[A new instrument for computerized tomography-guided brain biopsy].
The authors present a new stereotaxic brain biopsy method. After establishment of the CT-and angiographic diagnosis follows the marking of the best suited needle track by means of the CT-scanner Somatom DRG. The trephination is then performed at the operation-theatre during local anesthetization. Repeatedly laying on the CT-table, a low contrasted stereotaxic device is fixed on the patients head. Direction and depth of the puncture are measured and predetermined with an accuracy of +/- 5 mm with a few CT-scans. After guided insertion of a thin-wall nonpaque Teflon-sleeve it is possible to obtain artefactless tomograms or localization control and multiple biopsy probes for histologic evaluation without repeated punctures. Therapeutical interventions may be performed in the same way.
