RESUMO

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; 87.5%). Most patients (17; 53.1%) were diagnosed as having Child class B cirrhosis. Single tumors measuring <3 cm were diagnosed in 29 (90.6%) patients. Downstaging chemoembolization was performed in 7 (21.8%) patients. Preoperative aFP levels were normal in 20 (62.5%) patients. In the rest (n = 12; 37.5%), aFP levels normalized immediately after the OLT. In the latter group, 2 patients had a delayed (2 years) postoperative increase in aFP levels; both patients had tumor recurrence in the graft. All patients with hepatitis B received antiviral treatment with HBIG and lamivudine. There were 9 deaths (28.1%) in the immediate postoperative period (<30 days). One-year survival rate was 62.5% (n = 20). Actuarial 5-year survival rate was 55%, and actuarial 10-year survival rate was 40%. In conclusion, OLT has become the standard treatment for patients diagnosed with HCC in a population that shows cirrhosis most of the time to be secondary to viral hepatitis, provided that recipients are selected according to the size of the neoplasm and that they receive adequate antiviral prophylaxis.

RESUMO

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. The median DAP values for carotid arteriography and lower limb arteriography were 66 and 123 Gy cm2 for hospital 'A' and 21 and 49 Gy cm2 for hospital 'B'. For the cerebral arteriographies performed in hospital 'A', the median DAP was 116 Gy cm2, while for the hepatic embolizations performed in hospital 'B', it was 104 Gy cm2. The DAP values observed in hospital 'A' for carotid arteriography and lower limb arteriography were almost three times than those of hospital 'B'. From the data analysis, it is evident that dose optimization in hospital 'A' should be pursued through revision of the techniques used.

RESUMO

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. Occasionally, focal areas of normal parenchyma in an otherwise diffuse fatty liver may simulate mass lesions. Typically, these "pseudolesions" appear as echo-poor areas against a background of bright echoes due to fatty infiltration and may pose a difficult diagnostic problem. We present this case and discuss the investigation process in order to differentiate this lesion from a hepatic tumor.

RESUMO

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. The efficacy of this treatment and the problems that arose during his hospitalization are being discussed.

RESUMO

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. Histologic confirmation was established after unilateral adrenalectomy in three patients. In two patients with adrenal tuberculosis, long clinical and laboratory follow-up confirmed the diagnosis. This report indicates that Addison's disease is not infrequently associated with adrenal enlargement. Adrenal size is related to the cause and duration of the various disease states leading to adrenal insufficiency. Moreover, adrenal insufficiency associated with enlarged adrenal glands can be the presenting manifestation of lymphoma or metastasis.

RESUMO

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.

RESUMO

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)]. In 47 of 59 patients this extension was confirmed by surgery or aspiration biopsy. Three discrete anatomic groups of lymph nodes were recognized producing a relatively distinct CT configuration when involved: (a) the hepatoduodenal seen in 49 patients; (b) the peripancreatic demonstrated in 33 patients; and (c) the aortocaval recognized in 16 patients. These groups of lymph nodes can be seen individually involved or in combination. Recognition of involvement of these nodes is important for correct diagnosis and staging of upper abdominal malignancies. The development of this involvement follows the natural flow of lymph via the lesser omentum to the retroperitoneal space.
