Peripheral vascular bypass (PVB) refers to the surgical revision of blood flow to restore perfusion distal to an occluded or otherwise disrupted arterial segment. PVB procedures can involve any of the arteries excluding those in the heart or the brain. These open surgical procedures are typically done by vascular surgeons, cardiologists, or interventional radiologists.
Peripheral artery bypass is surgery to reroute the blood supply around a blocked artery in one of your legs. Fatty deposits can build up inside the arteries and block them.
A graft is used to replace or bypass the blocked part of the artery. The graft may be a plastic tube, or it may be a blood vessel (vein) taken from your body (most often the opposite leg) during the same surgery.
