Acute variceal bleeding in cirrhosis represents a critical clinical event that significantly impacts patient prognosis, with mortality rates increasing further after a second episode. This underscores the need for immediate intervention and optimal prophylaxis. The creation of a transjugular intrahepatic portosystemic shunt (TIPS) has been proven to be highly effective for managing esophageal variceal bleeding. However, the use of TIPS for managing cardiofundal gastric varices and ectopic varices remains debated due to their unique vascular anatomy and the limited data available. These varices, although less prevalent than esophageal varices, are complex and heterogeneous vascular shunts between the splanchnic venous system and the systemic veins. Indeed, while endoscopic therapy with tissue adhesives is widely endorsed for achieving hemostasis in active hemorrhage, there is no consensus regarding the optimal approach for secondary prophylaxis. Recent research emphasizes the efficacy of endovascular techniques over endoscopic treatments, such as TIPS and endovascular variceal embolization techniques. This review examines the use of TIPS in managing acute variceal bleeding in patients with cirrhosis, focusing specifically on cardiofundal gastric varices and ectopic varices, discussing optimal patient care based on the latest evidence, aiming to improve outcomes for this challenging subset of patients.

Background and Aims: Bacterial infections are associated with high mortality rates in patients with decompensated cirrhosis. Early diagnosis with the available diagnostic tools is challenging. Metabolomics is a novel technique with a widespread application in hepatology. The aims of our study were to find new biomarkers for decompensated cirrhosis and for those with overlapping bacterial infections. Methods: 43 patients with compensated and 54 patients with decompensated cirrhosis were enrolled in the study. In patients with decompensation, a complete infectious workup was performed at admission. Blood and ascitic fluid were collected and stored at -80° C until performing the metabolomic analysis. Statistical analysis was performed using the Metaboanalyst 4.0 software. Results: 36 patients (66%) in the decompensated group were infected. Among them, 15 had multiple infections; thus, finally, 52 infections were diagnosed. The main metabolic pathways affected in patients with decompensated cirrhosis were those related to lipid metabolism, involving acylcarnitines, stearic acid derivatives, and 12/15 HETE-GABA. N-oleoyl ethanolamine was the most promising biomarker for bacterial infection diagnosis. Moreover, prostaglandin E2/D2/H2 and N-oleoyl alanine levels were higher in Gram- positive infections and ceramides (d16:2/18:0), in Gram-negative infections, respectively. L-phenylalanine (m/z=166.09) and lysophosphatidylethanolamine (18:3/0:0) were the two most relevant identified ascitic biomarkers for spontaneous bacterial peritonitis diagnosis. Conclusions: The lipid and energetic metabolic pathways were the most affected in patients with decompensated cirrhosis and those with overlapping infections.

This report describes the use of local thrombolysis using a tissue plasminogen activator in a case of a patient with refractory ascites referred for transjugular intrahepatic portosystemic shunt (TIPS) insertion. After successful TIPS insertion, the patient developed acute extended portal vein and TIPS thrombosis, which were treated with local thrombolysis using a tissue plasminogen activator, followed by the complete resolution of ascites. Although there are only limited published data of local thrombolysis for acute splanchnic vein thrombosis, we also review the relevance of the problem in the context of advanced liver disease.
