Biomarker-Led Optimization of Successful Surgical Outcomes in Moyamoya

Sponsor: Vanderbilt University Medical Center

Summary

The goal of this work is to use advanced magnetic resonance imaging (MRI) methods to assess brain blood flow and vascular function in adults with moyamoya disease (MMD). MMD is a condition characterized by narrowing or obstruction of major arteries in the brain and people with MMD have a high risk of stroke. Study participants will be enrolled from Vanderbilt University Medical Center and Johns Hopkins Hospital and will undergo up to two MRI scans where measurements of cerebrovascular reserve are performed using inhaled room air mixed with 5% carbon dioxide. Scans will be performed before and after surgeries to treat MMD, all surgeries are clinically indicated and are not research procedures. To further understand how surgeries impact brain health, we will also perform neurological exams and cognitive testing at approximately the same time as the imaging scans. The overall goal is to incorporate advanced imaging and cognitive assessments to understand how surgeries improve brain health in these patients, and furthermore, to use this information to develop improved screening tools for stroke risk and decisions about surgery.
