[Composite arterial conduits with internal thoracic artery and inferior epigastric artery for a myocardial revascularization].
From November 1992 to February 1995, 10 patients were submitted to myocardial revascularization using composite arterial conduit with internal thoracic artery (ITA) and inferior epigastric artery (IEA). The age ranged from 48 to 68 years (mean age, 60.3 years); all patients were male. All patients had double-or triple vessel disease. The mean ejection fraction was 61.8% (range, 43 to 77%). We used 28 arterial conduits including 5 right ITAs, 10 left ITAs, 10 IEAs, and 3 right gastroepiploic artery. 10 IEAs were anastomosed to one ITAs and 10 composite arterial conduits were constructed (branched in 3, lengthened in 7). In 5 patients a double ITAs were used in a single patient. There was no operative mortality and fetal complication. Early postoperative angiographic controls demonstrated 100% patency of composite grafts in 9 of 10 patients. The composite arterial graft using ITAs and IEAs is feasible and the anastomoses so performed are completely safe.
