Omentum graft for intractable subdural empyema

Author and Disclosure Information


A subdural empyema developed in a young man after craniotomy for evacuation of a hematoma in a sylvian fissure arachnoid cyst and the subdural space. Despite prolonged systemic and subdural antibiotic administration and a debridement of the subdural space, infection persisted, as evidenced by persistent fever, an elevated white blood cell count, and an extremely low cerebrospinal fluid glucose level. The infection was cured after a second debridement operation where microsurgically revascularized free omentum was used to obliterate the cyst and to cover the cerebral hemisphere in the craniotomy defect. The use of vascularized free omentum may prove useful in cases of refractory cranial wound infection and cerebrospinal fluid fistulas.
