外文摘要：Budd-Chiari syndrome(BCS)is a rare condition characterized by hepatic venous outflow obstruction.Balloon angioplasty,with or without stenting,is the recommended first-line treatment modality in Asian countries.As a supplement to balloon angioplasty,expandable metallic Z-stent deployment can effectively improve long-term inferior vena cava(IVC)patency.Although stent placement is a standard and frequently performed treatment,very few IVC stent-related complications,such as stent fractures,have been reported.Here we present a case series and a comprehensive review of IVC stent fractures in patients with BCS.The most common characteristic of IVC stent fractures is a protrusion of the proximal segment of the IVC stent into the right atrium and its systolic and diastolic movements along with heart rhythms.Accurate stent deployment,large-diameter balloon dilation,patient breath-holding training,preferential selection of a triple stent,and the use of an internal jugular vein approach to stent deployment may ensure precise stent localization and avoid postoperative complications.
