“…Its diameter, usually close to 3 mm, allows for the performance of several sequential anastomosis without concern for luminal narrowing. This, combined with the hypothesis of greaterspasm when undergoing direct aoretic pressure, has led most surgeons to anastomosis the proximal RA to the LITA 1 . In our series, the RA was used in 51 patients (60%).…”

“…irect myocardial revascularization has also undergone several technical changes since it was first intro-duced. In 1968, Rene Favarolo and the Cleveland Clinic surgeons popularized the use of the greater saphenous vein as a bridge between the ascending aorta and the obstructed coronary arteries 1,2 . Initially proposed for the treatment of right coronary stenosis, saphenous vein grafts (SVGs) proved to be very versatile and were quickly adapted for D Correspondence to: Dr. Ali Abu Rumman Queen Alia Heart Institute, Amman; JORDAN.…”

Eighty-five patients underwent myocardial revascularization using artery grafts alone and were followed up for 30 months. Twenty-seven patients (31.7%) had single vessel disease, 28 patients (32.94%) had two-vessel disease and 30 patients (35.3%) had three or more obstructed coronary arteries. Eight of the patients had undergone previous surgical revascularization. The left internal mammary artery (LIMA) was routinely used for the left anterior descending branch (LAD). In 8 patients (9.4%), the in situ right internal mammary artery (RIMA) was used for revascularization of the right coronary artery (RCA) and its branches. The RIMA was sometimes used as a free graft from the aorta or as an artificial "Y" from the LIMA to the diagonal and marginal branches. We used the left radial artery (RA) as arterial conduit in 51 patients (60%). There were 2 intraoperative deaths. Hospital mortality was 9% (n=8). Of the fatal cases, 3 were redo surgeries, 3 underwent combined procedures (one for left ventricular aneyrysm, one for double valve replacement and one for mitral valve replacement) while only 3 of the fatal cases underwent revascularization as a primary and isolated procedure. It is concluded that complete arterial reconstruction carries an acceptably low operative mortality and excellent short-term follow-up. This strategy is particularly important for young patients to reduce the probability of future reoperation.

“…It is known, for example, about the effect of the degree of obstructive lesion of the target coronary on evolution of its flow [6,7]. However, only recently, other aspects of RA have been studied such as, for example, the different techniques for graft dissection or the site of proximal anastomosis [6,[8][9][10].…”

“…These works affirmed that, at least theoretically, arterial grafts were better than saphenous vein grafts as they presented lower occlusion rates over the long term. This has not been proven yet due to the short time that radial arteries and other arterial grafts have been employed [10,11].…”
