ABSTRACT |
There were 13 cases of occipital lobe arteriovenous malformation(AVM) in a series of 100 intracranial arteriovenous malformations from Jan. 1981 to May 1987.
Occipital lobe AVM's which encompass medial occipital, parieto-occipital, temporo-occipital AVM have distinct clinical and anatomic features. They usually present with bleeding, often accompanied by homonymous visual field deficit or with migrainous headache and seizure is very infrequent. However 4 cases out of 13 cases of our series had the seizure. The malformations were supplied principally by branches of posterior cerebral artery(PCA) but middle cerebral artery(MCA), anterior cerebral artery(ACA) and middle meningeal artery(MMA) were also contributed to the supply in some cases. The goal of surgery is to remove the conglomerated mass without disturbing the visual field. On considering the surgical approach, preservation of the visual field should be always kept in mind. We also discuss the surgical approaches. |
