About this study

To evaluate accuracy of (MRI) cerebrospinal fluid flowmetry after shunt operation in patients with borderline (grey zone) hydrocephalus.

Read the detailed description

Hydrocephalus could be defined as disturbance of formation, flow or absorption of CSF. We encounter some challenging cases with intermittent non specific symptoms as delayed milestones and headache with concomitant imaging showing dilated ventricular system, so we find ourselves hesitating to take the decision of surgical intervention to put shunt or not, therefore MRI CSF flowmetry gives us a chance to overcome this problem. Phase contrast MR imaging is a rapid, simple and non-invasive technique which is sensitive to even small CSF flows, and can be used to evaluate CSF flow both qualitatively and quantitatively.

CSF flow measurement at the suspected level of obstruction gives reliable and reproducible results for more accurate diagnosis and can be used to guide therapeutic decisions in a more reliable manner, and follow up post treatment outcome.

With the CT and magnetic resonance imaging (MRI) techniques, it is possible to localize with accuracy the exact site of blockage of flow to CSF. Hence classification is as follows: The hydrocephalus may be due to 1) overproduction of CSF 2) obstructive 3) absorption defect. Depending on the exact aetiology, a secondary classification could be added under the following headings: 1) congenital, 2) acquired, eg; traumatic inflammatory, neoplastic, and degenerative . Bypassing the site of obstruction to CSF flow by diverting the CSF from ventricular cavity to a site where it is readily absorbed is the basic principle underlying the treatment of hydrocephalus. Extensive range of complications has been reported for shunting for hydrocephalus. They could be classified as mechanical or flow-related complications as CSF over drainage leading to subdural hematoma, subdural collections, low-pressure headaches cranial deformity, and asymmetrical drainage can lead to trapping or isolation of a part of a ventricular system. The slit ventricular syndrome is a complication related to absorption. Besides, ascites, loculations, hydrocele, perforation of the stomach, large and small bowel are also described. The success rates of shunt operation for hydrocephalus depend on the age of the patient and the reason why the shunt is needed. Generally, there is around a 50% failure rate for ventriculoperitoneal shunts.

Questions about this trial

What is this clinical trial studying?

A study testing MR CSF flowmetry in people with Hydrocephalus, run by Assiut University.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 19 Aug 2019. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Mohammad Mohammad (01005663647, mohamed011353@med.aun.edu.eg), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Decompressive changes in CT brain (time frame: 2 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04060810, which also lists 5 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Aug 2019.
