Obstructive hydrocephalus
What is Obstructive hydrocephalus?
Obstructive hydrocephalus (also called non-communicating hydrocephalus) is a form of hydrocephalus which is caused by some visible blockage in the flow of cerebrospinal fluid.
Hydrocephalus is a condition caused by abnormal flow and/or re-absorption of the cerebrospinal fluid, the water-like liquid that surrounds the brain and spinal cord and fills the open spaces within the brain, the ventricles. This can lead to increased pressure inside the head which then can lead to dysfunction and/or damage to the nervous system. In most forms of hydrocephalus, the ventricles inside the brain enlarge as the pressure increases.
Hydrocephalus can be caused by a visible (on brain scans) obstruction of the normal flow this fluid. This cause is called obstructive hydrocephalus because it is caused by obstruction of this flow of fluid. Another name for this type of hydrocephalus is non-communicating hydrocephalus. Most commonly, obstructive hydrocephalus is caused either by a mass in the brain which blocks the flow of fluid, such as a brain tumor, or some scarring or malformation which narrows or completely blocks part of the flow of fluid. These are often termed rings or webs. They can occur either due to some prior trauma, bleeding or infection, or can be congenital, present at birth. In some cases they can be idiopathic, meaning that they have no known medical cause.
One of the most common sites in the brain for obstruction is the cerebral aqueduct. This area is a narrowing of the ventricles within the brain and therefore is prone to obstruction. Either rings, webs or tumors in the area can cause obstruction of the aqueduct, termed aqueductal stenosis.

Congenital aqueductal stenosis has an estimated incidence of ~1:5000 births although the reported range varies greatly.

Clinical Trials
CoRDS, or the Coordination of Rare Diseases at Sanford, is based at Sanford Research in Sioux Falls, South Dakota. It provides researchers with a centralized, international patient registry for all rare diseases. This program allows patients and researchers to connect as easily as possible to help advance treatments and cures for rare diseases. The CoRDS team works with patient advocacy groups, individuals and researchers to help in the advancement of research in over 7,000 rare diseases. The registry is free for patients to enroll and researchers to access.
Enrolling is easy.
- Complete the screening form.
- Review the informed consent.
- Answer the permission and data sharing questions.
After these steps, the enrollment process is complete. All other questions are voluntary. However, these questions are important to patients and their families to create awareness as well as to researchers to study rare diseases. This is why we ask our participants to update their information annually or anytime changes to their information occur.
Researchers can contact CoRDS to determine if the registry contains participants with the rare disease they are researching. If the researcher determines there is a sufficient number of participants or data on the rare disease of interest within the registry, the researcher can apply for access. Upon approval from the CoRDS Scientific Advisory Board, CoRDS staff will reach out to participants on behalf of the researcher. It is then up to the participant to determine if they would like to join the study.
