Aegisy可回收滤器在下肢深静脉血栓形成治疗中的应用

Aegisy recyclable filter formed in the treatment of deep venous thrombosis of lower extremity

目的：探讨在下肢深静脉血栓治疗中应用Aegisy式可回收滤器的临床效果。方法选取我院创伤骨科收治的急性或亚急性单侧下肢深静脉血栓形成（ DVT）患者92例,Aegisy滤器经股静脉植入下腔静脉,第2天开始进行溶栓治疗,治疗后10～15 d观察患者患肢愈合情况,采用超声以及血管造影证实下肢静脉内无新鲜或游离血栓,采用抓捕器将Aegisy可回收滤器取出,下肢静脉造影术复查,并同时抗凝治疗。结果全部患者置入成功,Aegisy滤器释放均无明显前跳和回缩现象,介入治疗及造影复查过程中,滤器无移位。置入滤器时间平均（16.8±1.3） d,89例患者回收滤器成功。下肢深静脉血栓患者经治疗效果明显,疼痛减轻,无肺动脉栓塞症状。结论 Aegisy可回收滤器能够明显改善下肢深静脉血栓临床症状,具有置入定位准确、捕获血栓能力高、回收成功率高等优点,对临床具有指导意义。

Objective To investigate the therapeutic efficacy of Aegisy retrievable filter in inferior vena cava interventional treatment for acute deep venous thrombosis of lower extremity. Methods Acute or sub acute unilateral lower extremity deep vein thrombosis （ deep vein thrombosis, DVT） patients in our hospital were selected, and Aegisy filter was put into the inferior vena cava through the femoral, and thrombolytic therapy was carried out in the next day. Limb conditions was observation after 10 to 15 days, confirmed by vascular ultrasound and angiography of lower limb vein after no fresh or free thrombus. The filter was removed with protector, anticoagulant therapy after review the venography of lower limb postoperative. Results All Aegisy filter were put into patients, and there were no obvious forward jumping and drawing back occurred during the release of the filters, and all Aegisy filter had a better position. Placement of a filter everage time was （16. 8 ± 1. 3） days, 89 cases were successfully recovery filter. The effct of Aegisy filter on the patients with lower extremity deep venous thrombosis after treatment is obvious effect, no pain, and no symptom of pulmonary embolism. Conclusion Aegisy retrievable inferior vena cava filter has many advantages in clinical use. The filter can be placed to the scheduled position accurately,and it is very powerful in captu-ring the thrombus,it can be hold in the inferior vona cava for long time before it is planed to be retrieved,and its retrieval success is very high. Moreover,with high technieal successful rate the implantation of Aegisy retrievable inferior vena cava filter is very safe and effective for the interventional treatment of acute deep venous thrombosis of lower extremity.
