The aim of this study was to examine the clinical presentation and time of hepatic artery thrombosis (HAT) after orthotopic liver transplantation (OLT), stressing the role of imaging modalities. Therapeutic options are described, such as retransplantation (Re-OLT), hepatic resections and revascularization procedures, focusing on complications and outcome in a consecutive series of 687 OLT. Over the period from 1986 to 1999, 687 OLT were carried out in 601 patients, 592 of whom were adults and 95 pediatric subjects. ⋯ Although the results of OLT have improved dramatically over the past few years, HAT is still associated with substantial morbidity, a high incidence of graft failure and high mortality rates. The use of DUS to screen for HAT has permitted earlier diagnosis, but early angiographic evaluation of the hepatic arteries is still needed for accurate diagnosis of HAT and remains the gold standard. Retransplantation is the definitive solution for HAT in the majority of cases, though it is essentially the patient's clinical condition that dictates the form of management.

In some types of cancer (breast, lung) a malignant pleural effusion may be present during the evolution of the neoplastic disease in more than 50% of cases. The main therapeutic option for palliative purposes in these cases is chemical pleurodesis with talc. The aims of this study were to report on our experience with the use of pleurodesis with talc in the treatment of patients affected by malignant pleural effusions and to analyse the results in the short and mean term. ⋯ Two patients died within the first month as a result of progression of the neoplastic disease and one patient was withdrawn from the study owing to failure to collaborate. Of the other 13 patients, 11 (84%) had a total or partial response to the pleurodesis; in 9 of these patients (69.2%) the response remained stable until death, while in 2 patients the pleural effusion reappeared after 3 and 5 months, respectively. Failure of the pleurodesis occurred in 2/13 patients owing to reappearance of the pleural effusion within the first month.
