A passageway between two blood vessels or between two sides of the heart.
The passing of fluid through a channel which is not the usual one.
A channel which links two different blood vessels and carries blood from one to the other.
A medical technique that involves insertion of a bypass tube, or shunt, to allow fluid to flow freely past an obstruction or narrowing. For example, if a child has hydrocephalus, or excess fluid in the brain (as when a brain tumor blocks the flow of fluid), a shunt may be used to relieve possibly dangerous pressure. The procedure carries some risk of introducing infection, causing meningitis or ventriculitis (infection of the ventricles, the cavities in the brain where the fluid flows). As a child grows, a new shunt may need to be inserted; a a scan may be used to assess whether the shunt is working properly or needs replacement. One sign that a shunt is malfunctioning can be noisy, difficult breathing, called stridor.
To redirect the flow of a body fluid from one vessel to another. N. device implanted to redirect the flow of a body fluid.
An abnormal or surgically created passage between two usually unconnected body channels or cavities.
An abnormal or surgically created passage between two usually unconnected body channels or cavities. Shunting is surgical creation of a passage that is commonly performed to relieve hydrocephalus, an accumulation of fluid in the brain. In this procedure, da rain or shunt is implanted from the ventricle in the brain to the abdominal cavity to drain obstructed spinal fluid. The procedure prevents pressure buildup and consequent complications, such as brain damage, seizures, or blindness.
A passage connecting two anatomical channels and diverting blood from one to the other. It may occur as a congenital abnormality or be surgically created.
Passage of blood through a channel that is not its normal one. This may occur as a result of a congenital deformity or of surgery for example, a porto-caval shunt in which the main portal vein is joined up to the inferior vena cava.
A bypass, either naturally occurring or artificially created, is a pathway that redirects the flow of blood from one major route to another. This rerouting of blood circulation can occur to circumvent obstructions or to create alternative pathways for improved blood flow. Bypasses are commonly utilized in medical procedures to restore or enhance blood supply to specific areas of the body.
An anomalous connection between two body parts that are usually separate (as seen in a septal defect within the heart). The term also encompasses a surgically formed pathway between unrelated areas, often used for tasks like facilitating the drainage of surplus fluid.
