Periventricular Leukomalacia (PVL) is a type of brain injury in premature babies. PVL is characterized by damage or decay of the white matter in the brain ventricles. This area of cell decay leaves holes in the brain that eventually fill with fluid. This white matter plays a key role in the normal transmission of electrical impulse signals within the brain. Periventricular leukomalacia is one of the leading causes of cerebral palsy and it can also cause developmental delays and epilepsy.
One of the primary causes of PVL is believed to be a reduction of blood or oxygen flow to the brain of a developing fetus during pregnancy. During early gestation, the ventricles within the brain of the baby are particularly vulnerable to developmental interruption and injury. Reduced blood, oxygen or nutrient flow from mother to baby at this time can result in damage. PVL can also be caused by maternal infections or infections of the fetal membranes (chorioamnionitis) near the time of delivery which interrupt blood and oxygen flow.
No. PVL is not a condition that will gradually get worse as a child ages so it is not considered a progressive disease. Once the damage to the white matter in the brain occurs during development it does not expand after birth. The noticeable symptoms of PVL and related conditions may become more noticeable as the child develops.
PVL CP generally refers to a case of cerebral palsy that was caused by periventricular leukomalacia. PVL is one of the leading causes of cerebral palsy.
PVL is not the same thing as cerebral palsy. Cerebral palsy is a neurological disorder that limits ability to control muscle movement and body control. Cerebral palsy is generally caused by damage to a baby's brain during pregnancy. PVL is a specific type of brain injury occurring during pregnancy. PVL is the type of brain injury that most frequently results in a cerebral palsy but they are not the same thing.
When a baby is born with PVL the condition is typically not diagnosed until months later. Symptoms of PVL are often different in each child. Some of the more common physical symptoms of PVL include:
- Developmental delays
- Trouble of with body control
- Muscle contractions or tightness (particularly in the legs)
- Vision problems and poor eye control
Some babies with PVL may also experience clinical seizures. Most of the various symptoms of PVL are also symptoms of other birth injuries or conditions.
A definitive diagnosis of PVL can be a complex process requiring a series of diagnostic brain tests. The first diagnostic tool utilized in a PVL diagnosis is a cranial ultrasound. This is basically an ultrasound (just like a pregnancy ultrasound) performed on the baby's head that provides images of the brain. A cranial ultrasound can be used to identify abnormalities in the brain caused by PVL. Additional diagnostic imaging tests, including a Computed Tomography ("CT") scan and an MRI (Magnetic Resonance Imaging), are also utilized to evaluate the extent or severity of PVL.
White matter disease is the deterioration of white matter tissue in the brain. White matter is the home for the network of nerve fibers that connect the brain to the spinal cord. The brain uses these nerve pathways through the spine to send impulse signals that control body movement. The nerve fibers are coated in a white fatty substance called myelin. White matter disease occurs when myelin breaks down and wears away which interrupts control signals from the brain.
White matter deterioration usually presents itself in older patients. Damage to white matter can be caused over time by a number of known health conditions and other factors including: chronic high blood pressure; chronic blood vessel inflammation; and smoking. Diabetes and genetic predisposition are factors that put individuals at increased risk of white matter damage.
There currently is no known cure for white matter disease. Once white matter is damaged it cannot be restored or reversed.
There is no effective treatment that will restore white matter. Instead treatment of white matter disease focuses on slow down or stopping the condition from getting worse. This will involve treatment of the underlying conditions that are causing the white matter to decay - such as hidh blood pressure or cholesterol.
Unfortunately, there is no known treatment for PVL. The damaged and decayed white matter in the brain can never be restored. PVL is a permanent condition, however, effective management and careful monitoring can help limit the impact of PVL. Physical and occupational therapy can also be used to help deal with PVL.
Like all birth injuries, PVL can often be the result of negligent medical care during pregnancy or delivery. PVL is known to be caused by a loss of blood or oxygen flow to a baby's brain during pregnancy. There are a number of conditions and complications during pregnancy that can interrupt or restrict blood and oxygen flow. Doctors have a legal obligation to properly monitor a pregnant mother and timely diagnose these conditions when they arise. They also have a duty to effectively treat and manage these conditions in accordance with acceptance medical practices. The reality is that OBGYNs and hospital delivery teams often make mistakes. Complications such as maternal infections or fetus infections (chorioamnionitis) frequently go undetected. Delayed responses and mistakes in treatment occur just as frequently. These sort of medical errors can result from a variety of factors including poor communication between doctors; improper testing or monitoring, etc.
When negligent care results in birth injuries such as PVL the financial, emotional and physical impact can be devastating. PVL is a permanent condition that can result in cerebral palsy and other serious developmental conditions. Aside from the obvious physical impairments, these conditions can cause a lifetime of financial hardship. This is why our legal system enables victims of medical malpractice to obtain financial compensation.Sample Verdicts & Settlements
- M.A. Pro Ami v. St. Joseph Med. Center (2015 Maryland) - $2 million Verdict: In this case baby was born prematurely via c-section and was later diagnosed with PVL and cerebral palsy. Plaintiff alleged that doctor was negligent in failing to monitor and recognize certain complications and in delivering baby too early.
- Zaya v. Rush Health System (2015 Illinois) - $1.5 million Settlement: Plaintiff alleged that her doctors were negligent in failing to timely treat her chorioamnionitis infection with antibiotics. As a result of the untreated infection her baby was born with PVL and had permanent vision loss and developmental delays.
- Smith v. Lee Memorial Health System (2015 Florida) - $19 million Verdict: Hospital and doctors in this case were negligent in failing to diagnose a maternal infection during pregnancy and in administering an overdose of drugs in response. Baby born with PVL as a result leaving her confined to a wheelchair.
