Popis: | Intracavitary irradiation of intrasellar cystic craniopharyngeomas by stereotactic cyst puncture and injection of radioactive solutions is not yet possible. Therefore we designed a new method which allows such intracavitary irradiation. Its principle is a transphenoidal approach with only a small bony opening of the sella floor, followed by cyst puncture, exclusion of cyst leakage by Metrizamid injection under x-ray control, injection of Y-90-colloid solution at a dosage which delivers a radiation of 200 Gy to the cyst wall, and finally tight closure of the puncture site using fibrin glue and gelfoam. This method has been used in three patients with good results (follow-up 12-15 months) and without complications. Even though long-term follow-up is not yet available, our preliminary results suggest that this method will be useful for future patients with intrasellar cystic craniopharyngeomas. |
