FIELD: medicine.
SUBSTANCE: treatment of glial brain tumours is ensured by partial tumour extraction. During operation photosensitiser is delivered in the cavity formed by partial tumour extraction. Photodynamic laser therapy implies using diode laser of cylindrical diffuser with spherical radiation pattern. Wavelength is 660 nm, power is 100-200 mW.
EFFECT: higher concentration of photosensitiser in cavity of partially extracted tumour, reduced amount of introduced photosensitiser, more uniform radiation of tumour tissue, lower probability of postoperative complications and length of hospital stay.
