Long-term effect of stent placement in 115 patients with Budd-Chiari syndrome.
OBJECTIVE
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 and two patients had IVC stent placement, 30 patients had HV stent placement, 17 of them underwent both IVC stent and HV stent. All the procedures were performed with guidance of ultrasound.


RESULTS
The successful rates in placing IVC stent and HV stent were 94% (96/102) and 87% (26/30), respectively. Ninety-seven patients with 112 stents (90 IVC stents, 22 HV stents) were followed up. 96.7% (87/90) IVC stents and 90.9% (20/22) HV stents remained patent during follow up periods (mean 49 months, 45 months, respectively). Five 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.


CONCLUSIONS
Patients with BCS caused by short length obstruction can be treated by IVC stent placement, HV stent placement or both IVC and HV stent placement depending on the sites of obstruction. The long-term effect is satisfactory. Anticoagulants are strongly recommended after the procedure especially for BCS patients caused by segmental occlusion.
