Abstract

Oedemas obstruct the nourishment of tissues in patients with peripheral arterial occlusive disease (PAOD). However, there is little information available in the literature regarding the degree of compressive pressure ensuring a sufficient perfusion pressure without decreasing the macro- and microcirculation. Aim end method: The aim of this study was to determine the minimum compressive pressure effecting a nontolerable impairment of the macro- and microcirculation. The macrocirculation was measured by determining the ankle pressure using the ultra sound Doppler method. A total of 21 patients diagnosed with PAOD and ankle pressure between 40 and 110 torr were included in the study. For the purposes of analysis the patients were divided intotwo groups: Group A (ankle pressure >65 torr) and Group B (ankle pressure <65 torr). Result: Similar values were obtained in both groups for ankle pressure, tcpO2, and the tcpCO2. LDF-flux (also LDF-speed and -concentration)showed a slight non significant downward trend with increasing pressure. The newly introduced peripheral microcirculatory coefficient pMC, a parameter of microcirculation, estimated using noninvasive NIRP-method exhibited a significant reduction (p less than or equal to 0,001) at compression pressures already between 0 and 20, continuing to 40 torr in both groups. On the whole the pMC value in group B was decreased. The spectral number M-L,M-H reflecting vascular tone and estimated from the frequency histogramm of NIRPwas unchanged. Conclusion: The absence of reduced ankle pressure, tcpO(2),and the tcpCO(2), respectively demonstrates that in PAOD patients a compression pressure of 40 torr does not lead to a significant change in the macrocirculation. However, as reflected by the decreased pMC value, the microcirculation is significantly reduced. It is still not clear whether this reduction in the microcirculation is a contraindication for compression therapyin PAOD.
