Objective To explore the feasibility of the Budd-Chiari syndrome model establishment in rat by using the inferior vena cava coarctation. Methods Fifty SD rats were randomly divided into experimental group and sham operation group， the laparotomy was performed after general anesthesia by intraperitoneal injection， and dissociated the inferior vena cava. In the experimental group， the vena cava was tightly ligated with silk thread according to partial portal vein coarctation， enclosing 23 G L-style blunt needle in the ligature to prevent complete obliteration. The diameter of the vena cava was set to about 80% of its normal size after removing the 23 G L-style blunt needle. The abdominal Doppler， liver function， blood routine examination， and liver biopsy were tested at different time （on week 1， 4， 8， and 12） after operation. Results The signs of inferior vena cava and primary hepatic venous obstruction， liver congestion and cirrhosis， ascites， hepatosplenomegaly， portal vein extension， and collateral patency occurred on week 4 in the experimental group. The levels of AST， ALT， AKP， TBIL， DBIL， and TBA in the experimental group were significantly higher than those in the sham operation group （P＜0.05）， and the WBC， PLT， RBC， HGB， and ALB in the experimental group was significantly lower than those in the sham operation group （P＜0.05）. Conclusion The inferior vena cava coarctation can be successfully used to establish a rat model of Budd-Chiari syndrome.
ObjectiveTo evaluate the applicability and the long-term outcomes of percutaneous transluminal balloon angioplasty (PTBA) in the management of Budd-Chiari syndrome (BCS) secondary to hepatic venous obstruction. MethodsClinical data of 94 patients with BCS secondary to hepatic venous obstruction who underwent PTBA of the hepatic vein from Jan. 2005 to Dec. 2013 in The First Affiliated Hospital of Zhengzhou University were analyzed retrospectively. ResultsPTBA were technically successful in 93 of the 94 patients (98.94%). Ninety-one of the 93 patients (97.85%) were treated with PTBA alone and 2 patients (2.15%) were treated with PTBA and stent. One patient with primary hepatocellular carcinoma (HCC) underwent resection of liver cancer after interventional therapy. Hepatic venous pressure value of 93 patients was significantly decreased after balloon interventional procedures. Symptoms were significantly improved in the 93 patients who had successful PTBA. Procedure-related complications occurred in 6 of the 93 patients (6.38%), and 1 patient (1.06%) died in 2 months after operation because of intra-abdominal bleeding. Two patients lost during follow-up with a follow-up loss rate of 2.15% (2/93), and the 91 patients were followed-up for 1-96 months [(49.72±28.60) months]. HCC occurred in 3 patients during follow-up period. Restenosis of targeted hepatic vein developed in 8 patients (11 times), and the overall recurrence rate was 11.83% (11/93). One patient of them underwent surgical operation, the remaining 7 patients underwent PTBA successfully. The 1-, 2-, 3-, and 5-year primary patency rates were 97.47% (77/79), 94.20% (65/69), 91.67% (55/60), and 91.67% (33/36), respectively. The 1-, 2-, 3-, and 5-year secondary patency rates were 98.73% (78/79), 98.55% (68/69), 98.33% (59/60), and 97.22% (35/36), respectively. ConclusionsPTBA is a safe and effective treatment for BCS with the hepatic vein obstruction and had good mild-term outcomes. The liver function of the patients improved after treatment, with few patients died from HCC caused by hepatic cirrhosis, so we must pay attention on it, as well as the targeted hepatic vein.
Objective To summarize the technique and indication of total corrective operation of Budd-Chiari syndrome by open angioplasty. Methods Twelve patients of Budd-Chiari syndrome from November 1997 to September 1999 treated by total open angioplasty were studied. Results About 1 500-2 580ml self-blood was recycled and transfused during the operation. Bank-blood was not required to patients, except one who experienced second thoracectomy for hemostasis after the operation. The pressure of inferior vena cava declined obviously and no complication occurred after operation. All patients were cured. Ultrasonic examination was performed six months after operation and no reocclusion of inferior vena cava was found in these patients.Conclusion Total corrective operation by open angioplasty is efficacy to treat Budd-Chiari syndrome. Controlling hemorrhage of inferior vena cava to maintain a clear operation field is the key to success of operation.
Objective To investigate the imaging features of Budd-Chiari syndrome (BCS) on 64 slice spiral computed tomography (64SCT) and the diagnostic value of 64SCT for BCS. Methods Twenty-nine patients diagnosed as BCS by 64SCT were retrospectively included into this study and all the patients were researched by digital substraction angiography (DSA). Two abdominal radiologists analyzed the CT imaging features of BCS, paying attention to the vascular lesion, the morphology abnormality of the liver and the degree of portal hypertension, with review of DSA findings. Results ①The accuracy of 64SCT for BCS was 93.1% (27/29), and there were 2 false positive cases and no false negative case. The accuracy of 64SCT for those patients with thrombosis of inferior vena cava (IVC) and (or) hepatic vein (HV) was high as compared to those with stenosis of IVC and (or) HV. ②The morphology abnormality of the liver included hepatomegaly (24 cases), low attenuation (27 cases) and inhomogeneous pattern of parenchymal contrast enhancement (5 patients in arterial phase and 19 patients in portal vein phase). ③The images of all the patients showed the features of portal hypertension. Conclusion The accuracy of 64SCT for BCS is satisfactory and the false negative is seldom. The 64SCT could accurately display the morphology abnormality of the liver and the compensatory circulation in BCS patients. For those patients with stenosis of IVC and (or) HV, however, the diagnostic power of 64SCT is limited.
Hepatic sinusoidal obstruction syndrome (HSOS) can be easily missed or misdiagnosed as Budd-Chiari syndrome in clinical practice. The authors displayed the imaging pictures of one patient with HSOS and made a brief description of typical imaging features, underlying pathophysiological mechanisms, and differential diagnosis of HSOS, with the hope of improving the understanding of HSOS and reducing the rates of leak diagnosis or misdiagnosis.
Objective To explore the methods and effect of venous retransfusion of ascites on the treatment of the complicated patients with Budd-Chiari syndrome.Methods Eighteen complicated and (or) recrudescent patients with Budd-Chiari syndrome were treated by venous retransfusion of ascites between March 2006 and July 2009. The changes in abdominal girth, body weight, the urine volume of 24 h, liver function, renal function, and serum electrolyte measurements before and after treatment were compared. Results After retransfusion of 5 000 ml to 7 800 ml (mean 6 940 ml) ascites, the abdominal girth of patients decreased (Plt;0.05), the urine volume of 24 h tended to normal and during which no serious side-effect happened. The levels of serum BUN, CREA, prothrombin time (PT), and activated partial thromboplastin time (APTT) decreased significantly (Plt;0.05), furthermore the levels of total albumen and albumin increased significantly (Plt;0.05). The changes of serum electrolyte measurements were not significant (Pgt;0.05). The follow-up period for all the patients was in the range of 4 to 37 months (mean 19 months). Then 12 patients were treated by the second operation at 3-6 months after discharge. Conclusions The ascites retransfusion provides a safe and effective treatment option for patients with refractory ascites, and yields a higher likelihood of discharge compared with conventional paracentesis. It is useful in improving quality of life and winning the operational chance for such as patients with complicated Budd-Chiari syndrome.
Objective To analyze the prognosis and indications of transjugular intrahepatic portosystemic shunt (TIPS) in patients with Budd-Chiari syndrome (BCS). MethodsPatients with primary BCS who received TIPS in the Department of Gastroenterology, West China Hospital of Sichuan University between February 2009 and February 2020 were retrospectively reviewed. The medical history, preoperative imaging, surgical records, and postoperative outpatient follow-up medical records were recorded. The laboratory indexes before and after operation were compared, and the cumulative free from hepatic encephalopathy rate, stent patency rate, and cumulative survive rate were calculated. Cox proportional hazards model was used to analyze the independent risk factors of hepatic encephalopathy, shunt dysfunction and death. Results A total of 48 patients were included. The main indications for TIPS included variceal bleeding (16 cases), refractory ascites (24 cases), and diffuse obstruction of hepatic vein with acute liver function impairment (8 cases). The cumulative 1 year, 2 years and 3 years of free from hepatic encephalopathy rates were 92.3%, 89.2% and 85.3%, respectively. The stent patency rates were 89.7%, 72.2% and 54.8% at postoperative 1 year, 3 years and 5 years, respectively. The cumulative survival rates were 86.0%, 79.5% and 71.4% at postoperative 1 year, 3 years and 5 years, respectively. Conclusion TIPS can achieve good efficacy in patients with BCS, and most patients receive TIPS for portal hypertension complications rather than acute liver function impairment.
Computational fluid dynamics was used to investigate the effect of the pathogenesis of membranous obstruction of inferior vena cava of Budd-Chiari syndrome with various angles between right hepatic vein and inferior vena cava. Mimics software was used to reconstruct the models from magnetic resonance imaging (MRI) angiograms of inferior vena cava, right hepatic vein, middle hepatic vein and left hepatic vein, and 3DMAX was used to construct the models of 30°, 60°, 90° and 120° angles between right hepatic vein and inferior vena cava, which was based on the reconstructed models.The model was conducted with clinical parameters in terms of wall shear stress distribution, static pressure distribution and blood velocity. The results demonstrated that the differences between wall shear stress and static pressure had statistical significance with various angles between right hepatic vein and inferior vena cava by SPSS. The pathogenesis of membranous obstruction of inferior vena cava had a correlation with the angles between right hepatic vein and inferior vena cava.
ObjectiveTo summarize the differences between Budd-Chiari syndrome (BCS) and hepatic veno-occlusive disease (HVOD). MethodsBased on the current reports about BCS and HVOD, combined with the authors' clinical experience, a review was performed for the 2 kinds of diseases. ResultsBCS and HVOD were both post-hepatic portal hypertension symptoms, and both would result in liver cirrhosis in the late phase. According to the different causes of 2 kinds of diseases clinically, and the corresponding clinical characteristics, most cases can be confirmed by the preliminary judgment. As for the cases without clear diagnosis, corresponding imaging examinations may be helpful, but the final diagnosis depended on the pathologic examination after liver biopsy. ConclusionThere are some differences on the cause, clinical characteristic, and characteristic of images between the BCS and HVOD, that all of them contribute to differential diagnosis.
ObjectiveThe purpose of this study is to apply the method of CO-word analysis to the evidence-based study of the diagnosis and treatment of Budd-Chiari syndrome (BCS), to understand the trend of BCS research in China and to explore the hot spots of BCS in recent years, and to provide new evidence-based data for the clinical practice and experimental research of BCS in China.MethodsIn the Wanfang database, CNKI, and VIP retrieval platform, " Budd-Chiari syndrome” was used as the key word or title. According to the publication time, it was divided into before 1998 (study group 1), 1999–2008 (study group 2), and 2009–2018 years (study group 3). The relationship matrix was established by using the Netdraw tool in Ucinet6.0, and the common words were plotted with the Netdraw tool. The word relation network was used to get the analysis chart of the relation of the word.ResultsThis study found that, Budd-Chiari syndrome, inferior vena cava, hepatic vein, inferior vena cava obstruction, and syndrome were the most frequently used keywords in the study group 1. Budd-Chiari syndrome, inferior vena cava, hepatic venous, interventional therapy, and patients were the most frequent keywords in the study group 2. In the study group 3, Budd-Chiari syndrome, interventional therapy, inferior vena cava, hepatic vein, and patient were the most frequent keywords.ConclusionsHepatic vein type and inferior vena cava type have became a research hotspot in recent years, and the thrombosis mechanism is one of the directions for domestic scholars to study the etiology of BCS. The diagnosis and classification of BCS depend on color doppler ultrasound technology. Many studies focus on the differential diagnosis of BCS and cirrhosis.
