Efficacy evaluation of novel oral anticoagulants in patients with cirrhosis accompanied with portal vein thrombosis: a meta-analysis / 中华肝脏病杂志

Objective: To analyze the safety and efficacy of using novel oral anticoagulants (rivaroxaban and others) in patients with cirrhosis accompanied with portal vein thrombosis (PVT). Methods: Clinical research literature published from the establishment of the database to June 20, 2021, was retrieved from PubMed, Web of Science, CNKI, Wanfang, and Weipu databases by combining subject terms and free words. RevMan software was used for the random group meta-analysis model. Results: In terms of PVT recanalization, the novel oral anticoagulants (such as low molecular weight heparin and others) had a higher recanalization rate than traditional anticoagulants (OR = 13.75, 95%CI 3.58-52.9, P = 0.000 1). In terms of bleeding, the novel oral anticoagulants did not increase the risk of bleeding compared with traditional anticoagulants (OR = 2.42, 95%CI 0.62-9.41, P = 0.20). Conclusion: The novel oral anticoagulant drugs are superior to traditional anticoagulants in terms of the occurrence of PVT recanalization; however, there is no statistically significant difference in terms of the occurrence of bleeding between the two groups.

Diagnostic value of contrast-enhanced ultrasound in hepatic epithelioid hemangioendothelioma / 中华肝脏病杂志

Objective: To investigate the features of contrast-enhanced ultrasound (CEUS) in hepatic epithelioid hemangioendothelioma (HEHE) in order to improve the preoperative diagnosis rate. Methods: CEUS images of 32 pathologically-proven cases of hepatic epithelioid hemangioendothelioma from January 2004 to August 2021 were collected. Lesions were analyzed to observe the features of enhancement mode, enhancement intensity, and distinct enhancement phases. Results: Among the 32 cases, one had a solitary lesion, 29 had multiple lesions, and two had diffuse-type lesions. Contrast-enhanced ultrasound revealed a total of 42 lesions in 32 cases. In terms of arterial phase enhancement, 18 lesions had overall enhancement, six lesions had uneven dendritic enhancement, 16 lesions had rim-like enhancement, and two lesions had just slight peripheral spot enhancement around the lesions. Among the three cases, there were multiple lesions that had overall enhancement and ring enhancement. In terms of the enhancement phase, 20 lesions showed "fast progression", 20 lesions showed "same progression", and two lesions showed "slow progression". During the late arterial or early portal venous phases with rapid washout, all lesions manifested as hypoechoic. With peaked enhanced intensity, 11 lesions had a lower enhancement intensity than the surrounding normal liver parenchyma; 11 lesions had the same enhancement degree as the surrounding normal liver parenchyma; and 20 lesions had a higher enhancement degree than the surrounding normal liver parenchyma. All 16 ring-enhancing lesions had marked hyperenhancement. In the typical enhancing lesions, four showed hyperenhancement, five showed low enhancement, and nine showed isoenhancement. In the dendrite-enhancing lesions, there were two isoenhancing and four hypoenhancing. Contrast-enhanced ultrasound delineated the boundaries of all lesions more clearly than two-dimensional ultrasound. Conclusion: Contrast-enhanced ultrasound has certain value in the diagnosis of hepatic epithelioid hemangioendothelioma.

Trombose de veia porta não associada à cirrose - desafio terapêutico / Non-cirrhotic portal vein thrombosis - therapeutic challenge

Resumo A trombose de veia porta (TVP) é uma doença na qual ocorre trombose desde os ramos intra-hepáticos da veia porta, podendo se estender até a veia esplênica e/ou veia mesentérica superior, estando associada, na maioria das vezes, à cirrose hepática. A TVP não associada a cirrose é rara. O objetivo deste artigo foi relatar dois casos de TVP não associados à cirrose, que foram tratados com anticoagulação e tiveram evolução clínica satisfatória.

Abstract Portal vein thrombosis (PVT) is a disease in which thrombosis occurs from the intrahepatic branches of the portal vein, and may extend to the splenic vein and/or superior mesenteric vein. It is most often associated with liver cirrhosis. PVT not associated with cirrhosis is rare. The aim of this article is to report two cases of PVT in which it was not associated with cirrhosis. Both were treated with anticoagulation and clinical progress afterwards was good.

Hepatic manifestations of hematological diseases / 中华肝脏病杂志

Liver involvement is often observed in hematological disorders, resulting in liver abnormality, including unconjugated hyperbilirubinemia, monoclonal hyperglobulinemia, portal vein, or hepatic vein thrombosis or portal hypertension, hepatosplenomegaly, or iron accumulation in the liver. Here we summarize the major hematological diseases that often affect the liver: hemolytic anemia, defect in coagulation or anti-coagulation factors, myeloproliferative neoplasm, hemophagocytic lymphohistiocytosis, multiple myeloma, leukemia, and lymphoma. We hope this review will help clinicians diagnose and manage the patients with liver involvement by hematological disorders.

Paying attention to other systemic diseases of hepatic manifestations: a return to common sense in clinical practice / 中华肝脏病杂志

Liver have complex functions with a high workload. Various liver diseases are the result of the interaction of diverse genetic and environmental factors. Moreover, other systemic diseases may also affect liver, producing corresponding manifestations, such as abnormal liver function tests, portal vein or hepatic vein thrombosis, portal hypertension, hepatosplenomegaly and liver space-occupying lesions. Therefore, it is extremely important for hepatologists to have an in-depth understanding of other systemic diseases of hepatic manifestations, especially hematologic, connective tissue, endocrine, and circulatory, in order to improve the level of clinical diagnosis and treatment.

Aneurisma de la vena porta. A propósito de un caso / Portal vein aneurysm. A case presentation

RESUMEN Fundamento: los aneurismas de la vena porta son entidades poco frecuentes, representan aproximadamente el 3% de los aneurismas del sistema venoso. La mayoría de los aneurismas de la vena porta se detectan en pacientes con hígado sano, aunque en algunas ocasiones la hipertensión portal podría favorecer el desarrollo de la patología. Los lugares más comunes son la confluencia venosa esplenomesentérica, la vena porta principal y las ramas de la vena porta intrahepática en los sitios de bifurcación. Objetivo: presentar el caso de un paciente portador de una aneurisma de la vena porta. Presentación del Caso: Paciente femenina, blanca de 49 años de edad con antecedentes de trastornos dispépticos, y en ocasiones, dolor a nivel del hipocondrio derecho. Su examen físico era negativo y la impresión diagnóstica de su médico de asistencia era litiasis vesicular. Durante la realización del examen ultrasonográfico se encuentra como dato positivo una dilatación de tipo aneurismático de la vena porta en el inicio de su trayecto intrahepático de 18 mm de diámetro, y el resto del examen resultó negativo. Conclusiones: Por lo inusual de este caso se decide hacer su presentación.

ABSTRACT: portal vein aneurysms are uncommon, representing approximately the 3% of venous system aneurysms. Most portal vein aneurysms are detected in patients with healthy liver, although on some occasions portal hypertension could favor their development. The most common sites are the splenomesenteric venous confluence, the main portal vein and the branches of the intrahepatic portal vein at bifurcation sites. Objective: to present the case of a patient with a portal vein aneurysm. Case Presentation: A 49-years-old white female patient with a history of dyspeptic disorders, and sometimes pain in the right upper quadrant. Her physical examination was negative and the diagnostic impression from her attending physician was gallstones. During the ultrasound examination, an aneurysmal dilatation of the portal vein at the beginning of its intrahepatic path of 18 mm in diameter was found as a positive finding, being the rest of the examination negative Conclusions: Due to the unusual nature of this case, it was decided to present it.

The aim of this study was to analyse a patient dignosed in our hospital as having pylephlebitis. The patient is a 29 years old male, and we must consider that pylophlebitis refers to the septic thrombosis of the portal venous system, associated to some kind of infectious process. Can occur related to acute appendicitis, colonic diverticulitis and cholangitis, among others. Is a rare but close to a significant morbidity and mortality, since it can develop to an abdominal sepsis. The management review of the case reported, is presented (AU)

Intravascular and intraparenchymatous hepatic segmentary sclerosis

Abstract Purpose: To evaluate the morphological effects of injected sclerosing agents into the liver. Methods: This study was performed on twenty dogs, distributed into five groups: Group 1 (n = 5) - control, Group 2 (n = 5) - injection of 50% glucose solution inside hepatic parenchyma and animals followed during seven days, Group 3 (n = 10) - injection of ethanol inside hepatic parenchyma and animals distribution into two subgroups Subgroup 3A (n = 5) - followed during 24 hours and subgroup 3B (n = 5) - followed during seven days (group 3B), Group 4 (n = 5) - ethanol injection inside left portal vein branch and followed during 24 hours. Livers were macroscopically evaluated, submitted to hepatic arteriography and portography, then histology. Results: All animals in Group 4 died within 23 hours due to diffuse hepatic necrosis. The animals of groups 2 and 3 had a satisfactory evolution. Fibrosis formed in the segment reached by the sclerosant solution and interruption of the contrast flow injected into the portal system. Conclusion: Intrahepatic parenchymal ethanol injection is well tolerated and causes sclerosis restricted to a specific segment; however, intraportal ethanol injection causes massive hepatic necrosis and can lead to death.

Mesocaval Shunt Creation for Jejunal Variceal Bleeding with Chronic Portal Vein Thrombosis

The creation of transjugular intrahepatic portosystemic shunt (TIPS) is a widely performed technique to relieve portal hypertension, and to manage recurrent variceal bleeding and refractory ascites in patients where medical and/or endoscopic treatments have failed. However, portosystemic shunt creation can be challenging in the presence of chronic portal vein occlusion. In this case report, we describe a minimally invasive endovascular mesocaval shunt creation with transsplenic approach for the management of recurrent variceal bleeding in a portal hypertension patient with intra- and extrahepatic portal vein occlusion.

Management and conduct of vascular diseases of the portal system / Manejo e conduta das doenças vasculares do sistema porta

Aneurysms and thromboses of the portal vein are rare pathologies of the portal system that commonly follow an asymptomatic course. The vast majority of cases are diagnosed as incidental findings during imaging studies. Symptoms of aneurysms are the result of mass effects, while thrombosis symptoms are a function of the liver's ability to form a collateral circulation network in the thrombosis. The scant experience with such cases poses a dilemma for patient management and so the vast majority of authors choose an expectant approach with rigorous patient surveillance and only intervene in symptomatic patients. We report one case of an aneurysm of the portal vein and one case of portal vein thrombosis and discuss management and observation of these patients...

O aneurisma e a trombose de veia porta são doenças raras do sistema porta, que comumente cursam sem sintomas. A grande maioria dos pacientes é diagnosticada com achados em exames de imagem. Os sintomas são atribuídos ao efeito de massa, no caso do aneurisma, e relativos à capacidade hepática de formar uma rede de circulação colateral, no caso da trombose. A escassa experiência nesses casos representa um dilema na abordagem desses pacientes e, portanto, a grande maioria dos autores opta por seguimento rigoroso e a intervenção é indicada apenas para os pacientes sintomáticos. Neste trabalho, relatamos um caso de aneurisma de veia porta e outro de trombose da veia porta, propondo o manejo e o acompanhamento desses pacientes...

Preoperative Estimation of Future Remnant Liver Function Following Portal Vein Embolization Using Relative Enhancement on Gadoxetic Acid Disodium-Enhanced Magnetic Resonance Imaging

OBJECTIVE: To retrospectively evaluate relative enhancement (RE) in the hepatobiliary phase of gadoxetic acid disodium-enhanced magnetic resonance (MR) imaging as a preoperative estimation of future remnant liver (FRL) function in a patients who underwent portal vein embolization (PVE). MATERIALS AND METHODS: In 53 patients, the correlation between the indocyanine green clearance (ICG-K) and RE imaging was analyzed before hepatectomy (first analysis). Twenty-three of the 53 patients underwent PVE followed by a repeat RE imaging and ICG test before an extended hepatectomy and their results were further analyzed (second analysis). Whole liver function and FRL function were calculated on the MR imaging as follows: RE x total liver volume (RE Index) and FRL-RE x FRL volume (Rem RE Index), respectively. Regarding clinical outcome, posthepatectomy liver failure (PHLF) was evaluated in patients undergoing PVE. RESULTS: Indocyanine green clearance correlated with the RE Index (r = 0.365, p = 0.007), and ICG-K of FRL (ICG-Krem) strongly correlated with the Rem RE Index (r = 0.738, p < 0.001) in the first analysis. Both the ICG-Krem and the Rem RE Index were significantly correlated after PVE (r = 0.508, p = 0.013) at the second analysis. The rate of improvement of the Rem RE Index from before PVE to after PVE was significantly higher than that of ICG-Krem (p = 0.014). Patients with PHLF had a significantly lower Rem RE Index than patients without PHLF (p = 0.023). CONCLUSION: Relative enhancement imaging can be used to estimate FRL function after PVE.

Percutaneous Unilateral Biliary Metallic Stent Placement in Patients with Malignant Obstruction of the Biliary Hila and Contralateral Portal Vein Steno-Occlusion

OBJECTIVE: To investigate the outcomes of percutaneous unilateral metallic stent placement in patients with a malignant obstruction of the biliary hila and a contralateral portal vein steno-occlusion. MATERIALS AND METHODS: Sixty patients with a malignant hilar obstruction and unilobar portal vein steno-occlusion caused by tumor invasion or preoperative portal vein embolization were enrolled in this retrospective study from October 2010 to October 2013. All patients were treated with percutaneous placement of a biliary metallic stent, including expanded polytetrafluoroethylene (ePTFE)-covered stents in 27 patients and uncovered stents in 33 patients. RESULTS: A total of 70 stents were successfully placed in 60 patients. Procedural-related minor complications, including self-limiting hemobilia (n = 2) and cholangitis (n = 4) occurred in six (10%) patients. Acute cholecystitis occurred in two patients. Successful internal drainage was achieved in 54 (90%) of the 60 patients. According to a Kaplan-Meier analysis, median survival time was 210 days (95% confidence interval [CI], 135-284 days), and median stent patency time was 133 days (95% CI, 94-171 days). No significant difference in stent patency was observed between covered and uncovered stents (p = 0.646). Stent dysfunction occurred in 16 (29.6%) of 54 patients after a mean of 159 days (range, 65-321 days). CONCLUSION: Unilateral placement of ePTFE-covered and uncovered stents in the hepatic lobe with a patent portal vein is a safe and effective method for palliative treatment of patients with a contralateral portal vein steno-occlusion caused by an advanced hilar malignancy or portal vein embolization. No significant difference in stent patency was detected between covered and uncovered metallic stents.

Hepatoportal Sclerosis in Childhood: Descriptive Analysis of 12 Patients

Hepatoportal sclerosis (HPS) is defined as sclerosis of portal areas in the absence of cirrhosis. There is little information about HPS in children in the literature. The aim of this study was to describe the clinical presentation, associated disorders, laboratory characteristics and outcome of children who were diagnosed as HPS. This study included 12 children diagnosed as HPS by the Pathology Department between 2005 and 2011. Data were collected from the gastroenterology clinic charts retrospectively, including demographics, presentation characteristics, laboratory data and recent status of patients. Twelve patients were enrolled (6 girls, 6 boys). The median age of patients was 13.5 yr. Median age at the time of biopsy was 11 yr. Four patients had splenomegaly, 3 had esophageal varices, one had hepatopulmonary syndrome and had been transplanted. Smooth muscle antibody was found positive in 4 patients, without autoimmune hepatitis findings in liver biopsy. One patient had celiac disease and another patient had positive celiac disease serology but pathology findings. Another patient had Turner's syndrome. Mean follow-up time was 39 months (3.3 yr) after biopsy. Hepatoportal sclerosis does not necessarily present with portal hypertension in children.

Practical Effect of Sorafenib Monotherapy on Advanced Hepatocellular Carcinoma and Portal Vein Tumor Thrombosis

BACKGROUND/AIMS: We investigated the effects of sorafenib monotherapy on advanced hepatocellular carcinoma (HCC) and portal vein tumor thrombosis (PVTT) in a clinical setting. METHODS: In total, 143 consecutive patients with unresectable HCC were treated with sorafenib. Among these patients, 30 patients with advanced HCC and PVTT (Vp3 or 4) were treated with sorafenib monotherapy. RESULTS: All patients had a performance status of 1 to 2 (Eastern Cooperative Oncology Group 1/2, 20/10) and Child-Pugh class A or B (A/B, 17/13). Eleven patients had modified Union for International Cancer Control stage IVA tumors, whereas 19 had stage IVB tumors. All patients had PVTT (Vp3, 6; Vp4, 24). Following sorafenib monotherapy, three patients (10.0%) had a partial response with PVTT revascularization, and nine (30.0%) had stable disease, with a disease control rate of 33.3%. The median overall survival was 3.1 months (95% confidence interval [CI], 2.70 to 3.50), and the median progression-free survival was 2.0 months (95% CI, 1.96 to 2.05). Fatigue and hand-foot skin reactions were the most troublesome side effects. CONCLUSIONS: A limited proportion of patients with advanced HCC and PVTT exhibited a remarkable outcome after sorafenib monotherapy, although the treatment results in this type of patient is extremely poor. Further studies to predict good responders to personalized therapy are warranted.

Validity of color doppler sonography in evaluation of malignant portal vein thrombosis in hepatocellular carcinoma

The objective of this study was to assess the validity of color doppler sonography in the evaluation of malignant portal vein thrombosis in hepatocellular carcinoma [findings on biphasic spiral computed tomography were used as the gold standard]. This study was conducted in the Department of Diagnostic and Interventional Radiology at Shifa International Hospital, Islamabad from March 2009 to November 2009. A total of 100 patients those who were already diagnosed cases of HCC or those having high suspicion of HCC based on clinical criteria [e.g., chronic hepatitis B or C, liver cirrhosis, increased alpha fetoprotein level [>400ng/dl]] and /or Imaging findings [e.g., sonography, MRI, CT] were included in this study. Color doppler sonography had 80.7% sensitivity and 100% specificity in the detection of arterial flow in the portal vein thrombus [i.e., malignant thrombus] in comparison with biphasic CT [taken as gold standard]. Color doppler sonography is an effective, noninvasive method for evaluating the presence of malignant portal vein thrombosis associated with HCC

The diameter of the originating vein determines esophageal and gastric fundic varices in portal hypertension secondary to posthepatitic cirrhosis

OBJECTIVE: The aim of this study was to determine whether and how the diameter of the vein that gives rise to the inflowing vein of the esophageal and gastric fundic varices secondary to posthepatitic cirrhosis, as measured with multidetector-row computed tomography, could predict the varices and their patterns. METHODS: A total of 106 patients with posthepatitic cirrhosis underwent multidetector-row computed tomography. Patients with and without esophageal and gastric fundic varices were enrolled in Group 1 and Group 2, respectively. Group 1 was composed of Subgroup A, consisting of patients with varices, and Subgroup B consisted of patients with varices in combination with portal vein-inferior vena cava shunts. The diameters of the originating veins of veins entering the varices were reviewed and statistically analyzed. RESULTS: The originating veins were the portal vein in 8% (6/75) of patients, the splenic vein in 65.3% (49/75) of patients, and both the portal and splenic veins in 26.7% (20/75) of patients. The splenic vein diameter in Group 1 was larger than that in Group 2, whereas no differences in portal vein diameters were found between groups. In Group 1, the splenic vein diameter in Subgroup A was larger than that in Subgroup B. A cut-off splenic vein diameter of 8.5 mm achieved a sensitivity of 83.3% and specificity of 58.1% for predicting the varices. For discrimination of the varices in combination with and without portal vein-inferior vena cava shunts, a cut-off diameter of 9.5 mm achieved a sensitivity of 66.7% and specificity of 60.0%. CONCLUSION: The diameter of the splenic vein can be used to predict esophageal and gastric fundic varices and their patterns.

Ascitis quilosa y trombosis de la vena porta en paciente con cirrosis hepática criptogénica / Ascites chylosus and thrombosis of portal vein in a patient with cryptogenic hepatic cirrhosis

Se presentó un paciente de 73 años de edad, de raza blanca, con ascitis quilosa, acompañada de insuficiencia hepática e hipertensión portal. Se evidenció la presencia de trombosis de la vena porta y varices esofágicas. Se notifica por lo infrecuente de la aparición de ascitis quilosa en pacientes con cirrosis hepática y su posible asociación con trombosis de la vena porta

This is the case of a white patient aged 73 presenting with chylosus ascites and liver failure and portal hypertension. It was evidenced la presence of thrombosis of portal vein and esophageal varices. It is noteworthy the non-frequent of chylosus ascites in patients presenting with liver cirrhosis and its possible association with a portal vein thrombosis

Liver pathology in collagen vascular disorders highlighting the vascular changes within portal tracts.

Background: Collagen vascular disorders (CVDs) are autoimmune disorders with multisystem involvement. Clinical liver involvement is not a characteristic feature though histological involvement could be frequent. Liver disease in CVDs could be the consequence of various factors. Aim: The aim was to analyze the histological spectrum of liver in collagen vascular disorders (CVDs) at autopsy. Materials and Methods: Thirty-six autopsy livers negative for hepatitis B or C virus were studied in CVD cases with no known association with chronic liver disease or vascular thrombosis or hematological disorder. Cirrhotic and normal livers were used as controls. The paired t-test, one-way ANOVA, and two-sided Dunnett t-test were used for comparison (< 0.05). None of the control cases showed any abnormal vessels. Results: There were 21 systemic lupus erythematosus (SLE), 7 rheumatoid arthritis (RA), 5 systemic sclerosis (SSc), and 3 polyarteritis nodosa (PAN) cases (M:F = 11:25, age range 23-60 years). Histology: Diffuse nodular regenerative hyperplasia of liver (NRHL) was seen in 10 cases, and 6 (5 SLE and 1 RA) had numerous abnormal thin-walled vessels in intermediate- and small-sized portal tracts with no vascular occlusion or inflammation. Moderate sized portal tracts showed more interface and lobular inflammation. The main portal vein and its major branches were normal. None of these six cases had increased transmainases (P>0.05). Most SLE cases had increased transaminases (P<0.05). No evidence of portal hypertension was seen in all except in one RA. Septicemia is known to be associated with raised transaminases. Conclusion: A rare pathology of conglomerate of abnormal vessels in intermediate- and small-sized portal system was observed co-existing with NRHL in CVDs. Raised liver enzyme with interface hepatitis in CVD may not necessarily warrant an overlap, as a similar feature could be observed in septicemia.

Prediction of large esophageal varices in cirrhotic patients using classification and regression tree analysis

OBJECTIVES: Recent guidelines recommend that all cirrhotic patients should undergo endoscopic screening for esophageal varices. That identifying cirrhotic patients with esophageal varices by noninvasive predictors would allow for the restriction of the performance of endoscopy to patients with a high risk of having varices. This study aimed to develop a decision model based on classification and regression tree analysis for the prediction of large esophageal varices in cirrhotic patients. METHODS: 309 cirrhotic patients (training sample, 187 patients; test sample 122 patients) were included. Within the training sample, the classification and regression tree analysis was used to identify predictors and prediction model of large esophageal varices. The prediction model was then further evaluated in the test sample and different Child-Pugh classes. RESULTS: The prevalence of large esophageal varices in cirrhotic patients was 50.8 percent. A tree model that was consisted of spleen width, portal vein diameter and prothrombin time was developed by classification and regression tree analysis achieved a diagnostic accuracy of 84 percent for prediction of large esophageal varices. When reconstructed into two groups, the rate of varices was 83.2 percent for high-risk group and 15.2 percent for low-risk group. Accuracy of the tree model was maintained in the test sample and different Child-Pugh classes. CONCLUSIONS: A decision tree model that consists of spleen width, portal vein diameter and prothrombin time may be useful for prediction of large esophageal varices in cirrhotic patients.
