Summary
The use of a 20 MHz pulsed Doppler technique during stereotactic brain tumour biopsies is described. By means of a miniaturized ultrasonic probe the tissue planned for biopsy was investigated for vessel signals. Out of 41 patients, with this technique a flow-pulse curve in front of the biopsy cannula was registered in 14 cases. In 9 cases one pulse curve was determined and in 5 cases two or more flow curves were found, indicating the presence of arterial vessels. The depth of the vesses signal could be localized and this area avoided for biopsy sampling. In a series of 41 Stereotactic biopsies carried out in this way there was no intra-operative haemorrhage or postoperative haematoma.
