Twenty-eight patients with severe superior and inferior vena cava syndromes were treated with self-expandable Gianturco stents. Nineteen patients responded, seven did not respond, and two were unevaluable. Fourteen of the 19 who responded had complete or near complete resolution of their syndrome, and five had a partial remission. Five of the responders did not derive any benefit from stent placement because of additional problems that led to their death within 3 weeks of the stent placement procedure. The main cause for failure was the relatively weak expansile force of the stent. Complications included stent migrations without untoward effects in one patient, stent misplacement in one patient, fracture of the stent wire in two patients, and hemorrhage that could be attributed to the stent in one patient. This uncontrolled study suggests that caval obstruction syndromes in some patients may be effectively palliated with Gianturco stents.
28例患有严重上、下腔静脉综合征的患者接受了自膨式朱安特科支架治疗。19例患者有反应，7例无反应，2例无法评估。19例有反应的患者中，14例综合征完全或接近完全缓解，5例部分缓解。5例有反应的患者因其他问题在支架置入术后3周内死亡，未从支架置入中获益。失败的主要原因是支架的扩张力相对较弱。并发症包括1例患者支架移位但无不良影响，1例患者支架放置错误，2例患者支架钢丝断裂，1例患者出血可归因于支架。这项非对照研究表明，某些患者的腔静脉阻塞综合征可用朱安特科支架有效缓解。
