The study aimed to compare the applicability between the diagnostic criteria of PSVD and those of INCPH.
METHODS: 53 patients affected by PSVD were enrolled. Biochemical, clinical, ultrasound and histological data, the presence and type of associated diseases were recorded in a database. According to the new criteria, histological data and signs of PH were divided into specific and non-specific. Percutaneous and transjugular biopsies were compared to establish the usability of the two methods for diagnostic purposes.
RESULTS: In 85% of the patients the diagnosis of PSVD was obtained by applying the first criterion (25 had specific histological signs with specific signs of PH); one patient presented with specific histological signs but no PH. In 8 patients the diagnosis was obtained by applying the second criterion. 19% of patients had portal vein thrombosis. Finally, the prevalence of the various histological lesions was similar between the patients submitted to percutaneous and transjugular liver biopsy.
CONCLUSIONS: The study confirms that the diagnostic criteria of PSVD lead to the inclusion of a greater number of patients than INCPH.
