The usefulness of vascular stenting was demonstrated in both arterial and venous applications to restore patency and improve suboptimal results after percutaneous transluminal angioplasty. Dislodgment of venous stents with an embolization into the right cavities or the pulmonary artery, however, is one of the most feared complications of this procedure. Percutaneous removal of these migrated stents is an appealing method of replacing more invasive operative intervention with cardiopulmonary bypass, which may be very hazardous in these often severely ill patients. We describe the cases of two patients with stents that migrated into the right ventricle and the pulmonary artery. In one patient, we were able to successfully remove these stents by using an angioplasty balloon with an operative extraction from the iliac vein, thereby obviating the need for a major operative procedure.
血管支架植入术在动脉和静脉应用中均已证明其有效性，可恢复血管通畅性并改善经皮腔内血管成形术后不理想的结果。然而，静脉支架移位并栓塞至右心腔或肺动脉是该手术最令人担忧的并发症之一。经皮取出这些移位的支架是一种有吸引力的方法，可替代需要体外循环的更具侵入性的手术干预，而体外循环在这些通常病情严重的患者中可能非常危险。我们描述了两例支架移位至右心室和肺动脉的患者病例。在一名患者中，我们通过使用血管成形术球囊并从髂静脉进行手术取出，成功移除了这些支架，从而避免了进行大型手术。
