Subdural Hematomas: Deadly Brain Bleeds Require Swift Action
Subdural hematomas, collections of blood between the brain's surface and skull, are serious medical conditions that can be acute or chronic. They often occur after head injuries and require prompt treatment. About 50 to 90 percent of people with acute subdural hematomas die from the condition or its complications.
Symptoms of subdural hematomas can vary and may include severe headaches, slurred speech, loss of consciousness, seizures, and permanent muscle weakness or numbness. Acute subdural hematomas are typically treated with a craniotomy, while chronic ones may be treated with a burr hole procedure. The development of microsurgery for removing subdural hematomas was a gradual evolution of neurosurgical techniques throughout the 20th century. Several neurosurgeons and researchers contributed to refining and introducing microsurgical methods, with notable figures including Harvey Cushing and Mahmut Gazi Yasargil.
Subdural hematomas can cause serious complications and require immediate medical attention. While acute subdural hematomas have a high mortality rate, about 20 to 30 percent of people can regain full or partial brain function with prompt treatment. The evolution of microsurgery has significantly improved the treatment and outcomes for patients with subdural hematomas.
