Objective:To explore the risk factors of short-term prognosis of severe Budd-Chiari syndrome (BCS) patients,established and verified the nomogram prediction model for these BCS patients and evaluated its clinical application value.Methods:This study is a retrospective cohort study. The clinical data of 171 patients with severe BCS diagnosed were retrospectively analyzed in the Department of Hepatopancreatobiliary Surgery First Affiliated Hospital of Zhengzhou University from January 2018 to December 2023. There were 105 males and 66 females, aged (52.1±12.8) years (range: 18 to 79 years). The patients were divided into two groups based on whether they died within 28 days: the death group ( n=38) and the survival group ( n=133). The risk factors for short-term death of patients were analyzed,and independent risk factors were screened by univariate and multivariate analysis. Furthermore,these factors were used to establish the nomogram prediction model. The area under the curve(AUC),the Bootstrap Resampling,the Hosmer-Lemeshow test and the Decision Curve Analysis(DCA) were used to verify the model′s differentiation,internal verification,calibration degree and clinical effectiveness,respectively. Results:Univariate and multivariate Logistics regression analysis showed that the history of hepatic encephalopathy,white blood cell,glomerular filtration rate and prothrombin time were independent risk factors ( P<0.05). The above factors were used to successfully establish the prediction model with 0.908 of AUC and 0.895 of the internal verification of AUC,indicating that the predictive model was valuable. The 0.663 P-values in the Hosmer-Lemeshow test indicated the high calibration degree of the model. The clinical effectiveness of the model was proved by the 18% clinical benefit population using the DCA curve with the 17% probability threshold. Conclusions:The independent risk factors are the history of hepatic encephalopathy,white blood cell,glomerular filtration rate and prothrombin time. An adequate basis was acquired by establishing a nomogram prediction model of the short-term prognosis of severe BCS,which was helpful for early clinical screening and identification of high-risk patients with severe BCS who could die in the short term and timely providing timely intervention measures for improving the prognosis.

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.

Objective:To investigate the predictive value of trigeminal nerve vascular compression grading evaluated by preoperative magnetic resonance imaging (MRI) in patients with trigeminal neuralgia (TN) after microvascular decompression (MVD).Methods:Two hundred and seventy patients with TN accepted MVD in our hospital from January 2015 to December 2017 were chosen in our study; their clinical and MRI data were retrospectively analyzed. By referring to Sindou's method and Jannetta standard, these patients were divided into patients with mild vascular compression ( n=71) and patients with severe vascular compression ( n=199) according to preoperative MRI data; these patients were divided into typical TN patients ( n=219) and atypical TN patients ( n=51) according to their symptomatic characteristics; the differences in prognoses after one year of follow-up were compared among patients from different categories. Results:The degree of intraoperative vascular compression was basically consistent with the preoperative imaging evaluation results, and the intraoperative vascular compression in 256 patients was consistent with preoperative imaging evaluation grading, with a coincidence rate of 94.8% (256/270). The difference in prognosis between patients with mild vascular compression and patients with severe vascular compression was statistically significant ( Z=-3.420, P=0.001), and the mean rank indicated that the prognosis of patients with severe vascular compression was better than that of patients with mild vascular compression (142.01 vs. 117.25). The prognosis difference between typical TN patients and atypical TN patients was statistically significant ( Z=-5.810, P=0.000), and the mean rank indicated that the prognosis of typical TN patients was better than that of atypical TN patients (144.45 vs. 97.08). Conclusions:Preoperative MR imaging evaluation is a reliable method to assess the degree of vascular compression. Patients with severe vascular compression and typical TN have high postoperative pain relief rate after MVD.
