A SDH is usually venous in origin and is often self-limiting by the rising intracranial pressure.A SDH of significant size can disrupt the physiologic flow of cerebrospinal fluid and consequently raise the intracranial pressure [1,2].To learn more about this study, you or your doctor may contact the study research staff using the contact information provided by the sponsor.A total of 24 RCTs involved 1900 patients and 15 comparisons. Postoperative drainage after burr-hole evacuation reduced the rate of recurrence (risk ratio 0.48, 95% confidence interval 0.34−0.66, This comprehensive, best evidence−based, quantitative, systematic review indicates that the use of a closed system drainage after burr-hole evacuation reduces the rate of recurrences but has no other significant differences.However, new evidence suggests that a chronic SDH enlarges because of recurrent spontaneous bleeding from a richly vascularized membrane encapsulating the hematoma.

A SDH forms between the dura and the arachnoid membranes, when the bridging veins draining blood from the surface of the brain to the dural sinuses rupture spontaneously or by shearing forces in head trauma [2].There is currently no agreement among physicians as to the best way to treat this condition.One option is to do a surgery to drain the blood that has collected.The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Know the risks and potential benefits of clinical studies and talk to your health care provider before participating. Chronic subdural hematoma (c SDH) is condition where blood has slowly leaked out of small blood vessels surrounding the brain.Listing a study does not mean it has been evaluated by the U. Over time, the blood may cause a variety of symptoms including headache, confusion, limb weakness, and difficulty speaking.
