Sixty-eight patients presented with one or more symptoms,including homonymous visual disturbances in 39,seizures in 20,and hemorrhage in twenty-six.Visual field loss was more common(p=0.0007)and more severe(p=0. 0002)in patients who bled than in those with unruptured AVMs(16/44).The frequency of visual field loss was not associated with a hemorrhage.Forty- six patients were treated with embolization,surgery,radiosurgery,or a combination of therapies.The AVM was eliminated in 19of 20 patients(nine with preoperative partial embolization)treated with surgery versus in 4 of 27 patients treated only with embolization.There were two AVM-associated deaths,two subarachnoid hemorrhages,and four new neurologic deficits after treatment.Visual fields were worse in 15 patients,unchanged in 22,and improved in eight.Whereas some features of headache and visual symptoms are similar for occipital AVMs and migraine,the two disorders are usually distinguishable.Visual field improvement can spontaneously occur in patients who have had loss secondary to an intracerebral bleed.Treatment with embolization or surgery,particularly with surgical excision of the AVM,can result in new or worse visual field loss. |
