What is a short circuit?

In medicine, Shunt has two related definitions. In both cases it is a passage that is usually not present in the body, which allows fluid communication between two areas. It can either be a congenital condition that represents the initial abnormality of the body and creates a medical dysfunction, or it can be what is called the created or acquired condition, which is used to compensate for a type of health problem. There are many examples of both clusters. Congenital bends may occur in many different areas of the body. Some of the best known relate to congenital heart defects and are basically holes that exist between two parts of the heart that are usually closed apart. The holes in the chamber and the atrial septum may be problematic because they result in a blood shift between the right and left ventricles or atrial, which can either increase the pressure in the chambers or send the blood -backed blood back to the body.

Not all bends are abnormal. People were born with a few small holes in the heart notBo above him who is approaching the first few days or months of life. This communication has only become abnormal if they remain too long and start to interfere with the function.

There are other examples of congenial short -circuit, such as Portosystemic Shunt (PSS). Most often it occurs in some breeds of dogs, includes a failure of normal congenital short circuit, ductus venosus, close. If this happens, it can bypass the way of sending fluids to the liver, which can cause conditions such as the inability that thrives and accumulates toxin.

In other circumstances, the shift is desirable to create a connection that did not exist or helped with the drainage of fluids. A short circuit obtained or created can treat many different types of conditions. One common type of short circuit is used to drain liquid that accumulates in areas such as the brain. If people have a timely hydrocephalus can be used by surgeons fromShort to help drain excess brain spinal cord, so swelling is reduced and the impact on the brain will be reduced. Shunt is usually associated with another tissue area that can easily withstand and absorbs liquid.

as well as congenital displacement is common in heart defects, many heart defects are repaired or pale surgical shift. Nowhere is this more common than the treatment of the conditions of one chamber, such as hypoplastic or left heart or tricuspid atresia. Surgeons use a number of palliative procedures with shifts to normalize the heart function.

Surgical procedure Glenn connects the superior vena cava with small lung veins and fontan connects Lower Vena Cava with superior vena Cava. This creates an environment in which blood returns from the body of the heart and passively flows into the lungs, reducing the workload of the heart. For certain heart defects, cardiotoracic surges can also create holes between chambers or atrials to cause displacement if one side of the heart is somehow disturbed.
