Chronic subdural haematoma treated by craniotomy, durectomy, outer membranectomy and subgaleal suction drainage. Personal experience in 39 patients

According to the CT and MRI appearances, 39 chronic subdural haematoma (CSDH) patients were suspected of having solid clots and/or a high likelihood of loculation. Craniotomy was planned from the start. Beside the better exposure, excision of the dura and outer membrane, assumed to be the source of haematoma fluid, this is an additional step to minimize the incidence of significant recollection. There were no additional operative or postoperative cranial and/or systemic complications when compared with other minor procedures. Two patients (5%) required once percutaneous tapping and aspiration. Accordingly, if a case is considered to be better managed with craniotomy, durectomy and outer membranectomy this is an easy and safe technique with minimal incidence of recollection, morbidity and mortality.
