Comparison between Papile and Volpe Grading classification of PVH-IVH.

Table 1: Comparison between Papile and Volpe Grading classification of PVH-IVH.

Papile criteria	Description	Volpe criteria	Description
Grade I	Hemorrhage limited to germinal matrix	Grade I	Blood in the germinal matrix with or without IVH less than 10% of ventricular space
Grade II	Blood noted within the ventricular system but not distending it	Grade II	IVH occupying 10–50% of ventricular space on parasagittal view
Grade III	Blood in the ventricles with distension of the ventricles	Grade III	IVH occupying greater than 50% of ventricle with or without ventricular echo-densities
Grade IV	Intraventricular hemorrhage with parenchymal extension	Separate notation of other findings	Periventricular hemorrhagic infarction
