Saphenous vein grafts (SVGs) are the most frequently used conduits in coronary artery bypass grafting (CABG), but their higher rate of occlusion compared to arterial conduits remains a concern.

A novel device called venous external support (VEST) may lead to increased longevity and durability of saphenous (leg) vein grafting during coronary artery bypass surgery, according to a multicenter trial coordinated by the Icahn School of Medicine at Mount Sinai.

VEST (venous external support; Vascular Graft Solutions [VGS]) is an external stent for use in coronary artery bypass graft (CABG) surgery in which at least 1 saphenous vein is used as the bypass conduit.

Nov 29, 2023 · The VEST device (Vascular Graft Solutions, Tel Aviv, Israel) is an external cobalt-chrome tubular support for SVGs during CABG with a braided structure composed of plastically deformable wires that can be shaped to the length and width of a vein graft.

Coronary artery bypass graft (CABG) surgery, the most commonly performed cardiac operation, has been shown to improve survival in appropriately selected patients with complex left main and/or multivessel coronary artery disease. 1 Major limitations of CABG surgery include graft failure, particularly with the use of saphenous veins, and ...

Feb 1, 2019 · We describe the preparation of the vein graft, selection of the appropriate VEST model, and the application procedure itself. We also present angiograms 2 years after coronary artery bypass grafting of unsupported versus VEST-supported saphenous vein grafts.

Nov 7, 2023 · Saphenous vein grafts (SVGs) are the most frequently used conduits in coronary artery bypass grafting (CABG), but their higher rate of occlusion compared to arterial conduits remains a concern.

Coronary bypass surgery (CABG) is the most performed cardiac surgery worldwide. However, both its short- and long-term outcomes are limited. VGS addresses CABGs’ biggest challenges – the poor longevity of vein grafts and procedure related neurological complications.

Oct 7, 2019 · Clinical data presented at the 2019 European Cardio-Thoracic Surgery (EACTS) annual meeting (3-5 October, Lisbon, Portugal), from two prospective trials of the VEST external stent for vein grafts during coronary artery bypass surgery (CABG), showed low major adverse cardiac and cerebrovascular events (MACCE) rates up to three years, excellent ...

Nov 23, 2021 · Coronary artery bypass surgery (CABG) is the most commonly performed cardiac operation, and improves survival in patients with complex left main and/or multi-vessel coronary artery disease. Surgeons commonly graft healthy saphenous veins onto arteries that feed the heart to bypass clogged vessels and restore blood flow.
