Background We investigated the impacts of flow demand and native coronary stenosis on
graft flow and patency. Methods We reviewed the angiograms of 549 bypass grafts in 301 …

Objective: To characterise the prognostic value of intraoperative ultrasonic graft flow
determination during CABG for mid-term patency. Methods: From 01/2000 to 08/2003 3146 …

To determine factors affecting saphenous vein graft patency, 218 grafts in 66 unselected
patients were studied angiographically 1 year after operation. Fourteen variables were …

Poor long-term patency of saphenous vein grafts limits the long-term success of the coronary
artery bypass operation. If this is to be improved, either measures that increase the patency …

Background Coronary artery bypass grafting (CABG) using saphenous vein grafts (SVG) is
vitiated by poor long-term patency of the vein grafts. Pedicled SVG harvested with the “no …

Background previous studies evaluating external stents for saphenous vein grafts (SVG) in
CABG were limited to on-pump isolated CABG and single grafting technique with one …

OBJECTIVE: This trial aimed to determine whether intraoperative graft assessment with
criteria for graft revision would decrease the proportion of patients with 1 or more graft …

Objectives To undertake a systematic review and meta-analysis of cohort studies to compare
the patency and adverse outcomes of sequential and individual saphenous vein grafts …

BACKGROUND: To avoid complications related to aortic manipulation, devices were
developed to perform clampless anastomosis. However, there are few studies concerning …

Introduction: Conduit size and quality are major determinants of the long-term success of
infrainguinal autologous vein grafting. However, accurate measurement of the internal …
