Comparison of patient doses in interventional radiology procedures performed in two large hospitals in Greece.

Purpose of the study was to determine patient doses in the most common interventional radiology (IR) procedures performed in two large Greek hospitals. A total of 164 patients who underwent 4 types of IR procedures were studied. Fluoroscopy time, total exposure time, number of frames, number of runs, radiation field size, and cumulative dose-area product (DAP) were recorded.

Liver transplantation outcomes in patients with cirrhosis and hepatocellular carcinoma: experience of a single center in a viral hepatitis endemic area.

Our center has performed 205 orthotopic liver transplantations (OLT) in 201 patients. Hepatocellular carcinoma (HCC) was discovered in 32 (15%) patients, 5 of whom were diagnosed incidentally in recipient explants. The main underlying diagnosis was viral hepatitis (n = 28; 87.

Focal fatty liver sparing lesion presenting as a "pseudotumour": case report.

We are reporting our experience of a case of "focal fatty liver sparing lesion" in a 24-year-old patient, without any evident predisposing factors for fatty infiltration of the liver. Fatty liver infiltration was sparing the posterior part of liver segment VI, defining an area which was mimicking a lesion on US and CT. Fatty liver infiltration is usually diffuse but may be patchy or localized.

Management of acute bleeding in a patient with congenital afibrinogenaemia.

Congenital afibrinogenaemia is a rare bleeding disorder characterized by absence of fibrinogen and varying bleeding tendency. Treatment with fibrinogen concentrates is considered to be the best choice for afibrinogenaemic patients who experience bleeding. We report the case of a 22-year-old Greek patient who presented with large muscular haematomas and was treated with fibrinogen concentrates.

Pathways of lymph node involvement in upper abdominal malignancies: evaluation with high-resolution CT.

The aim of this study was to enhance our understanding of the pathways of lymphatic spread of primary carcinomas in the upper abdomen by recognizing the development, configuration, and frequency of nodal enlargement in discrete anatomic regions. The study included 417 patients with histologically confirmed carcinomas (CC) of the stomach (n = 267), liver (n = 98), gallbladder (n = 25), and bile ducts (n = 27). All patients were studied by high-resolution CT and tumor extension to the lymph nodes of the subperitoneal space was clearly identified in 59 patients [33 with CC of the stomach, 8 with CC of the gallbladder, 3 with CC of the bile ducts, and 15 with hepatocellular carcinoma (HCC)].

Adrenal insufficiency with enlarged adrenals.

Five patients with adrenal insufficiency and large adrenal glands at presentation are reported. Addison's disease was due to adrenal tuberculosis in three patients, with important changes in adrenal configuration on CT reflecting the natural history of the disease. Adrenal infiltration by non-Hodgkin lymphoma and metastatic carcinoma of the lung was the cause of the disease in the fourth and fifth patients, respectively, who developed signs of adrenal insufficiency before the diagnosis of the primary lesion became apparent.

Abdominal scanning with technetium-99m pertechnetate localizes ectopic gastric mucosa in the jejunum: case report and review of the literature.

A 16-year-old male patient was admitted to hospital because of a fainting episode which was accompanied by diarrhoea that was dark red. All investigations were normal except a low haematocrit, a technetium-99m pertechnetate abdominal scan, which showed a large area of moderate activity in the upper left abdomen, and digital subtraction angiography, which showed bleeding in the same area where the abnormal finding on the pertechnetate scan was found. Ectopic gastric mucosa and a deep ulcer in an otherwise normal jejunum were found during the urgent exploratory laparotomy.
