Objective: Treatment of hydrocephalus is still a challenge to medicine. Currently, the retrograde ventriculo-sinus shunt (RVSS) is proposed in order to solve the question of ventricular catheterization complications related to siphoning. Transcranial Doppler can evaluate intracranial hypertension relief after this surgical procedure measuring brain blood flow velocities, pulsatility and resistivity index.
