Haemodialysis-induced syncope due to Chiari II malformation.

Spina bifida (SB) is associated with chronic kidney disease as a result of vesicoureteric reflux. A proportion of patients progress to end-stage kidney disease (ESKD). Haemodialysis (HD) is probably the most common modality in ESKD, as intra-abdominal malformations and previous surgery can make peritoneal dialysis more challenging. The Chiari malformations also frequently occur in these patients. We report a case of recurrent syncope induced by HD in a patient with SB and the Chiari II malformation. Sparse data exist on the complications of HD in this patient population and on the approach to the management of dialysis-induced syncope in these individuals.
