[Effect of hemorheology in the post-operative period]

Very important hemorheological changes characterize the early post-operative period. This research, performed on a group of 10 patients who underwent aorto-ilio-femoral revascularization, enables us to observe that these changes are present also in vascular surgery. In fact, plasma fibrinogen, red cells aggregation and deformability, whole blood viscosity, already modified in the pre-operative period in patients with peripheral arteriopathy, resulted significantly impaired on the 2nd and 6th day after the operation. Such changes must be considered in order to avoid ischemic consequences on microcirculation, the possible onset of deep vein thrombosis as well as an impairment of the prognosis of vascular operations (early and late reobliteration), and in order to perform an adequate and prophylactic corrective treatment.
