[Solitary fibrous liver tumor: clinical, radiological and pathological characteristics].

A solitary fibrous liver tumor is a rare disease which is difficult to diagnose. Radiological findings are not specific, and cannot confirm benignity or malignancy. Treatment most often involves a major hepatic resection.

[Acute thrombosis of the portal system. Treatment with alteplase and heparin or with heparin alone in 10 patients].

Objectives: We report the efficacy of alteplase (a recombinant tissue plasminogen activator) with heparin or heparin alone in the treatment of acute thrombosis of the portal venous system.

Methods: Ten consecutive patients with acute portal venous system thrombosis were studied. Five patients were treated with alteplase and heparin, and the remaining 5 patients, who were asymptomatic or had a contraindication to alteplase, were treated with heparin alone.
