Background: Cirrhosis is one of the major causes of morbidity and mortality worldwide and the second leading cause of digestive disease mortality. Portal hypertension is the main driver of cirrhosis-related complications such as ascites and variceal bleeding. Portal hypertension is defined as a hepatic venous pressure gradient >5 mm Hg, although it is clinically significant and associated with clinical complications when >10 mm Hg.
Summary: Therefore, detection of clinically significant portal hypertension (CSPH) in chronic advanced liver disease or compensated cirrhosis is of paramount importance to guide the management of these patients.
Key Messages: This study aimed at revising the non-invasive and invasive tools for assessment of portal hypertension and risk stratification for CSPH in patients with chronic liver disease.

Portal hypertension (PH) is the initial and main consequence of liver cirrhosis. Hepatic venous pressure gradient (HVPG) measurement has been widely used to estimate portal pressure gradient (PPG) and detect portal hypertension. However, some clinical studies have found poor correlation between HVPG and PPG, which may lead to the misdiagnosis of portal hypertension.

Purpose: This study assesses the efficacy and safety of Portal Vein Recanalization with Intrahepatic Portosystemic Shunt (PVR-TIPS) in non-cirrhotic patients with chronic portal vein occlusion (CPVO), cavernomatous transformation, and symptomatic portal hypertension (PH) and/or portal vein thrombotic progression.
Material And Methods: Medical records of 21 non-cirrhotic patients with CPVO and portal cavernoma undergoing PVR-TIPS were analyzed. Hemodynamic (intraprocedural reduction in portosystemic pressure gradient), clinical (data on gastrointestinal bleeding, abdominal pain, ascites, and presence of esophageal varices from imaging exams) and technical success (PVR-TIPS) assessed efficacy.

The use of ultrasound contrast agents (UCAs) for estimating portal pressure has recently gained attention due to its clinical promise, yet variability in acoustic amplitude poses challenges. UCAs contain microbubbles (1-10 µm in diameter), and understanding their acoustic response is essential to address this variability. However, systematic exploration of factors influencing microbubble behavior remains limited in current literature.

Ectopic varices can result from portal vein stenosis following pancreaticoduodenectomy with concomitant portal vein resection reconstruction, and they can cause gastrointestinal bleeding. Although they can sometimes be fatal, various treatments have been reported. This report describes a case in which a percutaneous transhepatic approach was used to simultaneously perform variceal embolization and portal vein stenting in which a favorable outcome was achieved.

Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening systemic hyperinflammatory syndrome, rarely associated with bone marrow failure (BMF). Telomere biology disorders (TBD) are caused by inherited defects in telomerase processes and can have heterogeneous presentations including idiopathic pulmonary fibrosis, cirrhosis, and BMF. We report a case of a 10-year-old male from Lima, Peru, who presented with HLH as the initial manifestation of a TBD.
