Final answer:
A subdural hematoma is a type of intracranial bleeding outside the brain tissue that can result from head injuries, potentially causing increased pressure on the brain and life-threatening symptoms. It requires immediate medical attention and can be diagnosed with imaging techniques like CT scans.
Step-by-step explanation:
What is a Subdural Hematoma?
A subdural hematoma is a type of bleeding that occurs inside the skull but outside the brain tissue itself. It usually results from a head injury that causes blood to collect between the dura mater (the tough outer layer of the meninges that envelop the brain and spinal cord) and the arachnoid mater (the delicate membrane under the dura mater).
A subdural hematoma can increase pressure on the brain and can be life-threatening. The pterion, located on the lateral side of the skull, is a region where a blow can lead to bone fracture and damage to the major arteries beneath, which can cause a hematoma.
Symptoms and Signs (S/S) of a Subdural Hematoma
The symptoms associated with a subdural hematoma may not be immediately apparent. Over time, as blood accumulates, symptoms can include headache, drowsiness, confusion, loss of consciousness, or even death.
Hemorrhagic strokes are an example of what can happen when blood accumulates in the cranial vault, causing pressure on the brain and potential damage.
Importance of Prompt Medical Attention
It is essential to seek prompt medical attention if a person suffers a head injury or exhibits symptoms of a subdural hematoma. Advanced imaging techniques such as CT scans are used for diagnosis.
If untreated, the increasing pressure on the brain can cause severe and lasting damage or death. The superior sagittal sinus, an important venous channel inside the skull, often drains the blood from these types of injuries.
