Trial summary

Neurosurgery for supratentorial brain tumor is frequently associated with preoperative intracranial hypertension. The evaluation of intracranial pressure is available noninvasively by measuring the diameter of the optic nerve sheath ultrasound. Read more about this study

About this study

Neurosurgery for supratentorial brain tumor is frequently associated with preoperative intracranial hypertension. The evaluation of intracranial pressure is available noninvasively by measuring the diameter of the optic nerve sheath ultrasound.

The evaluation of intracranial pressure by measuring the DNO in perioperative is not described in the literature. The investigators propose a pilot study to assess intracranial pressure perioperative surgery for supratentorial brain tumor. The investigators consider a diameter of the optic nerve sheath as normal and predictive of intracranial pressure below 20 mm Hg when less than 5.7 mm (on the average of two measurements on each eye). DNO the normal healthy adult unanesthetized is 5 mm.

The main objective of the study is to compare the mean change in diameter of the optic nerve between the postoperative and D2 between groups of patients undergoing resection of a brain tumor and patients undergoing biopsy brain tumor.

Pilot Study: Prospective, single-center, controlled, non-randomized, the number of patients is estimated according to the recruiting capabilities of neurosurgery for this type of patient in the institution, A total of 40 patients: 20 patients Tumor Resection, control group: 20 patients Biopsy Brain Tumor.

    Difference in mean changes that the sheath of postoperative optic nerve and J2 between groups of patients undergoing resection of brain tumor patients undergoing biopsy for brain tumor

    Measured: 2 days

Secondary outcomes (1)
  1. Difference in diameter of the sheath of the pre-and postoperative optic nerve

    Difference in diameter of the sheath of the pre-and postoperative optic nerve and J2 and J5 for all patients undergoing resection of brain tumor patients undergoing biopsy for brain tumor.

    Measured: 5 days

Questions about this trial

What is this clinical trial studying?

A study testing ultrasound measurement of variations in the diameter of the sheath of the optic nerve in people with Supratentorial Brain Tumor, run by Poitiers University Hospital.

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 3 inclusion and 6 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: finished, as of the sponsor's last update on 11 Oct 2016. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Difference in mean changes that the sheath of postoperative optic nerve (time frame: 2 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 11 Oct 2016.
