Novel device 'holds promise' for improving CABG outcomes

The device is designed to reduce complications in patients receiving saphenous vein grafts

A device to bolster the longevity of saphenous vein grafts in patients undergoing coronary artery bypass graft surgery is promising despite a recent trial failing its primary endpoint, the lead researcher says.

The VEST (venous external support) device is made of fine cobalt-chromium wire mesh and placed over the graft to prevent veins from dilating under pressure, thereby reducing intimal hyperplasia that can prompt repeat procedures.

“Vein grafts have a limited durability — about half of them will be closed 10 years after coronary bypass
