What Causes Fluid on the Brain in Babies
What is Hydrocephalus?
Hydrocephalus is a buildup of fluid in the encephalon, or more than precisely, cerebrospinal fluid in the ventricular system, which causes potentially damaging increased pressure level in the caput. Most children who have information technology are born with information technology. It occurs in one or two per i,000 live births.
The ventricular organization in the brain is fabricated upwardly of four chambers that concord most of the cerebrospinal fluid that is in the head. The ii upper chambers are called the left and right lateral ventricles. They connect to the tertiary chamber or ventricle, which drains into the fourth.
Cerebrospinal fluid is a water-similar substance that acts to absorber the brain within the skull. Information technology also filters waste from tissue in and around the brain.
The cerebrospinal fluid is made in the walls of the ventricles. The fluid flows from the upper ventricles downwards to the lower ventricles and and then over the surface of the brain and around the spinal string. The cerebrospinal fluid is captivated over the surface of the brain into the bloodstream.
Cause of Hydrocephalus
Hydrocephalus (left) and normal brain (right).
Hydrocephalus occurs when the body makes more than cerebrospinal fluid than the encephalon absorbs. A child may be born with this, merely it can happen to a person at any age. Older children or adults with an abnormal growth in the head (tumor) or a head injury can develop hydrocephalus.
Hydrocephalus has ii base causes: the bloodstream is not fully absorbing the fluid due to a damaged filter in the brain and / or the flow of fluid within the ventricles is blocked.
Any significant block in the ventricular system will cause hydrocephalus since cerebrospinal fluid is made in that location. This blockage can occur due to a buildup of droppings that blocks the flow of fluid or can be from a smaller than normal opening in the ventricular system.
This narrow opening in the ventricular system may happen during the baby'due south growth in the womb. The debris which collects and creates a blockage tin be from an infection or from haemorrhage (hemorrhage) after birth. A tumor in the caput may also block the flow of cerebrospinal fluid.
This buildup of fluid causes increased pressure in the caput. If untreated, over time it tin can cause harm to the brain.
Signs and Symptoms of Hydrocephalus
- Your infant'southward doc may order a screening for hydrocephalus if your babe'south head is growing more apace than others his age.
- Headaches and airsickness are signs of increased intracranial force per unit area, which can event from hydrocephalus.
Handling for Hydrocephalus
The near common treatment for hydro is inserting a ventricular shunt. A shunt is a tube that drains the CSF from the ventricles to some other space in the torso, which so absorbs the fluid.
A 2nd type of treatment for hydrocephalus is endoscopic 3rd ventriculostomy (ETV). This procedure has proven more effective at managing hydrocephalus caused by the ventricular system. It is not used for children who have a damaged filter in the brain that does not allow cerebrospinal fluid absorption into the bloodstream.
Preparing for Surgery
Whether your child is getting a shunt or is having endoscopic tertiary ventriculostomy, to assistance us prepare for a successful surgery, delight share with u.s.a. your child's full medical history.
During the Surgery
Prior to surgery, your child's surgeon will choose the most appropriate surgery, either the shunt or endoscopic tertiary ventriculostomy. The neurosurgeon will discuss the process in detail with you lot earlier your child'due south scheduled surgery appointment, but hither is a brief description.
Shunt − The offset step in the shunting procedure is placing a ventricular catheter through the skull into the ventricular system. A ventricular catheter is a tube with tiny holes. This catheter is continued to a pressure valve that serves to regulate the amount of spinal fluid drainage.
Another long, thin tube called a distal catheter is attached to the valve. This is the tube that drains the cerebral spinal fluid. The distal catheter and valve are located underneath your child'southward skin.
Endoscopic Third Ventriculostomy (ETV) − For this procedure, the surgeon makes a small hole in the bottom of the third ventricle so that cognitive spinal fluid bypasses the obstacle and flows into the natural pathways.
Both of these surgeries are performed under general anesthesia and will exist scheduled for at to the lowest degree 1 hour and a half.
After Surgery
Your child will become to the Post Anesthesia Intendance Unit (PACU) after surgery, and the surgeon will update you lot on how well the surgery went. When you get a phone call from the PACU, you may bring together your child.
Your kid will spend one to three nights with united states, and we will take care of special dietary needs (general anesthesia may cause an upset stomach). Your child may go home when he or she:
- Is eating and drinking well
- Is walking effectually without problems
- Is keeping pain under command
- Has had a bowel motility
Before you exit, make sure to schedule a follow-upwards engagement to run into the pediatric neurosurgeon nigh 14 days after surgery.
Caring for Your Child at Home
Here is some basic information to help you care for your child at home after surgery.
Pain − If your child is nether 4 years of age, give regular children's Tylenol as directed for his or her pain. Children older than 4 years may exist sent home with a prescription for Tylenol with Codeine.
Diet − Once your child is domicile, he or she volition be on a regular diet. There are some restrictions right afterwards surgery, simply since your child will be spending several nights with us, we will restrict the nutrition as needed during that fourth dimension.
Wound care − Wash your child's incision each mean solar day with a mild shampoo.
Activeness − Your kid may slowly resume regular activities. Your child may return to schoolhouse or daycare iii to 5 days later surgery, depending on how he or she feels.
Medication − No medicines are given routinely after hydrocephalus surgery. If your child complains of pain at the site of the incision, give him or her Tylenol.
Bathing – Wash the wound daily with a mild soap or shampoo and rinse with clear water. A shower is fine if your child typically takes showers. Do not let the wound soak in water such as a bathtub or pond pool until the pare is completely healed.
Follow-upwardly care − Almost 14 days later surgery, your kid volition have a follow-upwardly appointment with the Neurosurgery Segmentation for a wound check. During that visit, nosotros may also take more images of your child's brain. If your child becomes ill in the future, this will help us figure out if hydrocephalus is causing the problem.
Watch your child for whatever signs of hydrocephalus. These would typically be the same symptoms that prompted the surgery. (Encounter Shunt Malfunction for signs of hydrocephalus.)
