Hydrocephalus due to congenital stenosis of the aqueduct of Sylvius is a pathological condition characterized by an increase in the volume of cerebrospinal fluid in the ventricles of the brain as a result of a disruption of its normal outflow due to stenosis (narrowing) of the aqueduct of Sylvius. This condition can lead to increased intracranial pressure, which can lead to serious neurological consequences. It is important to note that the disease can manifest itself both in the neonatal period and at a later age, depending on the nature of the stenosis and the adaptive mechanisms of the body. Clinical manifestations can vary from mild cognitive impairment to severe forms of cerebral dysfunction.
History of the disease and interesting historical facts
The first mention of hydrocephalus is found in the works of the ancient Greek physician Hippocrates, who described symptoms comparable to this disease. However, a modern understanding of the disease became possible only with the development of neurology and neurosurgery in the 19th century. In 1914, K. M. Kalman was the first to propose a method of cervical-spinal drainage, which provided a new approach to the treatment of hydrocephalus. Historically, there are many cases of mysterious "dead" children, which, as it turns out, are often explained by congenital hydrocephalus. The study of diseases associated with glands and X-ray diagnostics played a key role in understanding the pathogenesis and mechanisms affecting the development of this condition.
Epidemiology
Epidemiological statistics of hydrocephalus indicate that the disease occurs in 0.2-0.4% newborns. According to the World Health Organization, congenital stenosis of the aqueduct of Sylvius accounts for about 60% of all cases of hypertensive hydrocephalus. The incidence rate is especially high among children with other associated developmental anomalies, such as spinal dysraphia. The disease is also more common in males, with a ratio of 2:1 compared to females. At the same time, not all cases provide obvious signs, which makes it difficult to estimate the real number of sufferers.
Genetic predisposition to this disease
Molecular studies have shown that genetic predisposition to hydrocephalus may be associated with various mutations, especially those in genes involved in the development of the nervous system. The most commonly involved are the L1CAM gene, located on chromosome X, and mutations in the ARX and HESX1 genes. It is important to note that in families with a history of developmental defects, the likelihood of hydrocephalus in newborns may increase. The associated genetic predisposition factors indicate the need for genetic counseling for parents, especially during pregnancy planning.
Risk factors for the development of this disease
Physical and chemical risk factors for the development of hydrocephalus are:
- Infections during pregnancy, including rubella and cytomegalovirus.
- Teratogens such as alcohol and some medications.
- Maternal folate deficiency.
Other possible risk factors include:
- Presence of cases of critical developmental anomalies in the family.
- Viral diseases, maternal suffering in the first trimester.
- Autoimmune diseases in pregnant women.
Diagnosis of this disease
The main symptoms of hydrocephalus may include:
- Increase in head circumference in children.
- Symptoms of swelling or pressure on the optic nerves.
- Delayed mental and physical development.
Laboratory tests may include tests for infectious and genetic factors. Radiological tests, such as ultrasound or MRI, are key to assessing the brain's water spaces and confirming the diagnosis. The differential diagnosis must include ruling out other types of hydrocephalus, such as acquired hydrocephalus.
Treatment
Treatment of hydrocephalus due to congenital stenosis of the aqueduct of Sylvius includes both medical and surgical interventions. General treatment is focused on symptom control and reduction of intracranial pressure. Pharmacological treatment may include the use of diuretics to reduce symptoms. The main method of surgical intervention is the installation of a shunt to normalize the outflow of cerebrospinal fluid. Postoperative care and rehabilitation of patients require special attention.
List of medications used to treat this disease
Some of the main medications used to treat hydrocephalus are:
- Acetazolamide
- Furosemide
- Potassium-containing drugs
- Drugs for control of adequate intracranial pressure level
Disease monitoring
Control stages of monitoring include regular neuroimaging examinations and clinical examinations to assess the dynamics of development. The prognosis of the disease may vary depending on the timeliness of diagnosis and surgical intervention. Possible complications may include shunt system infections, recurrent hydrocephalus and neurological abnormalities. Densauls of newborns before and after surgery require special attention and correction of the necessary disorders.
Age-related features of the disease
The impact of hydrocephalus may vary in different age groups. In newborns, the disease often manifests itself as a clearly visible enlargement of the head and examinations related to the study of the brain and cerebrospinal fluid. In older children, mental and physical development may be delayed, and in adolescence, there is a high risk of neurological disorders if not properly treated.

Advice from Dr. Oleg Korzhikov
Doctor Oleg Korzhikov advises parents to be attentive to signs of increased intracranial pressure and to contact specialists immediately. "Always remember that early diagnosis and treatment play a key role in forming the prognosis of treatment. Follow all recommendations of doctors and do not neglect regular check-ups," he notes.
