Haemorrhagic complications and the incidence of asymptomatic bleeding associated with stereotactic brain biopsies

Object. Stereotactic brain biopsy is a routinely used technique for the diagnosis of brain lesions. Due to its minimally invasive nature, the potential risks associated with this procedure are sometimes underestimated. We have retrospectively analyzed the incidence of symptomatic and asymptomatic haemorrhagic complications associated with stereotactic biopsies. Various variables that may contribute to such complications have been retrospectively analyzed.
