Acute subdural hematoma / PGS / diagnostics

This is the most common type of traumatic intracranial hemorrhage, it occurs even after a negligible, often almost unobserved injury. The accumulation of blood is between the dura mater and the arachnoid (see picture), as a result of the rupture of the bridging veins, or vial vessels. The most common localization is in the frontal and parietal area, often (15–20%) bilaterally. The classic course is characterized by the development of focal symptoms (from direct hematoma pressure or from herniation) and alterations in consciousness. Unlike AEDH, the development of symptoms tends to be slower, within hours of the accident. It has a semilunar shape on the CT image. The elderly and patients with increased bleeding are particularly at risk of developing ASDH.
