[Hemodilution in persistent postphlebitic ulcers].
By definition, rebel post-phlebitic ulcers are very difficult to cure. However, it has recently been apparent that the classic treatments associated with permanent normovolemic haemodilution are more effective. Two research procedures have been implemented simultaneously to try and explain this beneficial effect of haemodilution, one based on an experimental study of isolated rabbit hearts, and the other on a theoretical model of the blood-flow at capillary level. These studies lead us to believe that a better distribution of tissular oxygenation might be one of the mechanisms responsible for the beneficial effect of permanent normovolemic haemodilution in treatment of rebel post-phlebitic ulcers.
