After his second operation on 05/12 Jason underwent an Emergency Surgery (likely a craniomoty or removal of part of the skull to drain the accumulating blood) due to a Subdural Hematoma which is a potentially fatal Surgical Emergency where blood pools on the brain [see image below].

Complications of a Subdural Hematoma can be as follow (from the National Institutes of Health):
  • Brain herniation (pressure on the brain severe enough to cause coma and death)
  • Persistent symptoms such as memory loss, dizziness, headache, anxiety, and difficulty concentrating
  • Seizures
  • Temporary or permanent weakness, numbness, difficulty speaking

This is definitely a DIRE situation for Jason.

Information about Subdural Hematomas can be found at the National Institutes of Health Website.
