Subdural distance is the space under the dura mater, the uppermost membrane of the brain. Subdural bleeding is called bleeding that occurs in this interval. There are three types: acute (early), subacute (early to late), chronic (late) subdural bleeding. Although it is usually the result of trauma such as traffic accidents, work accidents, falls from a height, or blows to the head, it can also occur as a result of bleeding disorders, use of blood thinners, some brain tumors, and vascular injuries. They are usually venous (vein) bleeding. The most frequently bleeding veins are the veins called bridging veins.
A neurosurgeon's opinion should be obtained for the patient who presents as a result of subdural bleeding. Your doctor will perform a complete physical examination and order some tests. These examinations include brain tomography, brain tomographic angiography, blood tests, and brain MRI. The best neurosurgeon will evaluate the results of these examinations and inform you about the stage of the subdural bleeding (acute, subacute, chronic), whether it is accompanied by any other pathology (skull fracture, brain tumor, bubble, etc.) and whether surgery is required.
While these patients may only complain of headache with all their functions normal, they may also be admitted unconscious and in a coma. Subdural bleeding is a bleeding serious enough to cause disability or death of the patient. Patients with subdural bleeding should be taken to the intensive care bed, where follow-up and treatment should be carried out.
If the size of the subdural bleeding is not large and it has not caused any impairment in the person's neurological functions, it can be followed up. But some patients undergo surgery. Subdural bleeding surgery, which is a brain surgery, is based on the principle of cutting the dura mater through the hole opened in the skull and draining the bleeding through a single hole with the help of a catheter, or by lifting the skull like a lid, as if performing brain tumor surgery, and completely opening the dura mater and draining the bleeding. Which technique will be used is decided according to the extent of bleeding, whether it is acute or chronic, and the patient's coma score.
There is dura mater in the spinal cord, as in the brain. Here too, bleeding under the dura mater, i.e. subdural bleeding, may occur. It generally develops due to trauma, tumor or vascular pathologies (such as AVM). In rare cases, herniated disc surgery horse can be seen after cervical disc herniation surgery. Treatment in the spinal cord is similar to that in the brain. In other words, if the bleeding is minor, it is follow-up, and if there is spinal cord compression, it is surgery.
