Dural Arteriovenous Fistula Presenting with Cerebral Infarction

ABSTRACT

We report on a diabetic 52-year-old man who complained ocular floating sensation, headache and dizziness, in whom a left parieto-occipital dural ateriovenous fistulas (DAVFs), fed by bilateral superficial temporal arteries and occipital artery, drained into the cortical vein of the left parieto-occipital convexity. Because the patient's chief complaint was ocular symptom for diabetic retinopathy, we initially didn't consider an DAVFs until brain magnetic resonance imaging (MRI) was done. Diffusionweighted brain MRI revealed acute cerebral infarction and microhemorrhage in the lesion. Transarterial embolization with mixture of glue and lipiodol obliterated the DAVFs completely. Although the DAVFs fed by multi-arteries, the fistulous portion has been disappeared after embolization via an only left occipital artery. Endovascular embolization of the fistula led to symptomatic improvement, except ocular discomfort.
