Paper Abstract

From January 1989 to December 1993, in the Neurosurgery Department of Mine Hospital in Sosnowiec, a Nd:YAG mediLas 4060 N (MBB) laser with the radiation wavelength of 1.064 micrometer was used for operation of 104 patients with intracranial neoplasm. Fifty-five patients were operated on without any use of the Nd:YAG laser. The coagulation capabilities of the Nd:YAG made it possible to achieve the hemostasis sooner and more certainly that brought an opportunity operate in a dry field. The shrinkage of a tumor, especially in the cases of meningioma and metastases, facilitated their preparation to a great extent. Removal of a lesion took place with negligible mechanical damage of the surrounding cerebral tissue. The Nd:YAG laser is particularly useful in the cases of well vascularized brain meningiomas; in this way larger tumors can be removed radically with milder postoperational course and good results of therapy were achieved significantly more frequently than in the control group. It was clearly demonstrated with significantly less frequent bouts of consciousness disturbance and pareses. The application of this Nd:YAG laser does not influence upon the postoperational course, the tumor regrowth and the number of persons with the expanding process recurrence in the glioma cases.
