AI Article Synopsis
- Portopulmonary hypertension (PoPH) is a serious complication linked to portal hypertension, especially in patients with liver cirrhosis, but is often underdiagnosed due to the variety of symptoms like dyspnea.
- A comprehensive case study highlights the use of advanced imaging techniques, including dual energy CT and pulmonary perfusion imaging, to effectively diagnose PoPH.
- This refined imaging protocol provides a noninvasive, efficient way to evaluate PoPH, complementing standard chest evaluations.
Article Abstract
Pulmonary arterial hypertension associated with portal hypertension, known as portopulmonary hypertension (PoPH) is one of the important and serious pulmonary complications in patients with portal hypertension. Although there are a large number of patients with portal hypertension due to mainly liver cirrhosis, the number of cases diagnosed with PoPH are far fewer because the causes of dyspnea in patients with cirrhosis are diverse and the disease entity of PoPH is poorly recognized by clinicians. We report here the case with PoPH suggested and assessed comprehensively by dual energy computed tomography (CT) including high-resolution pulmonary CT angiography, pulmonary perfusion imaging, myocardial late iodine enhancement imaging, and myocardial extracellular volume analysis. This refined CT imaging protocol can be used in conjunction with standard chest evaluation and offers a practical and useful approach for the noninvasive "one-stop shop" evaluation of PoPH.

Hepatocellular carcinoma (HCC), the most common primary liver cancer, is a highly aggressive malignancy with limited viable therapeutic options. For early HCC, resection surgery is currently the most effective treatment. However, in advanced stages, resection alone does not sufficiently address the disease, so finding a method with a better prognosis is necessary.

Purpose: To assess the activity and toxicity of hepatic arterial infusion chemotherapy (HAIC)+tislelizumab+lenvatinib (HAIC+tisle+len) in hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT) type IV (Vp4 hCC) in a real-world context.
Methods: Fifty-five patients, with Vp4 hCC receiving HAIC+tisle+len therapy from April 2021 to December 2022, were analyzed retrospectively. Data on patient characteristics, adverse events (AEs), treatment, and survival were collected.
Background And Aim: There is paucity of data about the prevalence of cirrhosis and portal hypertension in the US general population.
Methods: We used National Health and Nutrition Examination Surveys (NHANES 2017-2020) to estimate the prevalence of cirrhosis and clinically significant (CS)-portal hypertension in alcoholic liver disease (ALD), MetALD, viral hepatitis (VH) to include chronic hepatitis B (CHB) and chronic hepatitis C (CHC), and metabolic dysfunction-associated steatotic liver disease (MASLD). Cirrhosis was evaluated using liver stiffness measurement (LSM) by transient elastography or FIB-4 score; CS-portal hypertension was defined via LSM and platelet count or the use of non-selective beta-blockers in the presence of cirrhosis.

Goals: To explore dynamic contrast-enhanced ultrasound (CEUS) parameters in predicting hepatic vein pressure gradient (HVPG) for patients with liver cirrhosis (LC).
Background: Noninvasive diagnosis of HVPG remains a challenge.
Study: This prospective study included patients with LC undergoing hepatic vein catheterization and pressure measurement at the hospital from May 2021 to January 2023.
Machine learning prediction of hepatic encephalopathy for long-term survival after transjugular intrahepatic portosystemic shunt in acute variceal bleeding.

Department of Radiology, Nanfang Hospital, Southern Medical University, Guangzhou 510151, Guangdong Province, China.
Background: Transjugular intrahepatic portosystemic shunt (TIPS) is an effective intervention for managing complications of portal hypertension, particularly acute variceal bleeding (AVB). While effective in reducing portal pressure and preventing rebleeding, TIPS is associated with a considerable risk of overt hepatic encephalopathy (OHE), a complication that significantly elevates mortality rates.
Aim: To develop a machine learning (ML) model to predict OHE occurrence post-TIPS in patients with AVB using a 5-year dataset.
