Abstract
Sixteen patients with recent cerebral infarction have been studied. Ten of them under,’rent hemodilution by means of erythroapheresis and have shown an increase of cerebral blood flow (CBF) and of the arterial oxygen pressure (PaO2). The oxygen delivery capacity showed no significant variations. The hemorheological parameters have been improved without a significant correlation with CBF. Furthermore the treated patients have shown a better short term clinical outcome than the untreated patients. This finding seems to indicate that the rheology of the blood is an important factor in cerebral vascular disease and that its modifications may have a useful therapeutic effect provided that all other determinants of CBF are not negatively modified.
