TUESDAY, Jan. 11 (HealthDay News) -- Use of an artery from the
arm rather than a vein from the leg doesn't lead to better outcomes
for coronary artery bypass graft (CABG) patients, according to a
U.S. researchers looked at angiographic patency -- which means
that the graft is open and unobstructed -- in more than 700
patients who underwent elective first-time CABG. The arm's radial
artery was used in 366 patients and the leg's saphenous vein was
used in 367 patients.
One year after the procedure, the patency rate in both groups
was 89 percent. In addition, there was no difference in the number
and types of adverse events, including serious adverse events,
according to the report published in the Jan. 12 issue of the
Journal of the American Medical Association.
"Although most clinicians assume that compared with vein grafts, arterial grafts have an improved patency rate, there are little multi-institutional prospective data on radial artery graft versus saphenous vein graft patency," Dr. Steven Goldman, of the Southern Arizona VA Health Care System and the University of Arizona Sarver Heart Center in Tucson, and colleagues wrote in a journal news release.
CABG is one of the most common surgeries done in the United
States, with more than 163,000 of the procedures performed in 2008
alone, according to background information in the study. The
success of the grafts depends on the long-term patency of the
arterial and venous grafts.
