AIM: To present the authors? experience in treatment of chronic subdural hematoma (CSDH) by a minimally surgical percutaneous approach.

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 scan.

RESULTS: From May 2006 to December 2017, 1079 patients underwent mini-invasive percutaneous evacuation (MIPE). Of the 1079 patients, 994 (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 CSDH using our MIPE technique is a safe method with satisfactory outcome and a good therapeutic alternative to the craniostomy.
