Instent restenosis (ISR) following iliofemoral venous stenting is quite common with up to three-quarters of patients developing some degree of ISR. However, only around 16% develop recurrent symptoms impairing their quality-of-life meriting reintervention. The first line of treatment for such ISR involves the use of angioplasty balloons to recreate an adequate flow channel. At times such angioplasty alone is inadequate particularly in the presence of calcified ISR. It is in this setting that the authors decided to explore the utility of a mechanical thrombectomy device to debulk the ISR and thereby help create an adequate flow channel. The successful utilization of such a device in a patient presenting with recurrent, disabling, quality of life impairing symptoms due to ISR represents the focus of this report.
髂股静脉支架置入术后即刻再狭窄（ISR）相当常见，多达四分之三的患者会出现一定程度的 ISR。然而，只有约 16%的患者会出现复发性症状，从而影响其生活质量，需要再次干预。对于此类 ISR 的一线治疗方法涉及使用血管成形术球囊来重新创建一个足够的血流通道。但有时仅进行血管成形术是不够的，特别是在存在钙化 ISR 的情况下。正是在这种情况下，作者决定探索使用机械血栓切除术装置来清除 ISR，从而帮助创建一个足够的血流通道。本报告的重点是介绍一位因 ISR 而出现复发性、致残性、生活质量受损症状的患者，成功使用这种设备的情况。
