[Roentgeno-functional comparisons in post-thrombotic disease of the lower limbs]

In patients with the sequelae of acute thrombosis of profound large veins the results of kinetic phlebotonometry, venous blood flow rate, tissue hydrophilia, shin electrothermometry and arterial oscillography were compared with the degree of decompensation of the collateral venous outflow, revealed phlebographically. With the development of phlebographic signs of decompensated collateral venous outflow a progressing venous atonia, diminished venous tonus and venous pressure, the valvular apparatus insuffieicny, retardation of the venous blood flow, alterations in tissue microcirculation and insufficient peripheral arterial circulation were detected. The authors' materials allowed a conclusion as to the important role of collateral venous outflow in pathogenesis of postthrombic disease, development of hemodynamic disorders in the involved extremity, and the rationality of using functional methods of investigation to characterize compensatory capacities of the venous network.
