circulation cannot be accomplished using the internal thoracic artery and other conventionally used arterial conduits, the thoracodorsal artery may be an excellent alternative. We report the use of the thoracodorsal artery as a free arterial graft in 3 patients, describe the harvesting technique, and review the anatomy.
