The aim was to assess the role of intraoperative ultrasound in intracranial space occupying lesion.
We have performed intraoperative ultrasound in 192 patients
of cranial space occupying lesions admitted at our university hospital.
Intraoperative ultrasound was performed by SonoSite, 180 plus hand carried
ultrasound system with c11/7-4 Mhz curved array transducer probe. A preoperative
Computed tomography or Magnetic resonance was performed in all patients.
Preoperative and postoperative neurological function was assessed.
Intraoperative ultrasound examination is an excellent device
in localizing the small intracranial space occupying lesion. It also helps in
planning the durotomy and extending the craniotomy size if required. It helps in
identifying the shortest and safest site to approach the lesion, and helps in
preventing the damage to eloquent areas. In cases of cystic tumor with small
solid component, it helps in guiding the cyst puncture and exact localization of
the solid component. In cases of large intracranial space occupying lesions,
post excision intraoperative ultrasound helps in delineating the completeness of
resection. Residual tumor if seen in ultrasound was excised.
Intraoperative ultrasound is portable and does not require
any specialized setup. It is cost effective and provides real time images. It
can be repeated as and when required during operation with minimum scanning
time, and ensures patient and operator safety.
