Radial Artery, Saphenous Vein Yield Same Results After CABG

Radial artery graft does not yield greater one-year patency than saphenous vein post CABG

TUESDAY, Jan. 11 (HealthDay News) -- Using a radial artery graft instead of a saphenous vein graft in patients undergoing elective coronary artery bypass graft (CABG) surgery does not result in greater one-year patency, according to research published in the Jan. 12 issue of the Journal of the American Medical Association.

Steven Goldman, M.D., of the Southern Arizona VA Health Care System in Tucson, and colleagues conducted a prospective, randomized trial from February 2003 to February 2009 of 733 patients, mostly men, undergoing first-time elective CABG. Study findings were based on 533 patients who had angiograms between two and 24 months after CABG.

The researchers found that there was no significant difference in graft patency at one year after CABG: 89 percent in both the radial artery and saphenous vein groups. There were also no significant differences between the two groups in angiographic graft patency at one week after CABG, myocardial infarction, stroke, repeat vascularization, and death.

"Among patients undergoing first time elective CABG, the use of a radial artery graft compared with saphenous vein graft did not result in greater one-year patency," the authors write.
