TIPS en pacientes cirróticos con trombosis venosa portal: una revisión de la literatura / TIPS in cirrhotic patients with portal vein thrombosis: A review of the literature

En los últimos años, la trombosis de la vena porta entre los pacientes cirróticos se ha comportado como una entidad reconocida y cada vez más estudiada, no solo por su creciente incidencia, sino por la asociación con gravedad y mal pronóstico en cirrosis. Asimismo, se hacen objeto de estudio las terapias disponibles para el manejo tanto médico como quirúrgico de estos pacientes, lo que ha dado un papel importante a la derivación portosistémica transyugular intrahepática (TIPS). El uso de TIPS en esta población se posiciona como una alternativa de manejo aceptable, no solo por brindar mejoría en las complicaciones derivadas de la hipertensión portal, sino también por sus resultados prometedores en diferentes estudios sobre el flujo y la recanalización portal, y por su perfil de seguridad. Sin embargo, la eficacia, los efectos adversos a largo plazo y el pronóstico de dicha intervención en la compleja fisiopatología de la cirrosis deben continuar en estudio. El objetivo de este artículo es revisar los avances del uso de TIPS en el manejo de pacientes con cirrosis hepática y trombosis portal.

In recent years, portal vein thrombosis among cirrhotic patients has been a well-recognized and continuously studied entity, not only because of its increasing incidence but also because of its association with severity and poor prognosis in cirrhosis. Likewise, therapies available for both medical and surgical management in these patients are being studied, which has given an important role to the transjugular intrahepatic portosystemic shunt (TIPS). The use of TIPS in this population is positioned as an acceptable management alternative, not only because it provides improvement in complications derived from portal hypertension, but also because of its promising results in different studies on portal flow and recanalization upgrade, and for its safety. However, the efficacy, long-term adverse effects, and prognosis of this intervention in the complex pathophysiology of cirrhosis must continue to be studied. The objective of this article is to review the advances in the use of TIPS in the management of patients with liver cirrhosis and portal vein thrombosis.

Efficacy of endoscopic ultrasound-guided coil placement combined with tissue adhesive injection in treatment of gastric varices with spontaneous shunt / 临床肝胆病杂志

ObjectiveTo investigate the efficacy， safety， and cost-effectiveness of endoscopic ultrasound （EUS）-guided coil placement combined with tissue adhesive injection in the treatment of gastric varices with spontaneous shunt. MethodsA retrospective analysis was performed for the patients with acute gastric variceal bleeding and spontaneous portosystemic shunt who were hospitalized and received balloon-occluded retrograde transvenous obliteration （BRTO） combined with endoscopic tissue adhesive injection or EUS-guided coil placement combined with tissue adhesive injection in Xiangyang Central Hospital from March 2019 to September 2022. The two surgical procedures were compared in terms of efficacy （technical success rate， 5-day rebleeding rate， 1-year rebleeding rate， and time to rebleeding）， safety （the incidence rate of ectopic embolism， the amount of tissue adhesive used， and the amount of lauromacrogol used）， and cost-effectiveness （hospital costs and length of hospital stay）. The t-test was used for comparison of normally distributed continuous data between two groups， and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups. The Kaplan-Meier method was used to estimate the rebleeding. The chi-square test was used for comparison of categorical data between two groups. ResultsA total of 25 patients received successful EUS-guided coil placement and tissue adhesive injection， with a technical success rate of 100%， a median amount of 2.5 mL tissue adhesive used， a median amount of 11.0 mL lauromacrogol used， a mean length of hospital stay of 14.88±3.21 days， a mean hospital cost of 32 660.00±4 602.07 yuan， and a 5-day rebleeding rate of 0%； among these patients， 2 were lost to follow-up， and 23 patients with complete follow-up data had an incidence rate of ectopic embolism of 0% and a median time to rebleeding of 689 days. A total of 14 patients underwent modified BRTO combined with endoscopic tissue adhesive injection， with a technical success rate of 100%； a median amount of 5.0 mL tissue adhesive used during surgery， which was significantly higher than that used in EUS （U=39.000， P<0.001）； a median amount of 10.5 mL lauromacrogol used during surgery； a mean length of hospital stay of 15.38±4.94 days； a mean hospital cost of 57 583.47±18 955.40 yuan， which was significantly higher than that used in EUS （t=-6.310， P<0.001）； a 5-day rebleeding rate of 0%. No patient was lost to follow-up， and all 14 patients had an incidence rate of ectopic embolism of 0% and a median time to rebleeding of 244.50 days， with no significant difference between the two groups （χ2=1.448， P=0.229）. ConclusionEUS-guided coil placement combined with tissue adhesive injection is a relatively safe and effective technique for the treatment of gastric variceal bleeding and has a high technical success rate， a low incidence rate of serious adverse events， and similar efficacy to BRTO， with higher safety and cost-effectiveness.

Research progress in perioperative management of portal vein thrombosis in liver transplantation / 器官移植

Portal vein thrombosis is one of the common complications of liver cirrhosis. The incidence of portal vein thrombosis is increased with the progression of diseases. The incidence and progression of portal vein thrombosis are associated with multiple factors. The indications of anticoagulant therapy remain to be investigated. At present, portal vein thrombosis is no longer considered as a contraindication for liver transplantation. Nevertheless, complicated portal vein thrombosis will increase perioperative risk of liver transplantation. How to restore the blood flow of portal vein system is a challenge for surgical decision-making in clinical practice. Rational preoperative typing, surgical planning and portal vein reconstruction are the keys to ensure favorable long-term prognosis of liver transplant recipients. In this article, epidemiological status, risk factors, typing and identification of portal vein thrombosis, preoperative and intraoperative management of portal vein thrombosis in liver transplantation, and the impact of portal vein thrombosis on the outcomes of liver transplantation were reviewed, aiming to provide reference for perioperative management of portal vein thrombosis throughout liver transplantation.

PERIOPERATIVE CONCERNS OF VENTRICULOATRIAL SHUNT-A RETROSPECTIVE ANALYSIS OF 40 CASES.

Background: Ventriculo -peritoneal [VP] shunt is the most commonly used cerebrospinal ?uid (CSF) diversion procedure for the management of hydrocephalus. However, when the absorption of CSF from the peritoneum is defective, it results in abdominal distension with CSF ascites. In such cases, an alternate diversion procedure - the ventriculo-atrial [VA] shunt – may be performed. However, this procedure is also associated with several perioperative problems like arrhythmias, air embolism and infection. Materials and methods: A retrospective analysis of 40 cases on the perioperative concerns of VA shunt procedures, performed in our institute, was done. Indication of the shunt, preoperative status & work -up, intraoperative adverse events & management and immediate post-operative complications were assessed. Out of the 40 patients, there were 25 male Results: s and 15 females and there were a total of 12 paediatric patients. Blocked shunt, abdominal infection and CSF ascites were common indications for VA shunt. All patients received general endotracheal anaesthesia with preoperative hypovolemia correction. Intraoperative tachycardia and arrhythmia were noted. Various Conclusion : preoperative concerns like distended abdomen and compromised respiration increase risk of VA shunt procedures. A better understanding of the underlying disease pathology and anticipation of related complications along with cautious and meticulous management can help prevent most of the complications of VA shunt procedure and thereby improve outcome

Shunt portosistémico, una causa poco frecuente de hepatitis colestásica en neonatología. A propósito de un caso / Portosystemic shunt, a rare cause of neonatal cholestatic hepatitis. A case report

El shunt portosistémico congénito es una anomalía vascular venosa que comunica circulación portal y sistémica, por la que se deriva el flujo sanguíneo, salteando el paso hepático. Es una entidad poco frecuente, cuya incidencia varía entre 1/30 000 y 1/50 000 recién nacidos. Puede cursar de forma asintomática o presentarse con complicaciones en la edad pediátrica o, menos frecuente, en la edad neonatal. Ante el diagnóstico, se deberá definir la necesidad de intervención quirúrgica o intravascular para el cierre. Esta decisión depende de las características anatómicas de la malformación, de las manifestaciones clínicas y complicaciones presentes. Se presenta el caso de un paciente de un mes de vida derivado a nuestro centro para estudio de hepatitis colestásica neonatal, con diagnóstico de shunt portosistémico extrahepático. Se realizó cierre intravascular de la lesión con mejoría significativa posterior.

Congenital portosystemic shunt is a venous vascular abnormality that connects portal and systemic circulation, resulting in diversion of the blood flow, bypassing the hepatic passage. It is a rare malformation; its incidence varies from 1:30 000 to 1:50 000 newborns. It may be asymptomatic or present with complications in the pediatric age or, less frequently, in the neonatal age. Upon diagnosis, the need for a surgical or an intravascular intervention for closure should be defined. This decision depends on the malformation anatomical characteristics, clinical manifestations, and complications. We present the case of a 1-month-old patient referred to our center for the study of neonatal cholestatic hepatitis, with a diagnosis of extrahepatic portosystemic shunt. Intravascular closure of the defect was performed with significant subsequent improvement.

Transjugular intrahepatic portosystemic shunt combined with collateral vessel embolization in treatment of gastroesophageal variceal bleeding in liver cirrhosis： Research advances and controversies / 临床肝胆病杂志

Transjugular intrahepatic portosystemic shunt （TIPS） has been recommended as a treatment method for cirrhotic portal hypertension in domestic and foreign guidelines， but there is still uncertainty in its therapeutic efficacy. More and more studies have shown that TIPS combined with collateral vessel embolization （TIPS+E） has certain advantages in the treatment of gastroesophageal variceal bleeding in liver cirrhosis. This article reviews the major studies on TIPS+E in China and globally， summarizes related recommendations in guidelines and the current status of clinical application， and proposes the issues that need to be solved， such as indication， hemodynamic criteria， and selection of materials for embolization， and large－sample multicenter randomized controlled trials are needed for further clarification.

Analysis of 5 ischemic stroke patients caused by pulmonary arteriovenous fistula / 中华神经科杂志

Objective:To investigate the correlation between pulmonary arteriovenous fistula (PAVF) and ischemic stroke, and to improve the diagnosis and treatment of embolic strokes of undetermined source.Methods:Five patients with ischemic stroke caused by PAVF admitted to Xiangya Hospital of Central South University from January 2017 to December 2020 were collected. The diagnosis, treatment and prognosis of stroke caused by PAVF were summarized based on literature review.Results:Among the 5 patients, 1 is male and 4 are females, with age of (34.4±9.3) years. Weakness of unilateral limb, slurred speech, vision changes, drooping eyelids, etc., were the first manifestations of stroke. The location of cerebral infarction was indefinite. In this study, 5 patients were all isolated PAVF, including 3 cases of left lower lung, 1 case of left upper lung and 1 case of right lower lung. All 5 patients underwent interventional therapy, were followed-up for 6 months and 12 months after surgery, and none of them had a new stroke attack, and only 1 case had recanalization of PAVF.Conclusions:PAVF is a rare vascular lesion, stroke caused by which is even rarer, with a lack of specificity in clinical manifestations. For young patients with unexplained embolic stroke, if the stroke has a sudden onset, the anterior and posterior circulation can be involved, and multiple vascular distribution regions are often involved, and it is difficult to find a clear emboli basis, with manifestations such as hypoxemia, PAVF should be considered. Percutaneous catheter intervention for PAVF is safe and effective, and is the preferred method for the treatment of PAVF.

Surgical management of Dandy-Walker syndrome in infants and the literature review / 中国综合临床

Dandy-Walker syndrome is one of the posterior fossa malformations, which is easily confused with arachnoid cyst or cerebellar dysplasia in clinical practice, leading to misdiagnosis. Dandy-Walker syndrome is easy to be combined with hydrocephalus, resulting in increased intracranial pressure, increased head circumference, growth retardation, spastic hemiplegia and other manifestations, and can also be accompanied by other nervous system malformations. On February 27, 2021, a child with Dandy-Walker syndrome with growth retardation as the primary manifestation was admitted to Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine. After multiple surgical treatment, the child's hydrocephalus was significantly improved. Through the analysis of the clinical data of the child's operation and the treatment of complications, it is helpful to improve the clinicians' understanding of the surgical treatment of the disease.

Neonatal hydrocephalus: single-center 10-year experiences / 中国新生儿科杂志

Objective:To study the past 10 years' experiences of neonatal hydrocephalus in a single-center.Methods:From January 2010 to December 2019, clinical data of infants with hydrocephalus admitted to Neonatology Department of our hospital were retrospectively analyzed. The infants were assigned into different groups according to gestational age, different etiologies and treatments. Their clinical characteristics and outcomes were compared.Results:A total of 223 infants with hydrocephalus were included. 136 (61.0%) infants were in the preterm group and 87 (39.0%) in the full-term group. The incidence of post-intracranial hemorrhage (ICH) hydrocephalus in preterm infants was significantly higher than full-term infants ( P<0.001). According to the etiologies, 58 infants (26.0%) had congenital hydrocephalus (congenital group), 82 cases (36.8%) developed post-ICH hydrocephalus (ICH group), 48 cases (21.5%) had post-CNS-infection hydrocephalus (infection group) and 35 cases (15.7%) had post-ICH+CNS-infection hydrocephalus (ICH+infection group). The incidences of perinatal asphyxia, neonatal resuscitation and endotracheal intubation within 3 d after birth in the ICH group were significantly higher than the other groups ( P<0.05). Among the four groups, the infection group had the highest incidence of neonatal sepsis, the congenital group had the highest incidence of patent ductus arteriosus and the ICH group had the highest incidence of respiratory diseases (all P<0.05).137 cases (61.4%) received non-surgical therapy, 48 cases (21.5%) had temporary drainage, 37 cases (16.6%) with permanent shunt and 1 case (0.4%) intracranial hematoma removal. The congenital group and ICH group with permanent shunt showed significantly higher rate of improvement than temporary drainage group and non-surgical group ( P<0.001). Conclusions:The main etiologies of neonatal hydrocephalus are ICH and CNS infection. The incidence of post-ICH hydrocephalus in premature infants was quite high. Hydrocephalus of different etiologies have different comorbidities. Maternal and infant care during pregnancy and delivery, prevention of neonatal sepsis and ICH are crucial in the prevention of hydrocephalus. More studies are needed for better treatment.

Predictive value of controlled nutritional status score for overt hepatic encephalopathy after transjugular intrahepatic portosystemic stent-shunt of Budd-Chiari syndrome / 中华消化外科杂志

Objective:To investigate the predictive value of controlled nutritional status (CONUT) score for overt hepatic encephalopathy (OHE) after transjugular intrahepatic portosys-temic stent-shunt (TIPSS) in Budd-Chiari syndrome patients.Method:The retrospective case-control study was conducted. The clinicopathological data of 48 Budd-Chiari syndrome patients who underwent TIPSS in the First Affiliated Hospital of Zhengzhou University from August 2014 to March 2021 were collected. There were 26 males and 22 females, aged (46±13)years. Observation indicators: (1) surgical situations and follow-up; (2) analysis of influencing factors of OHE after TIPSS; (3) predic-tion of OHE after TIPSS. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was performed using the t test. Measurement data with skewed distribution were represented by M( Q1, Q3), and comparison between groups was performed using the Mann-Whitney U test. Count data were expressed as absolute numbers or percentages, and comparison between groups was performed using the chi-square test or Fisher exact probability. Multivariate analysis was performed using the Logistic regression model with forward method. The receiver operating characteristic (ROC) curve was drawn and the area under the curve (AUC) was calculated to evaluate the efficacy. Comparison among AUC was performed using the Delong test. Results:(1) Surgical situations and follow-up. All 48 patients underwent TIPSS successfully, and the operation time of the 48 patients was (131±29)minutes. All patients were implanted with 8 mm covered stent. All 48 patients were followed up for 46(25,71)months, and there were 14 cases with OHE and 34 cases without OHE after TIPSS. Of the 14 cases with OHE, 12 cases were evaluated as West-Haven Ⅱ grade and 2 cases were evaluated as West-Haven Ⅲ grade. (2) Analysis of influencing factors of OHE after TIPSS. Results of multivariate analysis showed that history of hepatic encephalo-pathy and CONUT score were independent factors influencing the incidence of OHE of Budd-Chiari syndrome patients who underwent TIPSS ( odds ratio=8.36, 1.74, 95% confidence interval as 1.02?68.75, 1.12?2.69, P<0.05). (3) Prediction of OHE after TIPSS. Results of ROC curve showed that the AUC of the CONUT score, the Child-Pugh score of liver function and the integrated model of end-stage liver disease (iMELD) score in predicting the incidence of OHE after TIPSS was 0.77(95% confidence interval as 0.64?0.91, P<0.05), 0.71(95% confidence interval as 0.56?0.87, P<0.05) and 0.71(95% confidence interval as 0.53?0.88, P<0.05), respectively, and there was no significant difference between the AUC of the CONUT score and the Child-Pugh score of liver function or the iMELD score ( Z=0.84, 0.59, P>0.05). The optimal cutoff value of CONUT score in predicting the incidence of OHE after TIPSS was 7, with the sensitivity, specificity and Yodon index as 78.6%, 61.8% and 0.40, respectively. Conclusion:The CONUT score can be used to predict the incidence of OHE in Budd-Chiari syndrome patients who underwent TIPSS, and the discrimination of CONUT score is equivalent to the Child-Pugh score of liver function and the iMELD score.

Fístula arteriovenosa post-TIPS, un reto diagnóstico: reporte de caso / Post-TIPS arteriovenous fistula, a diagnostic challenge: case report

La hipertensión portal es una de las principales complicaciones de la cirrosis. El papel de la derivación portosistémica transyugular intrahepática (TIPS, por sus siglas en inglés), ha ganado aceptación como tratamiento efectivo en la hipertensión portal. En los últimos años su técnica se ha ido perfeccionando, disminuyendo la morbimortalidad relacionada con este procedimiento. Describimos un caso de un paciente masculino con cirrosis Child-Pugh 8 y MELD 16, con antecedente de descompensación por sangrado variceal recurrente y trombosis parcial de la vena porta, con un gradiente de presión venosa hepática (GPVH) de 20 mmHg, por lo que es llevado a TIPS como profilaxis secundaria, con un gradiente final post-TIPS de 6 mmHg. Posterior al procedimiento, presentó evolución tórpida con deterioro de las pruebas de bioquímica hepática. Se realizó una angiografía demostrando permeabilidad del TIPS sin progresión de la trombosis portal, y hallazgos anormales inespecíficos de la arteria hepática. Se decidió realizar una arteriografía selectiva, demostrando un pseudoaneurisma de la rama derecha de la arteria hepática y una fístula arteriovenosa de la arteria hepática a las colaterales portales. Se realizó embolización selectiva de la fístula con evolución satisfactoria del paciente.

Portal hypertension is a life-threatening complication of cirrhosis. The role of transyugular intrahepatic portosystemic shunt (TIPS) has gained acceptance as an effective treatment for portal hypertension. In the past few years, its technique has been improved, decreasing the mortality related with the procedure. We describe a case of a male with Child-Pugh 8 and MELD 16 cirrhosis, with previous decompensation of recurrent variceal bleeding and partial thrombosis of the portal vein. TIPS was performed due to a hepatic venous pressure gradient (HVPG) of 20 mmHg. The final measure showed HVPG of 6 mmHg. After the procedure, he presented a torpid evolution with deterioration of liver function tests. An angiography was performed demonstrating patency of the TIPS without progression of portal thrombosis and nonspecific abnormal findings of the hepatic artery. Selective arteriography was performed and revealed a pseudoaneurysm of the right branch of the hepatic artery and an arteriovenous fistula (AVF) from the hepatic artery to portal collaterals. Embolization was performed to treat the fistula with satisfactory evolution of the patient.

Alternativas de manejo intervencionista en el síndrome de Budd-Chiari. Serie de casos y revisión de la literatura / Interventional management alternatives in Budd-Chiari syndrome. Series of cases and review of the literature

La obstrucción en el tracto de salida del flujo venoso hepático, también conocida como síndrome de Budd-Chiari, es una condición infrecuente que causa congestión hepática, hipertensión portal, ne-crosis de los hepatocitos y, eventualmente, falla hepática aguda o crónica. Actualmente, el manejo de esta condición representa un reto para el médico, quien debe estar preparado para determinar la mejor alternativa entre las diferentes opciones terapéuticas disponibles. Este artículo pretende ilus-trar las alternativas del manejo intervencionista de esta enfermedad, a través de una serie de casos de pacientes tratados en el servicio de Radiología Intervencionista de un hospital de referencia de la ciudad de Medellín, entre 2011 y 2017.

Hepatic venous outflow tract obstruction, also known as Budd-Chiari syndrome, is a rare condition that causes hepatic congestion, portal hypertension, hepatocyte necrosis and eventually acute or chronic liver failure. Currently, the management of this condition represents a challenge for the physi-cian, who must be prepared to determine the best alternative among the different therapeutic options available. This article aims to illustrate the alternatives of interventional management of this disease, through a series of cases of patients treated in the Interventional Radiology service of a referral hos-pital in the city of Medellin, between 2011 and 2017.

Value of hepatic venous pressure gradient in preoperative evaluation and prognosis prediction in liver transplant recipients / 器官移植

Hepatic venous pressure gradient (HVPG) is the "gold standard" for the diagnosis of portal hypertension, which could be applied in the evaluation of liver cirrhosis. Combined use of HVPG with model for end-stage liver disease (MELD) scoring system may more accurately match the donors and recipients undergoing liver transplantation for liver cirrhosis, select the appropriate timing of surgery, and provide guidance for bridging treatment for patients on the waiting list for liver transplantation. Besides, HVPG may also predict clinical prognosis of liver transplant recipients, and provide evidence for early detection and intervention of potential complications. Therefore, the value of HVPG in preoperative evaluation and prognosis prediction of liver transplant recipients was reviewed, aiming to provide guidance for clinical diagnosis and treatment of liver transplant recipients before and after surgery.

Pharmaceutical care of patients with antithrombotic therapy after transjugular intrahepatic portal shunt / 中国临床药理学与治疗学

AIM: To explore the role of clinical pharmacist in the treatment of patients with transjugular intrahepatic portosystemic shunt. METHODS: Clinical pharmacist participated in the treatment of a patient with repeated oral bleeding after transjugular intrahepatic portal shunt followed treatment with multiple antithrombotic drugs, which assisted the physician to diagnose and adjust the antithrombotic treatment plan as well as provided the patient with whole-process pharmaceutical care and online management. RESULTS: Based on the inquiry about the patient's past and current medical history and medication consumption, the pharmacist considered that there was weak correlation between oral hemorrhage and antithrombotic drugs and advised for dentist inspection. Thereafter, the patient was diagnosed with chronic gingivitis. The dosage of warfarin was adjusted, and the pharmacists managed it online after discharge to achieve stable INR of the patient. In the later online follow-up, an abnormal increase of INR was encountered, By asking about the history of medication, it was considered that the increase in INR was related to taking amoxicillin capsules. Therefore, the pharmacist suggested to stop amoxicillin capsule and to gradually adjust the dose of warfarin to the original level to improve the treatment. CONCLUSION: The involvement of clinical pharmacists in clinical treatment facilitates comprehensive pharmaceutical care of patients, which plays a positive role in the efficacy and safety of medication therapy.

Association between spontaneous portosystemic shunt and hepatorenal syndrome in liver cirrhosis / 临床肝胆病杂志

ObjectiveTo investigate the association between spontaneous portosystemic shunt （SPSS） and hepatorenal syndrome （HRS） in patients with liver cirrhosis. MethodsA retrospective analysis was performed for 93 patients with SPSS from Dezhou Hospital， Qilu Hospital of Shandong University， from January 2015 to January 2022， and the patients were followed up for 12 months with the onset of HRS as the observation endpoint. According to the presence or absence of HRS， the 93 patients with SPSS were divided into HRS group with 38 patients （40.86%） and non-HRS group with 55 patients （59.14%）， and the two groups were compared in terms of clinical data， laboratory data， complication， and shunt diameter. Based on the maximum shunt vein diameter of 1.5 cm， the 93 patients with SPSS were divided into high shunt group with 52 patients （55.91%） and low shunt group with 41 patients （44.09%）， and with the onset of HRS as the observation endpoint， the two groups were compared in terms of the incidence rate of HRS and survival time curve. The independent-samples t test was used for comparison of normally distributed continuous data with homogeneity of variance between two groups， and the chi-square test was used for comparison of categorical data between two groups. The receiver operating characteristic （ROC） curve was used to predict cut-off values， the Kaplan-Meier curve was used for comparison of survival time， and the Log-rank test was used to compare the differences in survival curves. The multivariate Cox regression analysis was used to investigate risk factors. ResultsCompared with the non-HRS group， the HRS group had significant increases in Child-Pugh score， Child-Pugh class， MELD score， serum creatinine， blood urea nitrogen， alanine aminotransferase， aspartate aminotransferase， maximum shunt vein diameter， the incidence rates of hepatic encephalopathy and spontaneous bacterial peritonitis， and the degree of ascites， as well as significant reductions in main portal vein diameter， serum sodium and albumin （all P<0.05）. Compared with the low shunt group， the high shunt group had a significant increase in the incidence rate of HRS （51.92% vs 26.83%， χ²=5.974， P=0.015） and a significant reduction in the time to the onset of HRS （Log-rank P=0.033）. A maximum shunt vein diameter of >1.5 cm （hazard ratio ［HR］=1.123， 95% confidence interval ［CI］： 1.041‍ ‍—‍ ‍1.211， P=0.003）， an increase in MELD score （HR=1.205， 95%CI： 1.076‍ ‍—‍ ‍1.437， P=0.039）， a reduction in serum albumin （HR=0.890， 95%CI： 0.814‍ ‍—‍ ‍0.974， P=0.011）， an increase in the degree of ascites （HR=2.099， 95%CI： 1.066‍ ‍—‍ ‍4.130， P=0.032）， and spontaneous bacterial peritonitis （HR=2.259， 95%CI： 1.020‍ ‍—‍ ‍5.003， P=0.045） were independent risk factors for the onset of HRS in SPSS patients. ConclusionThere is an association between SPSS and HRS， and shunt diameter >1.5 cm was an independent risk factor for HRS in SPSS patients， which should be taken seriously and require early intervention in clinical practice.

Research advances in congenital extrahepatic portosystemic shunt / 临床肝胆病杂志

Congenital extrahepatic portosystemic shunt (CEPS) is also called Abernethy malformation, with the manifestation of congenital abnormal anastomosis between the portal vein and the inferior vena cava. CEPS is extremely rare in clinical practice and has diverse clinical symptoms, which often leads to missed diagnosis and misdiagnosis. This article reviews the pathogenesis, classification, clinical manifestation, diagnosis, and treatment of CEPS, so as to improve the awareness of this disease and provide a reference for further standardization of its diagnosis and treatment process in the future.

Efficacy of transjugular intrahepatic portosystemic shunt in treatment of primary biliary cholangitis with portal hypertension / 临床肝胆病杂志

Objective To investigate the long-term efficacy of transjugular intrahepatic portosystemic shunt (TIPS) in the treatment of primary biliary cholangitis (PBC) with portal hypertension. Methods A retrospective analysis was performed for 102 patients who received TIPS in Affiliated Drum Tower Hospital of Nanjing University Medical School from January 2015 to August 2021, and these patients were divided into PBC group with 41 patients and viral hepatitis cirrhosis group with 81 patients. Related indicators were collected, including routine blood test results, liver and renal function, coagulation function, portal vein thrombosis, hepatic encephalopathy, and etiology of TIPS treatment shortly after admission, preoperative portal venous pressure, and stents used in surgery, and Child-Pugh score was calculated. Follow-up data were collected and analyzed, including postoperative upper gastrointestinal rebleeding, stent dysfunction, hepatic encephalopathy, and the data on survival and prognosis. The independent samples t -test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of continuous data with skewed distribution between two groups; the chi-square test was used for comparison of categorical data between two groups. The Kaplan-Meier method was used for survival analysis, and the log-rank test was used for survival difference analysis. Results In the PBC group and the viral hepatitis cirrhosis group, the median percentage of reduction in portal venous pressure after surgery was 33.00% and 35.00%, respectively, and there was no significant difference between the two groups ( P > 0.05). At the end of follow-up, there were no significant differences between the PBC group and the viral hepatitis cirrhosis group in stent dysfunction rate (14.63% vs 24.69%, χ 2 =1.642, P > 0.05), upper gastrointestinal rebleeding rate (17.07% vs 24.69%, χ 2 =0.917, P > 0.05), the incidence rate of overt hepatic encephalopathy (12.20% vs 7.41%, χ 2 =0.289, P > 0.05), and disease-specific death rate (14.63% vs 9.88%, χ 2 =0.229, P > 0.05). Conclusion For PBC patients with portal hypertension, TIPS can achieve the same efficacy as the treatment of portal hypertension caused by viral hepatitis cirrhosis and can also effectively reduce portal hypertension without increasing the incidence rate of complications and disease-specific death rate. Therefore, it is a safe and effective treatment method.

Association between transjugular intrahepatic portosystemic shunt and sarcopenia in patients with liver cirrhosis / 临床肝胆病杂志

Sarcopenia is a common complication of liver cirrhosis and is significantly associated with poor prognosis. Transjugular intrahepatic portosystemic shunt (TIPS) is an important method for the treatment of portal hypertension and its complications. Based on current studies, this article analyzes the association between sarcopenia and the outcomes (hepatic encephalopathy and mortality) of patients with liver cirrhosis after TIPS and the value of improving the predictive ability of existing prognostic models for sarcopenia, as well as the improvement in sarcopenia after TIPS and its significance in the clinical management of patients with liver cirrhosis. A comprehensive analysis of existing reports show that baseline sarcopenia is associated with poor prognosis after TIPS, and it is thus recommended to evaluate nutritional status before TIPS based on radiological examination; TIPS can improve nutritional status and help to achieve reversal or improvement of sarcopenia to a certain extent, and it can also be translated into survival benefit. Therefore, for patients with sarcopenia and a relatively stable disease, TIPS can be performed as soon as possible after comprehensive evaluation.
