Acute Traumatic Intraparenchymal Hemorrhage: Risk Factors for Progression in the Early Post-injury Period

A large proportion of IPHs progress in the acute post-injury period. IPHs associated with subarachnoid hemorrhage, a subdural hematoma, or large initial size should be monitored carefully for progression with repeat head CT imaging. Effacement of cisterns on the initial head CT scan was strongly predictive of failure of nonoperative management, thereby leading to surgical evacuation. These findings should be important factors in the understanding and management of IPH.
