Current Opinion in Cardiology, 1994
In spite of their limited long-term patency, saphenous vein grafts continue to be widely used in patients undergoing coronary artery bypass surgery. Careful surgical technique reduces to some extent the vascular endothelial damage occurring during surgery.

Early and Late Patency of Aortocoronary Vein Grafts
Scandinavian Journal of Thoracic and Cardiovascular Surgery, 1981Early patency (two weeks) of 331 aortocoronary vein grafts was 89%. Late patency (one year) of 122 restudied grafts was 80%. A cumulative one year patency of 72% was calculated. Patency was similar for SV grafts, sutured distal to stenosis and segmental obstruction. Early patency was significantly decreased when the peroperative graft blood flow was 20

Factors Influencing Patency of Saphenous Vein Grafts
The Annals of Thoracic Surgery, 1979To determine factors affecting saphenous vein graft patency, 218 grafts in 66 unselected patients were studied angiographically 1 year after operation. Fourteen variables were extracted from the angiograms, electrocardiograms, and intraoperative flow measurements to assess their predictive value.

Long-term patency of polytetrafluoroethylene graft fistulas
The American Journal of Surgery, 1988Polytetrafluoroethylene grafts have been the mainstay for hemoaccess at our dialysis unit since 1976. Of 528 grafts placed in the forearm, 81 were evaluated for long-term patency and complication rates. When appropriate diagnostic studies and clinical signs delineate the cause of graft problems, a variety of surgical techniques can be used to maintain ...

Recruitable patency of the internal mammary artery graft
Catheterization and Cardiovascular Interventions, 2001A 46-year-old man underwent two coronary bypass operations and three percutaneous interventions over a period of 18 years. A non-functioning internal mammary artery (IMA) graft, was observed shortly after the second surgery. This graft was anastomosed to the left anterior descending (LAD) that had adequate flow from an older vein graft placed during ...

Arteriovenous graft patency outcomes and prognostic factors
Vascular, 2018Objectives Arteriovenous graft for hemodialysis shows poorer outcomes than arteriovenous fistula, due to frequent stenosis and thrombosis. We investigated arteriovenous graft patency outcomes and prognostic factors for these outcomes. Methods

Microvascular Vein-Graft Patency in the Rat Model
Journal of Reconstructive Microsurgery, 1994This study establishes a controlled model, to examine the patency rates of simple, arterial and venous anastomoses, compared to vessel repairs performed with 10-mm, size-matched, interpositional, vein grafts in the rat femoral artery and vein. Patency rates in two control groups, consisting of 68 Sprague-Dawley rats in which simple, femoral-vessel ...

Mediastinal wound infection and aortocoronary graft patency
The American Journal of Surgery, 1976In our experience, eight of ten aortocoronary grafts in five patients remained patent in the face of mediastinal infection. Combining reports of seventeen other grafts from the literature, we conclude that patency can be anticipated in approximately 70 per cent of such grafts and that mediastinal infection does not necessarily adversely affect ...

One-Year Patency of Valvulotomized Vein Grafts Is Similar to That of Arterial Grafts
The Thoracic and Cardiovascular Surgeon, 2015Inferior vein graft patency after coronary artery bypass grafting (CABG) is attributed to various factors. Venous valves may limit flow, cause thrombus formation, and diminish diastolic backflow. The aim of our study was to compare clinical outcome and midterm patency rate of valvulotomized vein grafts and arterial grafts in patients undergoing CABG ...

Prolonging Patency — Choosing Coronary Bypass Grafts
New England Journal of Medicine, 2004The benefits of coronary bypass surgery last only as long as the grafts continue to function, notes Dr. Bruce W. Lytle. He discusses the important differences among coronary bypass grafts.
