Mid-term patency of the inverted left internal thoracic artery conduit

In order to expand the revascularization of the left anterior descending coronary artery, we have applied the inverted left internal thoracic artery (left internal thoracic artery [LITA] transected near its origin, thus supplied by retrograde flow from superior epigastric and musculophrenic arteries) in carefully selected cases (four patients). The 64-slice multidetector row computed tomographic scans performed postoperatively (range, 6 to 40 days), as well as the scans performed in the follow-up period (range, 18 to 35 months) showed preserved inverted LITA conduits with thrombolysis in myocardial infarction (TIMI) 3 flow in all patients.
