A chronic SDH is an “old” blood collection and a blood breakdown between the brain’s surface and its periphery (the dura). After a first bloating a few weeks, the recurrent stage of a subdural hematoma begins.

An SDH arises as tears and spills blood from the small veins flowing between the dura and the brain surface (bridging veins). Typically this is caused by a minor head injury. The surface of the brain is then collected in blood. Blood spills steadily from the veins in a chronic subdural collection over time, or a quick hemorrhage is left behind. The typical brain shrinking happens with increasing age, and subdural hematoma is more frequent in the elderly. This decline spreads out the bridging veins and weakens them. Even after mild head trauma, these veins are more likely to burst in the elderly.


The procedure is normally conducted under local anesthesia and is typically well-tolerated. Around 45 degrees from the hematoma side the head of the patient is twisted and secured to a headrest of a horseshoe with tape. In the region above the full thickness of the hematoma, a burr hole is created. In the case of a large holohemispheric cortex, the burr hole is placed on the coronal suture in order to prevent possible damage to the engine cortex. One drain is reached in the direction of the dorsal at the lowest point of the cavern, and the other at the highest point frontally. The exact distance from the burr hole to the highest point and the deepest point is determined with the CT scan and labeled on each drain.

Treatment at B.P Poddar:

The B.P Hospital in Podder, Kolkata, India has advanced and new technologies to eradicate brain-blood pooling or subdural hematoma (SDH) for the purpose of subdural evacuation. Advanced technology congratulates our team of neurosurgery on their challenging and inexpensive expense of performing neurosurgery. Subdural hematoma (SDH) Surgery is among the lowest in comparison to other centers in Kolkata, India at the B.P Poddar Hospital.

The purpose of therapy is to monitor and avoid symptoms and irreversible brain injury. The operation could be required. This will involve boiling small holes to alleviate pressure and allow drainage of blood and fluids. A bigger opening in the skull (craniotomy) may be required for removing large hematomas or strong blood coagulation. No medication may be required for hematomas that do not cause symptoms.
