Aim: Operative ligation of the portosystemic shunt may control hepatic encephalopathy effectively, but the subsequent increase in portal vein pressure (PVP) leads to high mortality. Splenectomy can decrease inflow into the portal system, resulting in decreased portal pressure.
Methods: We retrospectively examined the effect of splenectomy in combination with shunt closure on portosystemic encephalopathy.
Results: Clinical symptoms of encephalopathy disappeared in all six patients who underwent splenectomy in combination with portosystemic shunt ligation, with the exception of one patient who had relapsing encephalopathy after 6 months. Follow-up computed tomography showed complete obliteration of the portosystemic shunts, except in the one patient with relapsing encephalopathy who underwent balloon-occluded retrograde transvenous obliteration for the remaining splenorenal shunt 8 months after surgery. PVP significantly decreased after splenectomy. PVP did not increase to the baseline PVP value after ligation of the shunts, except in two patients who had elevated PVP after surgery: PVP increased from 18 to 19 mmHg after ligation in one patient and from 18 to 23 mmHg in one patient.
Conclusion: Splenectomy followed by surgical ligation of the portosystemic shunt may be feasible and safe for cirrhotic patients with portosystemic shunts.

Gut microbiota shifts in hepatitis B-related portal hypertension after transjugular intrahepatic portosystemic shunt: Mechanistic and clinical implications.
World J Gastroenterol
January 2025
Department of Infectious Diseases, The First Affiliated Hospital of Fujian Medical University, Fuzhou 350004, Fujian Province, China.
In this article, we provide commentary on the recent article by Zhao . We focus on the shifts in the gut microbiota of patients with hepatitis B virus (HBV)-associated cirrhosis/portal hypertension (PH) following transjugular intrahepatic portosystemic shunt (TIPS) and the implications for understanding the mechanisms, diagnosis, and treatment. By comparing the gut microbiota composition and dynamic changes before and after TIPS in patients with and without hepatic encephalopathy, the authors found an increase in non-probiotic bacteria in those who developed hepatic encephalopathy post-TIPS, with species present only in the hepatic encephalopathy group.

Ultrasound Unit, Helen Schneider Hospital for Women, Rabin Medical Center, Beilinson Hospital, Petach Tikva, Israel.
Objective: Portosystemic shunts in growth-restricted fetuses are more common than previously thought. We aimed to describe fetuses with growth restriction and transient oligohydramnios in which a congenital intrahepatic portosystemic shunt (CIPSS) was noted during follow-up.
Methods: This was a retrospective study of all fetuses diagnosed with growth restriction and transient oligohydramnios during a 5-year period in a large tertiary referral center.
Administration of anticoagulation strategies for portal vein thrombosis in cirrhosis: network meta-analysis.

January 2025
Center for Evidence-Based Medicine and Clinical Research, Taihe Hospital, Hubei University of Medicine, Shiyan, Hubei, China.
Objectives: Evidences for anticoagulation strategies in cirrhotic with portal vein thrombosis (PVT) are still insufficient. This study aims to comprehensively compare the therapeutic effects of different therapeutic therapeutic measures in individuals suffering from cirrhosis with PVT, with the ultimate goal of providing evidence-based recommendations for thrombolytic therapy in this population.
Methods: Starting from 20 October 2023, a comprehensive search about therapeutic strategies for portal vein thrombosis in cirrhosis was conducted on PubMed, EMBASE, and Cochrane Library.
Fully Covered Stent-TIPS for Advanced HCC Patients with Portal Vein Tumor Thrombus-Related Severe Symptomatic Portal Hypertension.

Department of Interventional and Vascular Surgery, Peking University First Hospital, Beijing, People's Republic of China.
Purpose: Portal vein tumor thrombus (PVTT)-related severe symptomatic portal hypertension (SPH) leads to a poor prognosis in patients with advanced hepatocellular carcinoma (HCC). Traditional transjugular intrahepatic portosystemic shunt (TIPS) using covered plus bare stent can effectively relieve SPH, however, the bare segment is susceptible to obstruction due to PVTT invasion. This study aimed to evaluate the safety and efficacy of fully covered stent-TIPS (FCS-TIPS) for treatment of PVTT-related SPH in advanced HCC patients.
