Testing minimal transit time in the venous system of the lower limbs using dynamic radionuclide venography.

The Authors used a test of venous occlusion applied during plethysmography in performing radionuclide venography. The minimal transit time of maximal venous outflow was tested in the subinguinal region using 99mTc-DTPA. Significant differences could be observed in compensated and non-compensated cases of occlusion of the iliac vein and chronic venous insufficiency caused by primary varicosity if compared to the controls. The functional change of suprapubic venous bypass was examined after Palma operation. Such a dynamic bolus radionuclide venography is considered to be suitable for extending the preoperative selective methods of reconstruction operations and monitoring patients postoperatively.
