Aim: Chronic subdural hematoma(CSDH) is a commonly encountered entity in neurosurgery in particular in elderly patients. It likely to occurs over 65 years of age. Bleeding may be spontaneous or caused by benign or minimal head trauma that often goes unnoticed. Types of presentation of CSDH are extremely variable, so that we can call it “the great imitator”! There is a high variance in the treatment in literature but at any rate, surgery is still the primary therapy.Material and Methods:We relate our experience of mini-invasive evacuation of chronic subdural hematoma. Between May 2006 and December 2017, 1079 patients have been operated for percutaneous evacuation of chronic subdural hematoma. Prior to operation, the volume of hematoma was measured quantitatively by using a software for CT scanResults:From May 2006 to December 2017, 1079 patients underwent mini-invasive percutaneous evacuation(MIPE). 994 of the 1079 patients (92.12%) became asymptomatic or improved clinically. Six weeks later, the scan revealed the hematoma had wholly disappeared in 699 (64.78%) of the cases. We had one postoperative abscess. Conclusion:Treatment of chronic subdural hematoma using our mini-invasive technique (MIPE) is a safe method with satisfactory outcome and a good therapeutic alternative to the craniostomy.
