[en] For 81 surgery was made radical extirpation of the metastatic tumours and the result was registered by us for all patients. For 51 patients was made early postoperative control with CT. For other 21 was made CT and MR control for 6 months period after the surgery. We registered recidivous in 4 cases for period of 6 months to 2 years. IOUS is very useful image guided method allowing constant real-time control of the surgical resection. The techniques eliminates anatomic changes during the neurosurgical operation, without influence of the so called “brain-shift phenomenon”. IOUS makes the surgery minimum invasive, predominantly in the functional important brain areas. (author)
