title: Changes in splenoportal axis calibre and flow in a patient affected by hereditary angioedema.
abstract: The authors describe a case of hereditary angioedema characterised by abdominal pain accompanied by ascites. Ultrasound (US) examination performed after acute abdominal attack implied the presence of increased splenoportal axis calibre and reduced blood flow. According to the authors, this may confirm the pathogenic role of C1-inhibitor deficiency induced oedema that is capable of creating major haemodynamic involvement also of abdominal vessels. US findings of transient appearance, especially related to the specific treatment, may help physicians make early diagnosis and avoid dangerous invasive procedures resulting from incorrect diagnosis of acute abdomen.
