An experimental technique known as three-dimensional vascular ultrasound (3DVUS) estimates the quantification of plaque burden (in cubic millimeters) and can be used as an important addition to conventional risk factor profile in addressing patient risk stratification. // Peripheral artery disease
‘3-D Vascular ultrasound is a novel imaging technique for quantifying early carotid and femoral atherosclerosis which causes muscle pain and can be treated if detected early.’

Peripheral artery disease (also called peripheral arterial disease) is a common circulatory problem in which narrowed arteries reduce blood flow to your limbs. When you developperipheral artery disease (PAD), your extremities — usually your legs — don't receive enough blood flow to keep up with demand. Blocked blood flow to your legs can cause pain and numbness. It also can raise your risk of getting an infection in the affected limbs. Your body may have a hard time fighting the infection. If severe enough, blocked blood flow can cause gangrene (tissue death). In very serious cases, this can lead to leg amputation.
Researchers explored the bilateral carotid and femoral arteries of 3,860 middle aged participants without prior cardiovascular disease who were employees of the Banco de Santander in Madrid, Spain. This is an ongoing observational prospective cohort study where participants are being followed up for 10 years.
The 3DVUS examinations were performed using a new Phillips iU22 ultrasound system equipped with a VL13-5 3D volume-linear array transducer. This equipment will be available in the near future for routine patient care.
At an average age of 45 years, they found that the plaque burden in subjects was more than twice as high in men as in women (63.4 cubic millimeters vs. 25.7), and higher in the femoral arteries, and with increasing age.

"3DVUS is a feasible, reproducible, and novel imaging technique for quantifying early carotid and femoral atherosclerotic burden in large populations," said the study's lead author, Valentin Fuster, MD, PhD, Director of Mount Sinai Heart and Physician-in-Chief of The Mount Sinai Hospital.

P.A.D. increases your risk of coronary heart disease, heart attack, stroke, and transient ischemic attack ("mini-stroke"). Although P.A.D. is serious, it's treatable. If you have the disease, see your doctor regularly and treat the underlying atherosclerosis.
