biopsy-only procedure
A neurosurgical approach where only tissue sampling is performed without attempt at tumor resection, typically for deep or eloquent location lesions.
Full Definition
A biopsy-only procedure is a minimally invasive neurosurgical technique used when complete or partial tumor resection is not feasible due to tumor location, patient condition, or other factors. This approach involves obtaining tissue samples for histopathological diagnosis while avoiding the risks associated with more extensive surgery. It is commonly employed for deep-seated tumors, lesions in eloquent brain areas, or when the primary goal is establishing a diagnosis rather than cytoreduction. The procedure can be performed using stereotactic guidance for precise targeting.
Usage
Usage note: Distinguish from therapeutic resection procedures in surgical reports.
