Bilateral internal thoracic artery grafting: Long-term clinical and angiographic results of in situ versus Y grafts

Background: We evaluated whether bilateral internal thoracic arteries provide the same long-term results when used as in situ grafts and as Y grafts. Methods and Results: From October 1991 to February 2000, 1818 patients had bilateral internal thoracic arteries used as in situ (n = 1378, group A) or...

Zusammenfassung:Background: We evaluated whether bilateral internal thoracic arteries provide the same long-term results when used as in situ grafts and as Y grafts. Methods and Results: From October 1991 to February 2000, 1818 patients had bilateral internal thoracic arteries used as in situ (n = 1378, group A) or as Y grafts (n = 440, group B). The number of anastomoses per patient and the number of bilateral internal thoracic artery anastomoses per patient were higher in group B (3.1 ± 0.9 and 2.7 ± 0.9) than in group A (2.9 ± 0.8 and 2.2 ± 0.6) (both P
