Gastroepiploic artery coronary bypass graft: non-invasive patency evaluation using color and duplex Doppler ultrasonography.
OBJECTIVE Color and duplex Doppler ultrasound and digital subtraction angiography were compared for the evaluation of graft patency of the gastroepiploic artery (GEA). METHODS In 77 observations, ultrasound and digital subtraction angiography were compared. The coronary resistance index (cRI) was defined as the maximal systolic flow velocity minus the maximal diastolic flow velocity, divided ...
متن کاملUnderstanding saphenous vein graft patency.
Saphenous vein was the conduit used in the first series of coronary surgery, and, with the exception of revascularization of the left anterior descending coronary artery, it remains the most commonly used conduit.1 There are several reasons for this. First, because of its relatively large diameter and wall characteristics, it is technically easy to use; second, it is plentiful, and therefore ca...
متن کاملThe Same Angiographic Factors Predict Venous and Arterial Graft Patency
To evaluate the value of angiographic factors in predicting failure of both venous and arterial coronary artery bypass graft. We retrieved from our angiographic database 148 patients who underwent venous and/or arterial CABG and for whom a control coronary angiography at more than 1 month after surgery was available. Pre-CABG and follow-up angiographies were analyzed in order to evaluate diamet...
متن کاملCoronary artery bypass graft patency and competitive flow.
ver since the observation by Loop et al. (1) that internal horacic arteries (ITA) are more effective coronary artery ypass grafts than saphenous veins in prolonging patient urvival and preventing recurrent ischemic events, cardiohoracic surgeons have tried to improve the results of urgical revascularization by using other arteries as bypass onduits, such as the gastroepiploic, radial, and infer...
متن کاملFactors affecting graft patency: the operating room and beyond.
Room and Beyond To the Editor: Zacharias and colleagues1 report improved survival with radial artery conduits versus vein graft in coronary artery bypass graft (CABG) surgery with left internal mammary artery to left anterior descending artery, as well as better radial patency. This study reinforces previous findings demonstrating superior patency of arterial conduits over vein grafts. Nonethel...
