Abstract

Objective

The aim was to assess the role of intraoperative ultrasound in intracranial space occupying lesion.

Methods

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.

Observations

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.

Conclusion:

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.
