Background/aims: To identify prevalent causes and determine survival rates of patients with portal vein thrombosis (PVT) in the Western Saudi Arabia.
Methodology: Retrospective chart review of patients diagnosed with chronic liver disease and portal vein thrombosis in two major cities in Western Saudi Arabia during the period 2000-2009.
Results: Among 1349 patients screened, 109 patients met the inclusion criteria, 67 patients had acute PVT and 42 patients had chronic PVT. The relative risk of developing PVT is higher in males in whom acute PVT is 1.32 vs. 0.68 in females (95% CI: 090-1.94). Mean survival age of acute and chronic PVT (Kaplan-Meier) is 5.61 years (95% CI: 4.52-6.70). Univariate and multivariate regression analysis identified several variables in which international normalized ratio (INR) level on presentation was found to be a significant variable in survival.
Conclusions: Mean survival for acute or chronic PVT is about five years. The first determination of INR level is a useful predictor of survival.

Department of Radiology, West China Hospital, Sichuan University, Chengdu, PR China. Electronic address:
Congenital extrahepatic portosystemic shunt, also known as Abernethy malformation, is a rare anatomic vascular malformation. Patients with Abernethy malformation may present with abdominal pain, abnormal liver function tests, hepatopulmonary syndrome, pulmonary hypertension, and/or portosystemic encephalopathy. Accurate identification of the shunt and portal vein and effective management of complications is vital in these patients.

HuaShan Hospital, Fudan University, Shanghai, China, Shanghai, China.
Background: To investigate the physiological clearance of circulating Aβ by the liver and its role in the pathogenesis of Alzheimer's disease (AD).
Method: Immunostaining, near-infrared imaging, and flow cytometry were used to explore the physiological clearance of Aβ by the liver and the impact of aging on Aβ clearance. Liver-specific LRP-1 knockdown and functional LRP-1 minigene (mLRP-1) expression in mice with AD were used to explore the effects of hepatic Aβ clearance on AD pathogenesis and treatment.

Background And Aims: We assessed clinical, procoagulant and genetic risk factors and clinical outcomes in dabigatran-treated patients with non-tumoural acute and acute-on-chronic portal vein thrombosis (PVT).
Methods: Patients with a new diagnosis of non-tumoural acute and acute-on-chronic PVT between January 2021 and January 2024 (aged ≥ 18 years) in those without/with cirrhosis (Child-Pugh (CP)-A/B/C ≤ 10) were started on dabigatran and followed and compared with those on vitamin K antagonist (VKA) and untreated individuals.
Results: Dabigatran was prescribed in 119 patients with PVT type 1 (61, 51.

Background: Splanchnic vein thrombosis (SpVT) occurs in 17%-23 % of acute pancreatitis cases. Serious sequelae include hepatic and bowel ischaemia. However, management with therapeutic anticoagulation remains controversial due to potential bleeding risk.

Abdominal Surgery and Transplantation Department, Cliniques Universitaires Saint-Luc, Brussels, Belgium.
Background: The Resection and Partial Liver Transplantation with Delayed Total Hepatectomy (RAPID) procedure for unresectable colorectal liver metastases (uCRLM) has renewed interest by increasing, in selected cases, patients' long-term survival. Initially described using deceased donor graft, this technique evolved to living donors, tackling organ-shortage issues, allowing better scheduling, and reducing liver failure risk.
Methods: A 50-year-old patient presented 18 months earlier with a colic adenocarcinoma with synchronous uCRLM.
