[The role of radionuclide phlebography in the detection of deep venous thrombosis in the lower extremities and pelvis and in establishing indications for implantation of a caval filter].

In all 40 patients with pulmonary thromboembolism (PTE) radionuclide phlebography (RNP) detected deep venous thrombosis (DVT), most commonly in the left iliac veins, in 20 (50%). RNP and contrast phlebography (CP) were performed in 18 patients and RNP sensitivity was found in 100% in all localizations of DVT and the largest specificity was obtained in the left side of the pelvis, in 92%. In 12 out of 18 patients cava filter was implanted and BNP specificity in the left upper leg reached 100% and in the right one 89.3%. In establishing indications for cava filter implantation RNP should be performed first so that by detecting embologenous TDV localizations the risk of jatrogenous PTE at cava filter implantation would be avoided or CF, if necessary.
