AIM:To report the long-term effect of stent placement in115 patients with Budd-Chiari syndrome (BCS).METHODS:One hundred and fifteen patients with BCS weretreated by percutaneous stent placement.One hundred andtwo patients had IVC stent placement,30 patients had HVstent placement,17 of them underwent both IVC stent andHV stent.All the procedures were performed with guidanceof ultrasound.RESULTS:The successful rates in placing IVC stent andHV stent were 94 % (96/102) and 87 % (26/30),respectively.Ninety-seven patients with 112 stents (90 IVC stents,22HV stents) were followed up.96.7 %(87/90) IVC stents and90.9 %(20/22) HV stents remained patent during follow upperiods (mean 49 months,45 months,respectively).Five of112 stents in the 97 patients developed occlusion.Absenceof anticoagulants after the procedure and types of obstruction(segmental and occlusive) before the procedure were relatedto a higher incidence of stent occlusion.CONCLUSION:Patients with BCS caused by short lengthobstruction can be treated by IVC stent placement,HV stentplacement or both IVC and HV stent placement dependingon the sites of obstruction.The long-term effect is satisfactory.Anticoagulants are strongly recommended after theprocedure especially for BCS patients caused by segmentalocclusion. AIM: To report the long-term effect of stent placement in 115 patients with Budd-Chiari syndrome (BCS). METHODS: One hundred and fifteen patients with BCS were treated by percutaneous stent placement. One hundred andtwo patients had IVC stent placement, 30 patients had HVstent placement, 17 of them underwent both IVC stent andHV stent. All of the procedures were conducted with guidanceof ultrasound.RESULTS: The successful rates in placed IVC stent andHV stent were 94% (96/102) and 87% (26/30), respectively. Ninety-seven patients with 112 stents (90 IVC stents, 22HV stents) were followed up.96.7% (87/90) IVC stents and90.9% (20/22) HV stents remained patent during follow upperiods (mean 49 months , 45 months, respectively). Of of 112 stents in the 97 patients developed occlusion. Absence of anticoagulants after the procedure and types of obstruction (segmental and occlusive) before the procedure were related to a higher incidence of stent occlusion. CONCLUSION: Patients with BCS caused by short lengthobstruc tion can be treated by IVC stent placement, HV stent placement or both IVC and HV stent placement depending on the sites of obstruction. long-term effect is satisfactory. Anticoagulants are strongly recommended after the procedure particularly for BCS patients caused by segmental occlusion.
