Elaborare in sardo, elaborare in italiano. Una ricerca nella scuola media.
No full textL'articolo presenta i dati di una ricerca condotta in provincia di Sassari, su alunni di scuola media, applicando uno schema sperimentale già utilizzato in ricerche condotte in regioni dell'Italia meridionale, al fine di valutare i possibili effetti del tipo di codice utilizzato, lingua nazionale o dialetto, sulla produzione di testi. I risultati confermano in gran parte gli esiti precedenti, pur con alcune specificità dal punto di vista semantico, legate a caratteristiche del contesto sardo
Color Doppler sonography of intrahepatic vascular shunts
No full textPurpose.
To illustrate the sonographic and Doppler features of the different types of intrahepatic vascular shunts.
Methods.
Patients presenting in our department with intrahepatic vascular shunts with healthy livers or with a variety of liver pathologies underwent color Doppler interrogation and spectral analysis.
Results.
Intrahepatic vascular shunts may involve all liver vessels. Arterioportal and arteriosystemic venous connections can be recognized in normal and cirrhotic livers, following trauma, within tumors, and within nontumoral arteriovenous malformations. Portosystemic intrahepatic venous shunts are categorized into 4 morphologic types. Systemic-to-systemic shunts are more often recognized in patients with chronic hepatic venous congestion or with Budd-Chiari syndrome. Portal-to-portal intrahepatic venous shunts are rare, with few cases described.
Conclusion.
In general, all the liver vessels can be associated with formation of arterioportal, arteriosystemic, and portosystemic venous shunts and, rarely, systemic venous shunts and portal-to-portal communications. Sonography allows characterization of the different intrahepatic shunts
