The Amplatz Thrombectomy Device (ATD) is a percutaneous, rotational thrombectomy catheter, capable of recirculating and homogenizing the thrombus in order to obtain mechanical clot dissolution. The authors present their experience with mechanical thrombectomy with the ATD in eight cases of ilio-caval thrombosis. Under temporary caval filter protection, the ATD was introduced through the right transjugular approach (in one patient this was used in combination with the right femoral approach) and activated for a time ranging from 90 to 180 s. Complete clearing of thrombotic material in the treated venous segments was achieved in six cases (75 %), partial success was obtained in one case (12.5 %) and failure occurred in one patient (12.5 %). One patient developed a recurrence of venous iliac thrombosis 1 week after the procedure and postphlebitic syndrome 6 months after the first episode of deep venous thrombosis, and one patient died from acute myocardial infarction, unrelated to thrombectomy session, after 3 days. A negative clinical and radiological follow-up at 3, 6, 12 and 24 months was obtained in the remaining six patients. If a fresh free-floating ilio-caval clot must be removed immediately, the ATD can be effective under temporary filter protection.
Amplatz血栓切除术装置（ATD）是一种经皮旋转血栓切除术导管，能够使血栓再循环并使其均匀化，以实现机械性血栓溶解。作者介绍了他们使用ATD进行机械性血栓切除术治疗8例髂股静脉血栓形成的经验。在临时下腔静脉滤器保护下，通过右颈静脉途径（1例患者联合右股静脉途径）置入ATD，并启动90至180秒。6例（75%）患者治疗的静脉段血栓物质完全清除，1例（12.5%）部分成功，1例（12.5%）失败。1例患者术后1周出现髂静脉血栓复发，深静脉血栓形成首次发作后6个月出现血栓后综合征，1例患者在术后3天死于急性心肌梗死，与血栓切除术无关。其余6例患者在3、6、12和24个月时临床及影像学随访结果均为阴性。如果必须立即清除新鲜的游离髂股静脉血栓，在临时滤器保护下，ATD可能有效。
