Objectives: Stereotactic
biopsy (SB) is a guided technic performed for the lesions on eloquent brain
areas. The aim of this study is revealing the diagnostic reliability and the
risk ratio of SB.
Methods:
Data of patients performed SB due to various intracranial lesions was collected
retrospectively. The study took place in Department of Neurosurgery, Gazi
University Faculty of Medicine between February 2004 and April 2014. Data
analysis performed in terms of age, gender, lesion location, histopathology,
and outcomes of surgery.
Results:
Sixty percent of patients were male (146 patients) and forty percent of them
was female (96 patients), between the ages of 11 and 84 years (mean age of 49
years) with a total number of 242. Mortality and morbidity rates were
respectively 0.4% and 3.3%. The overall diagnostic yield was 81% (196
patients), while 19% (46 patients) had nonspecific results, which did cannot
lead any further therapy. Among 36 patients of whom pathologies were confirmed
with an excisional biopsy, the diagnostic accuracy was shown in 24 patients
(67%).
Conclusions:
Beside low risk of mortality and morbidity, the high rate of non-diagnostic
results and low rate of diagnostic accuracy are the limitations of SB, which
should be improved by careful skills to obtain more specimen, sophisticated
software for planning, and intraoperative pathological examination for
guaranteeing.
