RESUMO
Purpose: To report the treatment result of astrocytoma of the brain treated by operation combined radiotherapy. Materials and Methods: 70 patients with brain astrocytoma were treated by radiotherapy after operation from January, 1978 to January, 1989. The radiation dose ranged from 40～64Gy/5～7wks. Results: The 1-,3- and 5-year survival were 91.7%,55.8% and 45.0%,respectively. Conclusion: Radiotherapy is necessary for patients with brain astrocytoma after operation.
RESUMO
The thoracic aorlae of 39 goats and the inferior venae cavae of 9 goats were anastomosed experimentally with the Large Blood Vessel Anastomat. The pathological changes of these vessels were observed dynamically within one year after the operation. It was found that the Large Blood Vessel Anastomat was rather effective. The vessels anastomosed with this instrument showed a better result than those anastomosed with manual suture.
