Comparative evaluation of modern intraoperative diagnostic methods in malignant gliomas of the brain

The following methods were employed: Intravital staining with bromphenol blue (70 patients), radiometry with P 32 (127 patients), echo encephalography (12 patients,) puncture biopsy (18 patients), rheometry (96 patients). Bromphenol blue is injected into the a. cerebri media or the supraclinoidal a....

Summary:The following methods were employed: Intravital staining with bromphenol blue (70 patients), radiometry with P 32 (127 patients), echo encephalography (12 patients,) puncture biopsy (18 patients), rheometry (96 patients). Bromphenol blue is injected into the a. cerebri media or the supraclinoidal a. carotis interna and stains the periphery of malignant tumours and the entire tissue of benign tumours. Radiometry also serves for the intraoperative finding of tumour remainders which must be located at least 20 to 22 mm below the cortex of the brain. Tumour biopsy was carried out with a sharp cannula to avoid deformation of the tissue cylinder. Rheometry proved to be very useful when avoiding the mixing with blood, liquor, and cyst fluid at the measuring tip.
