Reflections upon the nature and management of intracranial and intraspinal vascular malformations and fistulae.

摘要: ✓ Evidence is presented that dural fistulae are preceded by sinus thrombosis and their danger lies in arterialized venous pressure within the cranium or orbit. Arterial side occlusion leads to recurrence, while permanent cure. Vein of Galen aneurysms embrace some features cerebral arteriovenous malformations (AVM's), namely a reticulum, fistulae, evidence previous anomaly direct drainage into sinus. These also permanently cured thrombosis, although dangers inherent reticulum demand this be done stages arterial embolization. A very limited experience with end (and spinal) AVM's suggests they, too, can without excision. Their demands maximum, multistage, preliminary embolization together intraoperative hypotension during occlusion...
