Hepatic Lesions of A Standard Poodle Dog with Intrahepatic Portosystemic Shunt

Aims: This study aimed at assessing the risk factors for hepatic encephalopathy (HE) after transjugular intrahepatic portosystemic shunt (TIPS) in patients with hepatocellular carcinoma (HCC) and portal hypertension. Method: Consecutive patients (n=279) with primary HCC who underwent TIPS between January 1997 and March 2012 at a single institution were retrospectively reviewed. Patients were followed up for 2 years. Pre-TIPS, peri-TIPS and post-TIPS clinical variables were reviewed using univariate and multivariate analyses to identify risk factors for HE after TIPS. Results: The overall incidence of HE was 41% (114/279). Multivariate analysis showed an increased odds for HE in patients with: >3 treatments with transcatheter arterial chemoembolization (TACE) and/or trans-arterial embolization (TAE) (odds ratio [OR], 4.078; 95% confidence interval [95%CI], 1.748-9.515); hepatopetal portal flow (OR, 2.362; 95%CI, 1.032-5.404); high portosystemic pressure gradient (OR, 1.198; 95%CI, 1.073-1.336) and high pre-TIPS MELD score (OR, 1.693; 95%CI, 1.390-2.062). Odds for HE were increased 1.693 fold for each 1-point increase in the MELD score, and 1.198 fold for each 1-mmHg decrease in the post-TIPS portosystemic pressure gradient. Conclusion: The identification of clinical variables associated with increased odds of HE may be useful for the selection of appropriate candidates for TIPS. Results suggest that an inappropriate decrease in the portosystemic pressure gradient might be associated with HE after TIPS. In addition, >3 treatments with TACE/TAE, hepatopetal portal flow, and high MELD score were also associated with increased odds of HE after TIPS. Key words: – – – .

End Stage

Isolated gastric varices are far less prevalent in Western countries where the rate of splenic thrombosis is much lower. However, in Asian countries the entity is more common and therefore a more robust treatment approach has been developed. Balloon-occlusive retrograde transvenous obliteration (BRTO) was first described in 1984 and then revived in 1996. The procedure, while uncommon in the U.S. and not recognized by the AASLD practice guidelines, allows for direct exclusion from the portosystemic system. Here we describe the case of a patient with alcoholic cirrhosis decompensated by bleeding gastric varices treated with BRTO. Abbrevations: BRTO: balloon-occlusive retrograde transverse obliteration; EGD: esophagogastro-duodenoscopy; HE: hepatic encephalopathy; MELD: Model for End Stage Liver Disease; TIPS: transjugular intrahepatic portosystemic shunt.
