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.
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.
目的 探讨布加综合征肠房转流术后顽固性腹水的治疗。方法 对2008年收治的1例经多次治疗(包括肠房转流术)后均于短期内复发的布加综合征患者进行回顾性分析。结果 临床表现为重度腹水致呼吸困难，CT静脉造影检查示肠房人工血管通畅但血流量低，考虑吻合口狭窄所致。术中探查发现吻合口极度狭窄，用带外支撑环的补片重建吻合口，疗效满意。结论 复杂或经多次手术或介入治疗的布加综合征患者，要遵循个体化治疗原则，强调术前明确诊断及选择正确治疗方案和手术方式。
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.
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.
【Abstract】ObjectiveTo report the author’s experience with the first case of an adult-to-adult living donor liver transplantation (LDLT) for Budd-Chiari syndrome (BCS) using cryopreserved vena cava graft in postheptic vena cava reconstruction. MethodsA 35-year-old male patient with a diagnosis of BCS complicated with inferior vena cava (IVC) obstruction received medical treatment and radiologic intervention for nine months, no relief of the symptoms could be achieved. Finally, the patient underwent LDLT, which required posthepatic vena cava reconstructed using cryopreserved vena cava graft. ResultsThe patient has had an uneventful course since the LDLT. ConclusionWe believe that LDLT combined with posthepatic IVC reconstruction using cryopreserved vena cava graft is considered to be a sound modality for IVC obstructed BCS.
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.
