[Surgical treatment of arteriovenous malformations of the posterior cranial fossa].

The work is based on analysis of the results of complex clinical examination of 70 patients (48 males and 22 females) treated at the Burdenko Institute of Neurosurgery, Academy of Medical Sciences of the USSR, for arteriovenous malformations in the posterior cranial fossa (AVM PCF). The patients' age ranged from 8 to 50 years. Various types of surgical interventions were performed on 26 patients. The authors suggest an anatomo-surgical principle of grouping AVM PCF, which is based on the findings of radiocontrast diagnostic methods. Problems of the clinical picture and topical diagnosis of AVM PCF are discussed. The indications for surgical treatment of AVM PCF, the surgical approaches to them, and the techniques of total extirpation (16 cases) are determined. The results of palliative operations (6 cases) are analysed. The microsurgical anatomy of anastomoses between AVM and PCF and their importance in surgery for these conditions are described.
