Objective To explore the feasibility of using ultrasound to evaluate stent placement for managing graft stenosis after Meso-rex bypass for cavernous transformation of the portal vein in adults. Methods This study enrolled the patients who underwent Meso-rex bypass due to cavernous transformation of the portal vein,were diagnosed graft stenosis by postoperative ultrasound,and then underwent percutaneous portal vein puncture portography and stent placement.We then compared the ultrasonic measurement indicators and sonographic manifestations before and after stent placement,and evaluated the alleviation of portal hypertension symptoms after stent placement and related clinical indexes. Results Finally,8 patients were enrolled in this study,including 5 males and 3 females,with an average age of(32.4±14.7)years.The median duration of follow-up was 26 months after stent placement.The mean diameter of graft stenosis was(2.74±0.23)mm after Meso-rex bypass and became wider[(7.23±0.68)mm]after stent placement(

Hepatic hydrothorax is a transudative pleural effusion that complicates advanced liver cirrhosis. Patients refractory to medical treatment plus salt restriction and diuretics are considered to have refractory hepatic hydrothorax and may require transjugular intrahepatic portosystemic shunt (TIPS) or liver transplant. Successful antiviral therapy reduces the incidence of some complications of cirrhosis secondary to HCV infection. We report a case of hepatic hydrothorax in a 55-year-old female patient with HCV cirrhosis, which exhibited a spontaneous decrease in pleural effusion after direct antiviral agent (DAA) therapy. In cases of HCV cirrhosis, DAAs are worth administering before treatment by TIPS or liver transplantation.

Two dogs presented with vomiting and head pressing. In both dogs, a large vessel was revealed in computed tomography (CT) angiography, which was found to leave the portal vein (PV) cranial to the splenomesenteric confluence and enter the pre-hepatic caudal vena cava cranial to the right renal vein. The flow of portal blood to the liver was not identified. Based on CT angiography, the dogs were suspected to have congenital PV aplasia with portocaval shunting. Diagnostic imaging of potential malformations for PV continuation should be conducted before attempting shunt closure.

This study aimed to report three new cases of an association between two rare conditions, congenital portosystemic shunts (CPSS) and trimethylaminuria (TMAU), and the efficacy of endovascular closure of the CPSS for resolving TMAU. Between November 2014 and April 2017, 15 patients with CPSS were enrolled in this prospective study to assess the efficacy of percutaneous endovascular shunt closure. Three patients presented with clinical symptoms of TMAU that were confirmed by urine analysis of trimethylamine (TMA) and TMA n-oxide. One year after endovascular closure of the congenital portosystemic shunt, the same parameters were evaluated were obtained and the values were compared to the pretreatment values. The results indicated the disappearance of clinical symptoms of TMAU and normalization of the urine test parameters in two patients and no changes in one patient, who developed new portosystemic communications.

BACKGROUND/AIMS: In recent years, greater assessment accuracy after transjugular intrahepatic portosystemic shunt (TIPS) to ascertain prognosis has become important in decompensated cirrhosis due to portal hypertension. The aim of this study was to assess the ratio of the portal pressure gradient (PPG) pre-TIPS (pre-PPG) to albumin (PPA), which influence ascites formation in cirrhotic patients in the 6-months after TIPS placement, and is a metric introduced in our study. METHODS: This was a retrospective cohort study of 58 patients with decompensated cirrhosis admitted to an academic hospital for the purpose of TIPS placement. We collected the following data: demographics, laboratory measures, and PPG during the TIPS procedure. Then we analyzed the association between the above data and ascites formation post-TIPS in cirrhosis patients. RESULTS: Twenty-two patients with ascites and 28 without ascites were evaluated. Univariate and binary logistic regression analysis were adjusted for the following variables: to determine prognosis; Child-Pugh scores, lymphocyte count, platelet count, hemoglobin level, albumin level and pre-PPG or PPA. The outcome showed that PPA was better than pre-PPG and albumin for predicting ascites according to area under receiver operating characteristic curves and a statistical model that also showed PPA’s influence 6-months post-TIPS. CONCLUSIONS: The combined measurement of pre-PPG and albumin, defined as PPA, may provide a better way to predict post-TIPS ascites in decompensated cirrhosis, which underlines the need for a large clinical trial in the future.

Acute gastroesophageal variceal hemorrhage is a dreaded complication in patients with liver cirrhosis. Endoscopic therapy and radiologic intervention for gastroesophageal bleeding have rapidly developed in the recent decades. Endoscopic treatment is initially performed to stop variceal hemorrhage. For the treatment of esophageal variceal bleeding, endoscopic variceal ligation (EVL) is considered the endoscopic treatment of choice. In cases of gastric variceal hemorrhage, the type of gastric varices (GVs) is important in deciding the strategy of endoscopic treatment. Endoscopic variceal obturation (EVO) is recommended for fundal variceal bleeding. For the management of gastroesophageal varix type 1 bleeding, both EVO and EVL are available treatment options; however, EVO is preferred over EVL. If endoscopic management fails to control variceal hemorrhage, radiologic interventional modalities could be considered. Transjugular intrahepatic portosystemic shunt is a good option for rescue treatment in refractory variceal bleeding. In cases of refractory hemorrhage of GVs in patients with a gastrorenal shunt, balloon-occluded retrograde transvenous obliteration could be considered as a salvage treatment.

BACKGROUND: To evaluate the safety and efficacy of transjugular intrahepatic portosystemic shunt (TIPS) creation for the management of portal hypertension in patients with hepatocellular carcinoma (HCC). METHODS: A literature search of the MEDLINE/PubMed and Embase databases was conducted. All articles reporting the outcomes of TIPS creation for variceal bleeding and refractory ascites and hepatic hydrothorax in patients with HCC were included. Exclusion criteria were non-English language, sample size < 5, data not extractable, and data reported in another article. RESULTS: A total of 280 patients (mean age, 48–58; male gender, 66%) from five articles were included. TIPS creation was performed for variceal bleeding in 79% and refractory ascites and/or hepatic hydrothorax in 26% of patients. Technical and clinical success was achieved in 99% and 64% of patients, respectively. Clinical failure occurred in 36% of patients due to rebleeding or recurrent bleeding (n = 77) or no resolution or improvement of refractory ascites and hepatic hydrothorax (n = 24). One percent of patient had major complications, including accelerated liver failure (n = 1) and multi-organ failure resulting from hemorrhagic shock (n = 1), all of which resulted in early (i.e., within 30 days) death. Hepatic encephalopathy occurred in 40% of patients after TIPS creation. Lung metastasis was found 1% of patient 5 months (n = 1) and 72 months (n = 1) after TIPS creation. CONCLUSION: TIPS creation seems to be safe and effective for the management of portal hypertension in patients with HCC.

A 2-year-old, spayed female, Korean domestic short-hair cat was presented with depression and vomiting. The patient had history of weight loss lasting seven months. Physical examination revealed icterus in the pinna, oral mucosa, and sclera. Based on ultrasonography and computed tomography, tentative diagnosis was extrahepatic biliary tract obstruction with acquired portosystemic shunt (PSS). Tumor or inflammation of hepatobiliary system was suspected as the cause of obstruction of the common bile duct. But it could not be determined without biopsy. The severely dilated cystic duct was considered to cause portal hypertension and secondary multiple PSS. The patient expired without histopathologic examination.
