[Diagnostic validity of radionuclide phlebography in the detection of clinically occult deep venous thrombosis in patients with thromboembolism].
Diagnostic reliability of radionuclide phlebography (RNP) compared to contrast phlebography in the detection of deep veins' thrombosis (DVT) in patients with confirmed thromboembolism of the lungs (TEL) was evaluated. RNP. These findings were compared to contrast phlebography (CP), performed in the group of 25 patients in whom TEL was confirmed clinically, radiologically, scintigraphically and biochemically, but without clinical signs and symptoms of DVT. In 15 patients where RNP revealed unilateral DVT, CP finding was confirmed in all: in 6 (40%) on the left, and in 9 (60%) on the right side. In 10 patients with bilateral signs of DVT observed by scintigraphy, DVT finding was confirmed in 7 (70%), while in 3 (30%) patients, scintigraphic signs of DVT were falsely positive. In the segments of deep venous system, specificity of RNP in the detection of DVT in the lower leg was 60%, sensitivity was 100%, accuracy was 64% with 62% falsely positive findings. In the upper legs specificity was 79%, sensitivity was 100%, and accuracy was 86% with 24% falsely positive findings, while in the pelvis specificity was 87%, sensitivity was 100%, accuracy was 83% with 14% falsely positive findings.
