血管内支架在髂股静脉血栓形成介入治疗中的应用

The application of endovascular stent for the interventional treatment of iliofemoral deep venous thrombosis

目的 探讨血管内支架在髂股静脉血栓形成介入治疗中的应用价值。方法 2 0 0 1年 1月～ 2 0 0 3年 8月 ,对 38例接受综合性介入治疗的髂股静脉血栓形成的患者施以血管内支架植入术 ,术后口服抗凝治疗。术后 1、3、6、12个月定期临床随访 ,并通过静脉造影或超声检查支架开通情况。结果 38例患者在接受综合性介入治疗的基础上 ,对其残存狭窄 >30 %的病变之髂股静脉成功植入血管内支架。其中 35例患者支架植入后临床症状明显改善 ,术后平均住院日为 7.8d ;另外 3例支架植入后症状改善不明显 ,术后 6个月造影显示支架内闭塞。结论 在髂股静脉血栓形成介入治疗中应用血管内支架可有效地解决髂股静脉节段性狭窄闭塞的基础病变 ,从而提高疗效。

Objective To evaluate the value of the endovascular stent placement for the interventional treatment of iliofemoral deep venous thrombosis. Methods Stent placement was attempted in 38 patients with iliofemoral deep venous thrombosis simultaneously with general combined interventional therapy from January 2001 to August 2003. All patients continued to receive oral anticoagulation therapy and were followed-up by means of clinic visits, and stent patency was assessed by means of venography or Doppler sonography performed at 1,3,6 and 12 months, and then yearly thereafter. Results On the basis of combined interventional therapy, all 38 patients were successfully placed with endovascular stents in iliofemoral veins because of residual narrowing greater than 30% luminal diameter. The notable amelioration of symptoms in 35 patients appeared after stent placement with their average resident date about 7.8 days. The effect was unsatisfied in another 3 patients, resulting with stents occlusion through venography at 6 months after the stent placement. Conclusions The application of endovascular stent for the interventional treatment of iliofemoral deep venous thrombosis can solve the basic lesions of the segmental occlusion or stenosis and thus increase the therapeutic efficacy.
