About this study
Cerebral hypoperfusion and hypoxia are the major determinants of neurological outcomes following acute brain injury as proved in Traumatic Brain Injury/Sub Arachnoid Haemhorrhage literature. How the brain injury affects cerebral oxygenation in patients with CVT is not currently known. Some of the factors that can affect cerebral oxygenation in patients with CVT are Hemoglobin, PO2, PCO2, Cerebral Perfusion Pressure (or MAP) and change in Intracranial Pressure after Decompressive Craniectomy. This study is designed to study how these factors affect cerebral oxygenation and impact of Decompressive Craniectomy on the cerebral oxygenation.

Questions about this trial
What is this clinical trial studying?
An observational study of Cerebral Venous Thrombosis, run by Dhritiman Chakrabarti at 1 site in India.
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 1 inclusion and 8 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 27 Jan 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in India. Whether a site is taking part right now should be confirmed with that site. See every site.
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?
Ipsilateral Regional Cerebral Oxygen Saturation (time frame: From Recruitment till 48 hours postoperative (end of study)). 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 27 Jan 2017; AzTrials last refreshed its copy on 8 Nov 2026.
