[Correlation between sequential changes in angiographical findings and clinical deteriorations during management for dural AVM of the cavernous region].
The authors treated five patients with dural arteriovenous malformation of the cavernous region (DAVM) by cervical compression procedure as the initial treatment. In four of five patients clinical symptoms were aggravated during that period. The period between the beginning of cervical compression and the deterioration of clinical symptoms ranged from 11 to 20 days. In three of four patients, the angiography examined at the time of deteriorations confirmed the same amount of A-V shunt flow and otherwise the remarkable decrease of the draining pathway compared to the findings of the angiogram performed before the management. The angiography examined at the time of the remission of the symptoms showed the increase of the draining pathway in two patients and the resolution of the DAVM in another. These findings indicate that clinical courses of the DAVM and the amount of the draining pathway correlate to each other and that cervical compression procedure may occlude the important draining pathway of the DAVM.
