Catheter-directed therapies in chronic deep vein thromboses can help improve leg function by mechanically addressing residual obstruction in lower extremity or pelvic veins, although the reported use of stents in leg veins is relatively unusual. The author reports a case of this type with long-term patency and clinical success, culminating in asymptomatic delayed venous migration of a stent to the right atrium after 3 years. Open heart surgery was required to remove the embedded stent fragments. The attributed mechanism was deep tissue massage of the thigh.
慢性深静脉血栓形成的导管定向治疗可通过机械方式解决下肢或盆腔静脉的残余梗阻，从而有助于改善腿部功能，尽管报道中在腿部静脉使用支架的情况相对少见。作者报告了这样一例具有长期通畅性且临床成功的病例，最终在3年后出现支架无症状地延迟迁移至右心房。需要进行心脏直视手术来取出嵌入的支架碎片。推测的机制是大腿深部组织按摩。
