title: Cerebral borderzone infarcts after phlebotomy.
abstract: We describe a 68-year-old patient with cerebral ischaemia who underwent a phlebotomy to lower an elevated haematocrit (0.61 l/l. The procedure was complicated by the development of a total hemiplegia after two hours. CT scanning showed two borderzone infarcts. We conclude that the plasma volume of patients with cerebral ischaemia and a high haematocrit may be contracted to such an extent that venesection is hazardous. The most appropriate treatment in these patients is expansion of the plasma volume.
