Subdural hematomas grow continually larger as a result of the pressure they place on the brain: As intracranial pressure rises, blood is squeezed into the dural venous sinuses, raising the dural venous pressure and resulting in more bleeding from the ruptured bridging veins. They stop growing only when the pressure of the hematoma equalizes ...
Subdural hemorrhage (SDH) results from tearing of the bridging veins in the subdural space between the dura and arachnoid mater. It can cross the suture lines, but not across dural reflections such as falx cerebri or tentorium cerebelli. [4] Therefore, subdural hematoma always limited to one side of the brain. [3]
The American Heart Association and American Stroke Association guidelines in 2015 recommended decreasing the blood pressure to a SBP of 140 mmHg. [1] However, later reviews found unclear difference between intensive and less intensive blood pressure control. [38] [39] Giving Factor VIIa within 4 hours limits the bleeding and formation of a ...

Most cases of primary intraparenchymal hemorrhage are the result of chronic hypertension (high blood pressure), cerebral amyloid angiopathy, or both. While these are the causative processes for most cases, a number of other pathological processes are known to accelerate or worsen them, including coagulopathy , vasculitis , brain tumors ...
Epidural hematoma involves bleeding into the area between the skull and the dura mater, the outermost of the three membranes surrounding the brain. [11] In subdural hematoma, bleeding occurs between the dura and the arachnoid mater. [23] Subarachnoid hemorrhage involves bleeding into the space between the arachnoid membrane and the pia mater. [23]
Cerebral edema is commonly seen in a variety of brain injuries including ischemic stroke, subarachnoid hemorrhage, traumatic brain injury, subdural, epidural, or intracerebral hematoma, hydrocephalus, brain cancer, brain infections, low blood sodium levels, high altitude, and acute liver failure.
A subdural hygroma (SDG) is a collection of cerebrospinal fluid (CSF), without blood, located under the dural membrane of the brain. Most subdural hygromas are believed to be derived from chronic subdural hematomas. They are commonly seen in elderly people after minor trauma, but can also be seen in children following infection or trauma.
