Role of intraoperative ultrasound in achieving complete resection of intra-axial solid brain tumours.

Objectives: To determine the frequency of completeness of resection for intra-axial solid brain tumours with the help of intra-operative ultrasound to detect residual brain tumour.

Methods: The cross-sectional study was conducted at the Department of Neurosurgery, Dow University of Health Sciences and Civil Hospital Karachi, from September 2009 to June 2010 and comprised patients with intra-axial solid brain lesion. During operation following standard craniotomy, multi-plane sonographic examination was performed using intra-operative ultrasound for tumour localisation and calculation of dimension, followed by tumour resection in the standard fashion.
