BackgroundHaemodialysis arteriovenous fistulas have common local and regional complications, but are rarely associated with neurological symptoms.Case reportA 43-year-old woman presented with short acute episodes of unilateral, non-throbbing, severe headache, vertigo and left lateropulsion. She had undergone renal transplantation and had a still-functioning left brachial arteriovenous fistula. No abnormality was detected on neurological examination or on brain parenchymal imaging. Colour Doppler ultrasonography showed a subclavian steal syndrome of the left vertebral artery and reversed flow in the left internal jugular vein. Ligation of the arteriovenous fistula had to be delayed as a result of renal graft dysfunction. Six months later she developed a headache attributed to intracranial hypertension. All symptoms subsided after ligation of the arteriovenous fistula.Literature reviewWe identified 16 case reports of central neurological complications attributed to haemodialysis brachial fistulas.
