Abstract

Objective: The primary objective of this retrospective study was to evaluate the diagnostic yield and morbidity/mortality associated with frameless stereotactic neuronavigated intracranial biopsies with and without the use of fluorescein. Patients and methods: Patient cases from January 2007 to December 2017 were identified using the ICD-10 procedure code AAG00. Relevant clinical data, including histological diagnosis, were collected retrospectively from the electronic patient charts and independently reviewed by two authors. Results: 111 biopsies obtained from 103 patients were identified. Of these, 109 biopsies yielded a diagnosis and resulted in a diagnostic yield of 98.2%. Fluorescein was used in 13 biopsies (11.7%). Twelve patients (10.8%) experienced postoperative complications, and the mortality attributed to the surgery was 1.8%. In 12.6% of cases, the biopsies showed inflammation or nonspecific reactive changes. No statistically significant differences were observed in diagnostic yield or number and severity of complications according to whether intraoperative histological examination was used or not. Conclusion: Although direct comparisons between studies are difficult due to lack of consensus about the definition of diagnostic yield, the present study reports a similar diagnostic yield to other studies. Intraoperative histopathological analysis appeared to give little extra benefit.
