Summary

High Resolution Imaging of Cerebral Vasculature by Functional Micro-Doppler Sonography During Brain Surgery (ULYS)

Conditions

  • Partial Drug-resistant Epilepsy

Interventions

DEVICE

Functional micro-Doppler Sonography (fmDS)

1. Craniotomy according to MRI images 2. Dura opening 3. Sulcal Localization using neuronavigation 4. Functional micro-Doppler Sonography including morphologic (Bmode) and functional measurement of the cerebral blood volume dynamics at high spatio-temporal resolution (100µm-20ms) using high-frequency (15MHz) ultrasound. At least 5 2-minute periods of spontaneous data will be recorded with a sampling rate for data acquisition of 15KHz and highpass filter of 10 to 70 Hz. 5. Exeresis of the dysplasic tissue 6. Control using fmDS before wound closure
