Enlarged Craniotomy with Membranectomy for Treatment of Completely Organized Chronic Subdural Hematoma: A Case Report and Literature Review

Abstract

<jats:title>Abstract</jats:title> <jats:p><jats:bold>Background </jats:bold>Chronic subdural hematoma(CSDH) is a common condition in the elderly which can be treated by burr hole trephination and drainage. But completely organized chronic subdural hematoma(OCSH) is rare which cannot be cured by this technique, only treated by enlarged craniotomy and membranectomy.<jats:bold>Case Presentation </jats:bold>A 74-year old man admitted to hospital for loss of consciousness for one hour following a car accident. Cranial computed tomography (CT) showed a large mixed density hematoma on the left, acute subdural hematoma, cerebral contusion and subarachnoid hemorrhage. A left standard large craniotomy was performed. A large and completely OCSH with no liquid component was found during surgery, at the same time, we found no obvious adhesions between the inner membrane and the brain tissue, which was easy to separate and finally removed completely. <jats:bold>Conclusion </jats:bold>Craniotomy with membranectomy is a feasible method for treating completely OCSH.</jats:p>
