The symptoms include:</p> <figure> <span class="asset-image-title">Location of the Liver</span> <img src="http://assets.aboutkidshealth.ca/akhassets/Liver_location_MED_ILL_EN.jpg" alt="" /> </figure> <ul><li>jaundice, which causes the skin to yellow</li><li>an enlarged liver</li><li>pain or tenderness in the liver, which is located on the right side of the body under the lower rib cage</li><li>gaining weight, quickly</li><li>swelling of arms, legs, and abdomen.

Your child’s doctor may also do a liver biopsy to get a better picture of the damage to your child’s liver.</p><p>To reduce the damage to the liver, your child’s health care team will balance the amount of fluid and/or perform abdominocentesis.</p><h3>Balancing the amount of fluid</h3><p>To help the liver heal, your child’s doctor carefully balances how much fluid your child intakes with how much he loses through urine. This is usually done by giving your child a limited amount of fluid to drink. At the same time, the doctor will monitor how much fluid your child loses through urine. Balancing the amount of fluid in your child ensures that we do not cause severe dehydration.</p><h3>Abdominocentesis</h3><p>In severe cases of VOD, your child’s doctor may drain any extra fluid in the abdomen. This is done through a procedure called abdominocentesis, in which doctors use a hollow needle to draw out fluid from the belly.</p>https://assets.aboutkidshealth.ca/akhassets/Liver_location_MED_ILL_EN.jpgVeno-Occlusive disease after a blood and marrow transplant
