OBJECTIVE:
The purpose of the present study is to analyze and represent our experience in operative treatment of brain metastases with image guided US real-time techniques.
MATERIAL AND METHODS:
Within a 4-year period (01.01.2002-31.12.2005) in our NS Department have been performed 87 US guided surgery for 83 patients. IOUS were used by B-mode US unit GE with three types of probes-microconvex, I-type and T-type.
RESULTS:
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 recedives in 4 cases for period of 6 months to 2 years.
CONCLUSIONS:
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 in?uence of the so called “brain-shift phenomenon”. IOUS makes the surgery minimum invasive, predominantly in the functional important brain areas.
