Non-invasive diagnosis of portal vein occlusion by radionuclide angiography.

摘要: The accuracy of non-invasive radionuclide angiography in detecting portal vein occlusion was assessed 61 patients--10 with confirmed by conventional portography, 25 chronic liver disease and a patent (mild = 12, severe 13), 26 normal function, who served as controls. median percentage venous flow for the group 8% (range 1-30) (consistent negligible flow) compared 78% (52-87) control subjects (p < 0.005) 68% (61-80) 49% (23-59) respectively patients mild 0.001 p 0.005). At inflow 20%, procedure had specificity 100% sensitivity 90% diagnosing occlusion. Non-invasive provides safe accurate screening method evaluating patency or investigation hypertension before transplantation.
