In traumatic brain injury, which type of hemorrhage is among the most common?

Bleeding patterns after head injury reflect where vessels are torn and how forces are applied. Subdural hematomas form from tearing of bridging veins that traverse the subdural space, making them a frequent consequence of acceleration-deceleration injuries. This type is especially common in older adults, where brain atrophy makes venous bridging veins more susceptible to injury, and it can present acutely or evolve into a chronic process. While other hemorrhages can occur in trauma—for example, arterial bleeds from skull fractures can cause layered, rapidly accumulating blood, and bleeding into the subarachnoid space from torn pial vessels can accompany diffuse injury—subdural bleeds tend to be more commonly encountered in the traumatic population overall. Intraventricular hemorrhages may appear with severe injuries but are less characteristic as a frequent pattern. Thus, subdural hematoma is among the most common hemorrhages seen after traumatic brain injury, due to the vulnerability of bridging veins to shear forces during head trauma.
