Evaluate the efficacy of double Gianturco expandable metallic stents for stenosis of the inferior vena cava (IVC) after orthotopic liver transplantation (OLT).
Three patients developed severe Budd-Chiari syndrome secondary to suprahepatic caval stenosis after OLT. Percutaneous angioplasty (PTA) of the stenoses was unsuccessful. Therefore double Gianturco expandable metallic stents, connected in tandem, were deployed at the site of the stenoses.
One double stent was successfully and definitively deployed in patient 1. Partial dislocation of the upper and lower stents comprising the double stent occurred in patient 2. The double stent initially implanted across the stenosis became displaced in patient 3. The Budd-Chiari syndrome resolved in all three patients who remained asymptomatic during follow-up from 3 to 32 months.
Double Gianturco stent deployment is a viable option in patients with anastomotic stenosis of the IVC secondary to OLT when initial treatment with PTA fails. Certain modifications of the stents employed are suggested for the purpose of avoiding technical complications.
评估双枚Gianturco可扩张金属支架治疗原位肝移植（OLT）后下腔静脉（IVC）狭窄的疗效。
3例患者在OLT后因肝上腔静脉狭窄继发严重布加综合征。对狭窄部位进行经皮血管成形术（PTA）未成功。因此，在狭窄部位串联植入了双枚Gianturco可扩张金属支架。
患者1成功且确切地植入了一枚双支架。患者2中构成双支架的上下支架发生部分移位。患者3中最初植入跨越狭窄部位的双支架发生移位。所有3例患者的布加综合征均得到缓解，在3至32个月的随访期间均无症状。
当PTA初始治疗失败时，双枚Gianturco支架植入是OLT继发IVC吻合口狭窄患者的可行选择。为避免技术并发症，建议对所用支架进行某些改进。
