[Angiomatosis of the liver].

Cavernous haemangioma of the liver is the most frequently observed benign hepatic tumour. Polyangiomatosis is a great rarity, and in view of the similarity to metastatic tumours, it is a serious diagnostic problem. In the paper three cases are described of polyangiomatosis of the liver diagnosed on the basis of abdominal ultrasonography.

[Isotope methods in diagnosis of portal vein occlusion].

The dynamic intravenous hepato-scintigraphy with pertechnetate Tc-99m enables a quantitative evaluation of portal and arterial blood flow in the liver. A case is presented of thrombotic occlusion of the portal vein with rapidly growing oesophageal varices in which hepato-scintigraphy showed the absence of portal blood flow in the liver, being the decisive diagnostic method. Using the dynamic transrectal porto-scintigraphy an evaluation was done of the degree of collateral circulation development in the area of the inferior mesenteric vein, obtaining indirect information about localization and duration of portal vein occlusion.

[Static and dynamic scintigraphy of the liver using labeled erythrocytes in the diagnosis of hepatic hemangioma].

In order to find hemodynamic differences between hemangioma (n = 10) and other tumours of the liver (n = 15) dynamic angioscintigraphy and late vascular scintigraphy of the liver were performed. Late vascular scintigraphy has revealed focal cumulation of the labelled erythrocytes in 7 hemangiomas of the diameter of 35 mm, 3 hemangiomas below this size have not been diagnosed with this technique. Beside hemangiomas, a focus of erythrocytes cumulation was found also in the hepatocellular adenoma.

Clinical utility of quantitative assessment of liver haemodynamics in cirrhosis provided by dynamic hepatoscintigraphy.

Interrelationships between quantitative assessment of portal (%Qp) and arterial (%Qa) components of hepatic blood supply obtained by dynamic hepatoscintigraphy, and clinical variables characterizing the severity of liver cirrhosis and portal hypertension were studied in 25 cirrhotic patients. The variables, clinical state, size of oesophageal varices, ascites accumulation, sonographic stigmata of portal hypertension, liver mass and elimination rate of lidocaine and antipyrine were studied. The %Qa rose in proportion to the severity of liver injury estimated from the Child-Turcotte and McCormick grading scores.

[Giant hepatic hemangioma--diagnostic value of radioisotope investigations].

In an example of a 60-year-old female patients with a giant hepatic haemangioma the authors discuss the diagnostic possibilities of radioisotope angiography in the detection of this vascular pathology. In confrontation with ultrasonographic examinations, computerized tomography, laparoscopy and even coeliac angiography only later hepatic scintigraphy using labelled erythrocytes was of decisive diagnostic importance.
