• Definition of posthemorrhagic hydrocephalus
Posthemorrhagic Hydrocephalus (PHH) is a neurological disorder that occurs when spinal fluid accumulates in the brain, causing the ventricles or cerebral cavities to expand. PHH is typically seen in premature infants who have suffered an intracerebral hemorrhage or blood clot in the brain. Additionally, PHH can develop in adults as a result of a traumatic brain injury or a stroke that affects the brain’s blood supply. Symptoms of PHH can include headaches, balance issues, irritability, seizures, nausea, depression, and language and learning problems. In severe cases, PHH can cause hydrocephalus ex-vacuo, which occurs when fluid accumulates in the brain in the absence of any other underlying condition. Treatment for PHH typically involves a combination of medications, surgery, and physical or occupational therapy to improve balance and coordination.
• Causes
Posthemorrhagic hydrocephalus is a potentially life-threatening accumulation of cerebrospinal fluid (CSF) in the brain. The primary cause of this disorder is bleeding in the brain from a traumatic injury or infection. The following are the main causes of posthemorrhagic hydrocephalus:
- Severe head injuries
- Brain infections, such as meningitis or encephalitis
- Complications of premature birth
- Intracranial hemorrhage
- Neoplasms (abnormal tissue growth)
- Aneurysms or arteriovenous malformations
Though the exact cause of most posthemorrhagic hydrocephalus cases is unknown, it is important to identify and treat the underlying cause promptly to reduce the risk of complications. When the underlying condition can be successfully managed, posthemorrhagic hydrocephalus can be successfully treated in most cases.
• Symptoms
Posthemorrhagic hydrocephalus is a serious medical condition that affects newborn babies. It is caused by an abnormal accumulation of cerebrospinal fluid (CSF) in the brain. The most common symptom of posthemorrhagic hydrocephalus is an abnormally large head size due to increased pressure in the skull. Other symptoms include bulging fontanelles (soft spots) on the baby’s head, bulging eyes, irritability, seizures, vomiting, difficulty feeding, tiredness, and difficulty with coordination. In some cases, babies may also have delayed development of physical or cognitive skills. It is important to seek medical attention if any of these symptoms are present in an infant so that a diagnosis can be made and appropriate treatment can begin.
• Diagnosis
Posthemorrhagic hydrocephalus (PHH) is a serious health condition that develops when excessive cerebrospinal fluid accumulates in the ventricles of the brain, leading to a swelling of the head and other symptoms. Diagnosing PHH can be difficult and usually involves a combination of tests, including medical history, physical examination, and imaging or laboratory tests. A thorough medical exam by a qualified healthcare provider is the best way to diagnose PHH and rule out other possible causes of symptoms, such as infection, normal pressure hydrocephalus, and traumatic brain injury. Imaging tests, including CT scans and MRI scans help doctors to get an in-depth look at the patient’s brain and can help to identify any swelling of the ventricles, which would be indicative of PHH. In some cases, a doctor may also choose to perform a lumbar puncture, which involves drawing a sample of the fluid to measure its pressure and composition. With a combination of these tests, doctors can accurately diagnose PHH and start treatment right away.
• Treatment
Posthemorrhagic Hydrocephalus is a condition defined by accumulating fluid pressure in the skull, leading to increased intracranial pressure. This is a serious, potentially life-threatening condition. Treatment of this condition includes both surgical and non-surgical options:
- Surgical treatment options include:
- Ventriculoperitoneal shunt: designed to allow the excess fluid to drain and be absorbed
- Endoscopic third ventriculostomy: involves cutting of a hole in the floor of the third ventricle
- Craniotomy: involves drilling of a hole in the skull for the purpose of removing fluid
- Non-surgical treatment options include:
- Medication: Steroids, diuretics, and other drugs may be used to reduce swelling and facilitate the flow of cerebrospinal fluid
- Physical therapy: Helping the patient to strengthen their physical conditioning and restore their body to as normal a state as possible
- Counseling: Supportive and psychotherapy services to help patients cope with the physical and emotional impact of the condition
The goal of treatment is to reduce the pressure of the fluid in the ventricles, reduce the hydrocephalus symptoms, and restore the patient’s neurological and cognitive abilities. Because the condition is severe, it is important to seek medical attention from a professional if hydrocephalus is suspected.
• Prevention and Outlook
Posthemorrhagic hydrocephalus is a serious neurological condition that requires prompt diagnosis and treatment. Prevention is key in reducing the risk of this condition. The outlook for posthemorrhagic hydrocephalus depends on the underlying cause and the damage caused to the brain. Early diagnosis and treatment can help improve the prognosis.Here is a list of prevention tips:
- Reduce your risk of trauma to the head by using safety gear when participating in contact sports.
- Avoid falls by using safety equipment when climbing or doing activities that require balance.
- Wear protective headgear when riding motorized vehicles or bicycles.
- Seek prompt medical attention for any head injury.
- Maintain a healthy diet and exercise routine to reduce the risk of stroke and other vascular events.
Early diagnosis and care can help increase the chances of a successful outcome. With prompt treatment, the outlook for posthemorrhagic hydrocephalus can be improved. In some cases, the symptoms may resolve completely, while in other cases there may be some lingering effects. Regular follow-up with your doctor is important to monitor for any signs of progression of the condition.
