RESUMEN
Objective: Frameless stereotactic biopsy has been shown in multiple studies to be a safe and effective procedure for the diagnosis of brain lesion. In this study the authors will evaluate the safety of the procedure and associated complications including neurological deficits in our set up of developing countries
Methods: Forty two patients with different brain lesions were biopsied using frameless stereotactic procedure between the periods of March 2009 - March 2014 for the assessment of diagnostic yield and related complications
Results: During the study period, forty two patients were biopsied for the evaluation of the complications related to the biopsy site. Neurological decline occurred in 1 patient. A higher number of needle passes was associated the presence of a postoperative hematoma. Infection occurred in one patient and overall diagnostic yield was 95%
Conclusion: Frameless stereotactic biopsy is a safe and effective method of tissue diagnosis for small lesions located in the eloquent and non-eloquent region of brain. With careful planning, frameless biopsy remains a valuable and safer tool for diagnosis of brain lesion, independent of the location of these lesions
