[Intrahepatic presinusoidal portal hypertension in a female patient with chronic lymphatic leukemia]. / Ipertensione portale presinusoidale intraepatica in una paziente con leucemia linfatica cronica.

A rare case of intrahepatic presinusoidal portal hypertension, due to massive infiltration of portal zones by chronic lymphatic leukaemia, revealed by sonographic patent umbilical vein, is reported. Sonographic patent umbilical vein which is considered specific for portal hypertension in liver cirrhosis may be present in myeloproliferative syndromes with liver involvement too.

[An echocardiographic study of the isovolumetric relaxation period in the myocardial infarction (author's transl)]. / Studio ecocardiografico della diastole isovolumetrica nell'infarto cardiaco.

Variations have been examined in the left ventricle's transverse dimension (TD) during the isovolumic relaxation period (IRP) in 12 healthy subjects and in 38 patients with anterior or antero-inferior infarct. Healthy subjects have shown no increase in TD during the IRP whereas this fact has been noted in 24 out of 38 (63%) patients with different distribution according to the site of the infarct (29%) for inferior infarcts and 86% for anterior or antero-inferior infarcts). These results suggest that inferior infarct compared with anterior infarct, implies a less incoordinate ventricular contraction. It is thus stressed the opportunity of echocardiography approach for the identification of the incoordinate ventricular contraction and for the determination of IRP duration which may be exposed to serious mistakes using the traditional phono-apexcardiographic method.
