Conventional techniques for central venous recanalization are successful in crossing most lesions but still fail in many patients. We used a radiofrequency wire in these failed cases. We report three patients with complicated central venous occlusions in whom conventional catheter and guidewire techniques were not successful and who were successfully treated using the PowerWire Radiofrequency Guidewire (Baylis Medical Company Inc, Montreal, QC, Canada). Occlusions were traversed using the radiofrequency wire, followed by angioplasty and stenting. The average length recanalized was 8.2 ± 3.6 cm. One patient required repeat angioplasty at 4 months. All stents were patent at 12 to 15 months. The radiofrequency wire is valuable in the management of patients with refractory central venous occlusions.
传统的中心静脉再通技术在穿过大多数病变方面是成功的，但仍有许多患者失败。在这些失败的病例中，我们使用了射频丝。我们报告了 3 例复杂的中心静脉阻塞患者，他们使用传统的导管和导丝技术均未成功，而使用 PowerWire 射频导丝（Baylis Medical Company Inc，加拿大魁北克省蒙特利尔）成功治疗。使用射频丝穿过阻塞部位，然后进行血管成形术和支架置入术。再通的平均长度为 8.2 ± 3.6cm。1 例患者在 4 个月时需要重复血管成形术。所有支架在 12 至 15 个月时均保持通畅。射频丝在治疗难治性中心静脉阻塞患者中具有重要价值。
