Aneurysm Wall Histology Registry

Phase 4
Completed
Conditions
Brain Aneurysm
Interventions
Procedure: Surgical Clipping of Aneurysm
Registration Number
NCT01444664
Lead Sponsor
Medical University of South Carolina
Brief Summary

The purpose of this prospective registry is to determine if patients harboring intracranial aneurysms have any predictive markers between aneurysm wall tissue, cerebrospinal fluid and blood plasma.

Detailed Description

To design a registry to evaluate the wall of intracranial aneurysms during open surgical clipping by direct photographic appearance, wall biopsy samples, CSF and blood plasma fluid collection (Interleukins; IL-8/ Matrix Metalloproteinase; MMP-9) for complete evaluation and comparison.

The focus of the registry will be to determine the presence of aneurysmal wall defects, mural clot, atherosclerotic and atheroma, wall permeability and delamination. These findings will then be correlated to the collected CSF and blood values to determine if there is any direct features of the aneurysm wall that would predict any of the reported post embolic syndromes. The collected data can also be correlated to the peroperative imaging, (MRI, CT and Angiogram).

Primary Outcome Measures
NameTimeMethod
Histological Changean average of 1 day after aneurysm treatment an analysis of the histological sample, CSF sample, and plasma samples will occur

To determine the relative and absolute differences in histological changes as seen in the tissue samples comparing this to the CSF and blood plasma samples. To also determine if there is any gene expressions that can be utilized as predictive markers in this cohort of patients.

Secondary Outcome Measures
NameTimeMethod
Treatment related morbidity and mortalityup to approximately 1 year post treatment

Secondary analyses will be performed to compare treatment related morbidity and mortality,

Clinical Outcomeapproximately clinical outcome at 6 months after surgical clipping at routine follow up visit and approximately 12 months after clipping at routine follow up visit if indicated

clinical outcome at approximately 6 months after surgical clipping at routine follow up visit and approximately 12 months after clipping at routine follow up visit if indicated

Bleeding Ratepost treatment during approximate follow up periods 6mo and 12mo clinical follow up
