ObjectiveTo summarize clinical applications of inferior right hepatic vein (IRHV) in liver surgery and to provide a basis for clinical applications of IRHV.MethodThe relevant literatures about clinical applications of IRHV in liver surgery in recent years were reviewed.ResultsAs a kind of short hepatic veins, the IRHV directly flowed into the inferior vena cava, often accompanied by the portal vein of the segment Ⅵ. The occurrence rate of IRHV was 80%–90% by the autopsy examination, while which was 10%–30% by the imaging examination. The caliber of IRHV was 0.22–0.95 cm, and its caliber was negatively correlated with the caliber of right hepatic vein. The IRHV played a great role in the classification and treatment of the Budd-Chiari syndrome. According to the Couinaud liver classification method, the IRHV mainly drained the blood of segment Ⅵ. The existence of IRHV expanded the indications of hepatectomy. The reconstruction of IRHV in the liver transplantation could not only reserve the function of donor liver, but could compensatively drain the corresponding liver areas if the acute occlusion of other major hepatic veins happened.ConclusionsIRHV has some important clinical significances in liver surgery. Fully studying course characters and adjacent relationship of IRHV can not only avoid injury during surgery, but also provide a new treatment idea for related liver diseases.
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 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.

ResultsThere were 1 024 cases in our study, 116 cases of them underwent surgery, 908 cases of them underwent interventional surgery; 265 cases underwent inferior vena cava (IVC) balloon dilatation, 464 cases underwent IVC balloon dilatation and stenting, 97 cases underwent open surgery of hepatic vein (HV), 52 cases underwent right atrium femoral vein combined membrane rupture balloon dilation stent, 7 cases underwent caval shunt, 20 cases underwent radical surgery, 45 cases underwent IVC-right atrium bypass, 6 cases underwent intestinal cavity-real shunt, 9 cases underwent intestinal cavity-neck combined shunt, 30 cases underwent transjugular intrahepatic portosystemic shunt, 29 cases underwent intestinal-line real shunt. There were 902 cases were followed-up for 1 day-19 years (13 years on average), and the application of many kinds of operation strictly and flexibly brought satisfactory results for cases of BCS. ConclusionsThe diagnosis and classification of BCS will help us to make safe, effective, and appropriate treatment plan. In addition, we must use color Doppler ultrasound to observe the pathological changes of the situation, in this way we can have a clear goal in the treatment process.
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.
Objective To explore the effect of endovascular treatment guided by ultrasonography combined with portosystemic shunts on the patients with Budd-Chiari Syndrome （BCS）.Methods The clinical data of 136 patients with BCS treated by balloon angioplasty and stent implantation guided by Doppler ultrasonography in our hospital from January 1995 to January 2011 were retrospectively analyzed.After balloon angioplasty,53 patients were treated by inferior vena cava （IVC） stent implantation and 31 patients with hepatic venous occlusion underwent portosystemic shunts （PSSs） at one week after endovascular treatment.The long-and short-term effects after treatment were studied.Results After endovascular procedures,the IVC pressure of patients significantly decreased （P＜0.01）,while IVC diameter, flow velocity in the lesion,and right atrial pressure of patients showed significant increase（P＜0.01）.Slight heart dysfunction appeared in 13 cases of patients.After shunting,acute pancreatitis occurred in 3 cases, and 1 patient died of upper gastrointestinal hemorrhage on the 10 d after PSSs.Doppler ultrasonography for IVC and shunt vessels showed：the swollen liver and spleen lessened on 3d after endovascular procedures.The swollen liver lessened 2-7cm （mean 5.5cm）,swollen spleen lessened 3-8cm （mean 5.8cm）, and the time of ascites disappearance was 3-60d （mean 14d）.All the patients were followed up for 1 month to 15 years with an average of 3 years.Restenosis of the distal part of stent was found in 1 patient in 2 years after operation, hepatic vein occlusion occurred in 1 case in 1 year after treatment,hepatocellular carcinoma occurred in 1 patient in 3 years after stent implantation,and 1 patient died of C type hepatitis after 1 year,and 5 out of 6 cases of patients with infertility had babies after 1 year.All patients had no stent migration or occlusion of shunts and the symptoms of portal hypertension were obviously relieved.Conclusions Endovascular treatment guided by Doppler ultrasonography is a convenient,safe,and effective method for BCS.Portosystemic shunts are commended to patients with hepatic venous occlusions.The above mentioned methods provide a feasible and effective means for IVC stenosis and short segment occlusion with hepatic vein occlusion of BCS.
Cava-atrial shunt was performed in the Treatment of Budd-Chiari syndrome in two cases, in which one belonged to type Ⅲ， and the oother type Ⅱ,the recent results were satidgactory. A rare cause of Budd-Chiari syndrome in one case is that some drugs for occluding the spermiduct was inadveretntly injected into the spermatic vein and inferior vana 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.
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.
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.
