Travel agents or agencies must have an identifying number called an IATA, or International Air Transport Association, number to work with travel suppliers such as tour operators and airlines. Having IATA accreditation simplifies the business relationship between travel suppliers and travel agents.
Shunt (medical) In medicine, a shunt is a hole or a small passage which moves, or allows movement of, fluid from one part of the body to another. The term may describe either congenital or acquired shunts; and acquired shunts (sometimes referred to as iatrogenic shunts) may be either biological or mechanical.
A liver shunt is a blood vessel that carries blood around the liver instead of through it. In some animals a liver shunt is a birth defect (congenital portosystemic shunt).In others, multiple small shunts (acquired portosystemic shunts) form because of severe liver disease such as cirrhosis. portogram is an x-ray of the blood vessels to the liver. Because blood vessels are not easily seen on regular x-rays, a contrast material (a liquid that looks white on x-rays) must be injected into a blood vessel in the abdomen.
