Tension-free left ITA graft -- the pericardial strip technique.

Emphysematous lung occupying the whole dome of the left pleural cavity and expanding well over the midline may occasionally present a significant problem for positioning of the left internal thoracic artery, although the graft has been mobilized up to its origin. To avoid an undue tension on it, we combined a well known technique of the pericardial incision with the pericardial strip technique, enabling the lung to expand freely.
