Unlike arteries, veins contain valves that prevent backward flow as blood travels against gravity, particularly in the legs. When these valves weaken or fail, circulation problems often develop.

Researchers are making ever more sophisticated mini organs in the lab — and now they can grow their own blood vessels. The ...

The LimFlow procedure allows doctors to convert a vein into a new artery that will supply fresh blood flow to the afflicted leg. Three out of four patients (76%) who underwent the procedure wound ...

Radial artery and saphenous vein patency more than 5 years after coronary artery bypass surgery: results from RAPS (Radial Artery Patency Study). J Am Coll Cardiol 2012;60:28-35.

For the first time, researchers have linked the hardening of arteries to blood clots in veins, a finding that could trigger new research in the effort to prevent the blockages that kill thousands ...

They treat arteries and veins in all parts of the body except for the heart and brain, which are handled by other specialists. Vascular surgeons are primarily concerned with matching the person to ...

How Arteries And Veins Develop In Parallel Pairs In The Embryo Date: May 26, 2008 Source: CNRS Summary: Using physical measurements, theoretical models and numerical simulations, researchers have ...

Surgeons can harvest arteries and veins from elsewhere in the patient’s body, but they’re in limited supply. Peripheral bypass grafts: Atherosclerosis can narrow arteries beyond the heart.

Angiography was performed at one year in 440 patients: 8.2 percent of radial-artery grafts and 13.6 percent of saphenous-vein grafts were completely occluded (P=0.009).
