The subscapular artery: an alternative conduit for coronary bypass.

The search for an alternative conduit for coronary bypass has prompted our use of the subscapular artery for coronary bypass via a left thoracotomy in three patients. Historically, this artery in conjunction with muscle flaps has been used successfully as a free graft. Its size and length have proved feasible for coronary bypass to the circumflex coronary artery system. All three patients have had excellent clinical results lasting from 6 to 21 months.
