Background and aim: The term porto-sinusoidal vascular disorder (PSVD) was recently proposed to replace that of idiopathic non-cirrhotic portal hypertension (INCPH) to describe patients with typical histological lesions in absence of cirrhosis, irrespective of the presence/absence of portal hypertension (PH), and new diagnostic criteria were defined. The study aimed to compare the applicability between the diagnostic criteria of PSVD and those of INCPH. Materials and 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.

Abstract

Background and aim: The term porto-sinusoidal vascular disorder (PSVD) was recently proposed to replace that of idiopathic non-cirrhotic portal hypertension (INCPH) to describe patients with typical histological lesions in absence of cirrhosis, irrespective of the presence/absence of portal hypertension (PH), and new diagnostic criteria were defined. The study aimed to compare the applicability between the diagnostic criteria of PSVD and those of INCPH. Materials and 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.
