[Portal vein thrombosis after splenectomy].

Elective splenectomies in haematologic malignancies are associated with two serious risks: infection and thrombotic complications. The case of a patient operated on for chronic lymphatic leukaemia with subsequent postoperative portal vein thrombosis is described. The complication was detected using abdominal ultrasonography and was treated successfully with anticoagulants (Fraxiparin).
