Medical Context Simplified
An epidural hematoma occurs when blood collects between the skull and the dura mater, often due to arterial bleeding. Rapid neurosurgical intervention can improve outcomes, but delays or rebleeding increase mortality risk. In the episode, delays in imaging and transfer, followed by a second bleed, lead to irreversible brain injury despite surgical efforts.
Immediate Aftermath in the Series
Following Derek's death, the show addresses the impact on Meredith Grey, their children, and the broader surgical team. Episodes after April 2015 focus on grief, legal consequences, and changes in hospital dynamics. Cristina Yang's departure later in Season 11 is partly framed as a ripple effect of the trauma and loss experienced by the team.

Derek's death remains a defining event in Grey's Anatomy, influencing storylines and character decisions in Seasons 12 through 19.
