“…Multiple studies have replicated these findings, which indicates that early angiographic patency with radial artery grafts in the modern era consistently exceeds 90% and is similar to results achieved with the IMA. [7][8][9][10][11][12][13] In addition to these reports, the increasing acceptance of the radial artery has been based on 2 studies with angiographic results, both with 5 years of follow-up. In one, angiography in 50 patients with 64 radial grafts revealed a patency rate of 83%.…”

“…7 Multiple institutions have documented that the radial artery can be used with acceptable morbidity and mortality 8 -10 and that early angiographic results in the modern era approach those of the IMA. [7][8][9][10][11][12][13] This has led to a dramatic increase in the number of patients receiving radial artery bypass grafts. Yet, there are limited data on the later angiographic outcomes of these grafts.…”

“…Many institutions have reported that the RA can be used with acceptable mortality and morbidity rates and that the angiographical results are similar to those of the ITA [19][20][21][22][23][24][25][26][27]. On the other hand, some published data present limitations related to the long-term angiographical results of these grafts.…”

Artéria radial versus veia safena para revascularização do miocárdio: metanálise (não houve diferença estatisticamente significante)Radial artery versus saphenous vein to myocardial revascularization: meta-analysis (there is no statistically significant difference) AbstractObjective: To compare the effectiveness of the radial artery graft with the saphenous vein graft for myocardial revascularization in association with the internal thoracic artery.Methods: A systematic review of the literature was made, searching for articles in the MEDLINE and LILACS databases. Two independent researchers performed the selection of articles, carefully evaluating the methodology described in articles considered relevant to the subject. Only controlled trials with an adequate randomization system were included. In all situations, when the researchers did not reach an agreement, a consensus meeting was held. No restrictions were stipulated in respect to the follow-up period for the angiographic evaluation of the graft, the vessel treated or the characteristics of the patients included in the studies. The results are expressed as Relative Risks (RR), with 95% Confidence Intervals (CI) to compare the effectiveness between the radial artery and the saphenous vein.Results: Based on these criteria, three studies were included. We did not find statistical differences between the patencies of the grafts (RR 0.53 [95% IC 0. -2.18]).Conclusion: Despite the studies having good methodologies we did not observe statistically significant differences between the grafts. The statistical power of the meta-analysis is low and therefore, more randomized controlled trials are necessary, with adequate sample sizes to detect possible differences between the different treatments.Descriptors: Radial artery.

“…3). Examining the immediate postoperative graft patency is important because early occlusion may occur within the first week to month (a 10% likelihood in SVGs, 1% in LITA, 6% in RITA and 4 10% of radial grafts) and this is mainly due to spasm (23). Determining the etiology of ischemic symptoms after bypass graft surgery is an important clinical issue and it is essential for delivering proper management.…”

Purpose:We wanted to evaluate the utility of multi-slice computerized tomography (MSCT) for assessing coronary artery bypass graft patency and/or occlusion. Materials and Methods: For 24 patients, both conventional angiography and CT angiography with 4-MSCT were performed within seven days of one another in order to evaluate the accuracy of MSCT with regard to graft patency and/or occlusion. A follow-up CT angiogram was performed in patients with and without symptoms (n=11, n=34, respectively) with 4-or 16-MSCT. We retrospectively compared the results of MSCT to those of conventional coronary graft angiography. Results: Sixty-five grafts were evaluated for the accuracy of MSCT. Six of those 65 were occluded. The sensitivity, specificity, positive predictive value and negative predictive values of MSCT for the diagnosis of graft occlusion were 100% (6/6), 98% (58/59), 86% (6/7) and 100% (58/58), respectively. Patency could not be determined by angiography in two grafts; however, the grafts proved to be patent on MSCT. On follow-up, new graft occlusions in the asymptomatic patients were detected by MSCT in 8.2% of the previously patent grafts at the two years post-op, and in 15.2% at the three years post-op. Conclusion: MSCT is a practical and accurate noninvasive diagnostic tool for following up coronary artery bypass grafts.
