Abstract
Stereotactic frame-based brain biopsy is one of the most used procedures to obtain brain tissue. This procedure is usually considered as mini-invasive, quick, efficient, and safe even if results of the different studies are widely heterogenous. The objective of this review of the literature is to describe and analyze the complications of stereotactic frame-based brain biopsy. About 132 articles were found after a research in the Medline database. We only considered English references published between 1994 and June 2019. Additional studies were found by using the references from articles identified in the original search. This systematic review was conducted according to PRISMA guidelines. After applying exclusion criteria, we eventually considered 25 relevant studies. The mortality rate varies from 0.7 to 4%. Overall morbidity ranges from 3 to 13%. Most of the complications are revealed by the following symptoms: neurological impairment (transient or permanent), seizure, and unconsciousness. Symptomatic hemorrhage range varies from 0.9 to 8.6%, whereas considering asymptomatic bleeding, the range may be up to 59.8%. Complications were clinically evident within minutes to a few hours after the biopsy. Corrective surgeries are very rare (< 1%). Complications occurring after a frame-based stereotactic brain biopsy are rare but with serious side effects. It rarely leads to death or to permanent neurological impairment. Description and classification of complications are often heterogeneous in the literature. The use of a grading scale could help comparisons between series from around the world. Future studies should establish a score that allows neurosurgeon to predict post-biopsy complications.Keywords
