Influence of coronary territory on flow profiles of saphenous vein grafts
BACKGROUND Differing perfusion of the left and right ventricular coronary territory may influence flow-profiles of saphenous vein grafts (SVGs). We compared flow parameters, measured by transit-time flowmetry (TTFM), in left- and right-sided SVGs during coronary artery by-pass grafting (CABG). METHODS Routine TTFM measurements were obtained in 167 SVGs to the left territory (55%) and 134 SVGs...

Letter by Doraiswamy Regarding Article, “Vascular Reactivity and Flow Characteristics of Radial Artery and Long Saphenous Vein Coronary Bypass Grafts: A 5-Year Follow-Up” To the Editor: Webb et al described the flow response to endothelial acting agents in their study on radial artery and saphenous vein grafts.1 The superiority of radial artery over saphenous vein grafts is well supported by th...
متن کاملRemodeling leads to distinctly more intimal hyperplasia in coronary than in infrainguinal vein grafts.
BACKGROUND Flow patterns and shear forces in native coronary arteries are more protective against neointimal hyperplasia than those in femoral arteries. Yet, the caliber mismatch with their target arteries makes coronary artery bypass grafts more likely to encounter intimal hyperplasia than their infrainguinal counterparts due to the resultant slow flow velocity and decreased wall stress. To al...
متن کاملVascular reactivity and flow characteristics of radial artery and long saphenous vein coronary bypass grafts: a 5-year follow-up.
BACKGROUND Radial artery (RA) aortocoronary bypass grafts anastomosed to a branch of the circumflex coronary artery have significantly better patency rates than saphenous vein (SV) grafts at 5 years, but the physiological characteristics and mechanisms involved are not clearly defined. We compared RA and SV graft vasomotor and flow responses to endothelium-dependent and -independent stimuli 5 y...
