Diagnostic Utility of CUSA Specimen in Histopathological Evaluation of Tumors of Central Nervous System (original) (raw)

Neurology India, 2020

Abstract

Introduction: Cavitron Ultrasonic Surgical Aspirator (CUSA) is a technique used for the surgical treatment of tumors that aids the surgeon in highly selective tumor sampling with minimal injury to surrounding tissues. The utility of the tissue obtained from CUSA for histopathological diagnosis of central nervous system tumors is not as well-known as its surgical benefits. Even though a few studies have evaluated the diagnostic accuracy of CUSA specimen, these have dealt with very few cases. Methodology: In this study, we nil analysed 73 cases of CNS tumors (glial and non-glial) where CUSA specimen was available for histopathological examination and compared with findings on conventional samples as gold standard. Results: Most frequent types of artefacts induced by CUSA included tissue breakdown resembling necrosis, empty spaces in tissues, and crush artefacts particularly in cellular tumors, that interfered with interpretation. CUSA samples were found optimal for diagnosis of non-gl...
