Purpose

Peripheral vascular bypass surgery is performed to restore blood flow (revascularization) in the veins and arteries of people who have peripheral arterial disease (PAD), a form of peripheral vascular disease (PVD). People with PAD develop widespread...

hardening and narrowing of the arteries (atherosclerosis) from the gradual build-up of plaque. In advanced PAD, plaque accumulations (atheromas) obstruct arteries in the lower abdomen, groin, and legs, blocking the flow of blood, oxygen, and nutrients to the lower extremities (legs and feet). Rerouting blood flow around the blockage is one way to restore circulation. It relieves symptoms in the legs and feet, and helps avoid serious consequences such as heart attack, stroke, limb amputation, or death.

This animation describes percutaneous coronary interventions or PCIs. This procedure actually encompasses a number of diagnostic and therapeutic procedures such as angioplasty or balloon angioplasty. As the video describes, a catheter is inserted into the blood vessels and maneuvered into placed at the diseased portion of the coronary artery. A small balloon is inflated which opens the blocked artery. In most cases a coronary artery stent is left at the site to hold open the coronary artery.

Coronary Angiography

This video describes how the circulatory system works, how disease can affect blood vessels (atherosclerosis), and how doctors use angiography to test for coronary artery blockage.

What is ANGIOPLASTY and STENTING?

Sometimes used interchangeably, coronary angioplasty and stenting are actually two separate procedures. This video shows how coronary angioplasty and stenting are performed and how the two procedures differ.

How open abdominal aortic aneurysm surgery is carried out

Your aorta is the major artery leaving the heart, but extends to the abdomen. The video shows how a bulging out of the aorta (abdominal aortic aneurysm) is treated with a stent.

The Pacemaker of the Heart

Tiny electric currents flow through the heart muscle and cause them to contract, squeezing blood throughout the body. This animation shows the electrical system of the heart and how it is driven by a small patch of tissue called the cardiac pacemaker or sinoatrial node.

In this femoropopliteal bypass, a portion of the saphenous vein can be removed and used to bypass a portion of a diseased artery. To accomplish this, an incision is made down the inside of the leg (A). The saphenous vein is tied off from its tributaries and removed (B). An incision is made in the recipient artery (C), and the vein is stitched to it at the top and bottom of the leg (D). (Illustration by GGS Inc.)

Other Information

A peripheral vascular bypass, also called a lower extremity bypass, is the surgical rerouting of blood flow around an obstructed artery that supplies blood to the legs and feet. This surgery is performed when the buildup of fatty deposits (plaque) in an artery has blocked the normal flow of blood that carries oxygen and nutrients to the lower extremities. Bypass surgery reroutes blood from above the obstructed portion of an artery to another vessel below the obstruction.
