MARS therapy stands for Molecular Adsorbent Recirculating System, but is often referred to as liver dialysis. Liver dialysis is done when a child has severe liver disease or poisoning that results in abnormal brain function or other problems.   

First, a soft plastic tube, called a catheter, is placed in one of your child’s large veins. Then, two machines are attached and connected to your child’s catheter. The machines pull blood through the catheter, clean it and return the blood back to your child.   

MARS therapy may help restore some brain function by removing waste products or removing poisons that have built up in your child’s body.
