  • Title: [The diagnostic value of radionuclide inferior veno-cavagraphy in Budd-Chiari syndrome].
    Author: Dong JT, Huang MJ, Kao PF.

    Abstract:
    To evaluate the diagnostic value of radionuclide inferior veno-cavagraphy (RIVC) for Budd-Chiari Syndrome, RIVC using Tc99m was performed on 106 patients with massive ascites. A positive RIVC result was defined as having at least two of the three following criteria: (1) a delay of more than 4 seconds in visualizing the heart; (2) sharply truncated inferior vena cava with marked hang-up of isotope activity; and (3) extensive collateral circulation. Of the 106 patients, 18 were RIVC positive and were later confirmed by operation or contrast venography to have Budd-Chiari Syndrome with IVC obstruction. Of the remaining 88 RIVC negative patients, 3 were shown by operation, computerized tomography and cardiac echo, respectively, to be Budd-Chiari Syndrome with IVC obstruction. Thus, the diagnostic sensitivity and specificity of RIVC for this syndrome was 85.7% and 100% respectively. If RIVC is combined with hepatic scintigraphy, it will help to elucidate the anatomic and functional change of IVC, as well as, liver parenchymal disease, such as liver cirrhosis, hepatic tumor or hepatic vein obstruction. RIVC is a simple safe, accurate, noninvasive and reproducible procedure. This study confirms the high diagnostic specificity and sensitivity of RIVC. We therefore recommend RIVC as the first-line study for IVC patency. Contrast venography may be used as a confirmatory study in preparation for surgical intervention.
