Goals: To determine whether increased pulmonary artery pressure (PAP) following transjugular intrahepatic portosystemic shunting (TIPSS) results in short-term mortality or cardiorespiratory complications.
Background: TIPSS is frequently performed for complications of cirrhosis. PAP increases following TIPSS; however consequences of this phenomenon are unknown.
Study: Demographics, disease severity and etiology were recorded among patients undergoing TIPSS. PAP before and following TIPSS were measured and the relationship between PAP before and after TIPSS, and subsequent cardiorespiratory complications and mortality was examined.
Results: Thirty-one patients were enrolled (mean age 53 years, 74% men, 55% Child-Pugh class C cirrhosis). TIPSS was performed for variceal bleeding in 84% of cases. Ten patients (32%) died 5-20 days following TIPSS. PAP increased significantly following TIPSS (mean 20.8 mm Hg pre-TIPSS (95% CI 18.2-23.4) to 26.9 mm Hg post-TIPSS (95% CI 24.2-29.6, P = 0.0016). Congestive heart failure developed in 4 patients (13%), sepsis in 4 (13%), and ARDS in 8 (26%). Increased PAP following TIPSS was not associated with early mortality (P = 0.13), CHF (P = 0.31), or ARDS (P = 0.43). ARDS was the only significant predictor of short-term mortality following TIPSS (OR 18.7, P = 0.02 (95% CI: 1.5-232).
Conclusion: PAP increases after TIPSS and cardiorespiratory complications are common, yet unrelated to increased PAP. ARDS is independently associated with increased risk of mortality after TIPSS.

Transjugular intrahepatic portosystemic shunt (TIPS) is a widely used surgery for portal hypertension. In clinical practice, the diameter of the stent forming a shunt is usually selected empirically, which will influence the postoperative portal pressure. Clinical studies found that inappropriate portal pressure after TIPS is responsible for poor prognosis; however, there is no scheme to predict postoperative portal pressure.

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.

Background: Refractory ascites (RA) remains a serious complication in patients with cirrhosis. Currently, the insertion of a TIPS is considered the standard of care in these patients. To achieve symptom control in those with TIPS contraindications, tunneled peritoneal catheters (PeCa) or ascites pumps were introduced.

To investigate the association between overt hepatic encephalopathy (OHE) and liver pathology after transjugular intrahepatic portosystemic shunt (TIPS) creation in cirrhotic patients. From July 2015 to April 2024, 73 patients from 4 hospitals in China who received TIPS creation and liver biopsy were retrospectively enrolled in this study. Based on whether OHE occurred within 3 months after TIPS creation, the patients were categorized into OHE (n = 29) and non-OHE (n = 44) groups.

Portal hypertension is a hemodynamic abnormality that complicates the course of cirrhosis, as well as other diseases that affect the portal venous circulation. The development of portal hypertension compromises prognosis, especially when it rises above a certain threshold known as clinically significant portal hypertension (CSPH). In the consensus conference on Portal Hypertension promoted by the Spanish Association for the Study of the Liver and the Hepatic and Digestive diseases area of the Biomedical Research Networking Center (CIBERehd), different aspects of the diagnosis and treatment of portal hypertension caused by cirrhosis or other diseases were discussed.
