双导丝球囊扩张联合紫杉醇灌注治疗股动脉支架再狭窄1例

Dual guide wire balloon dilatation together with paclitaxel infusion for the treatment of femoral artery in-stent restenosis

目的应用双导丝球囊扩张联合紫杉醇灌注治疗股动脉支架再狭窄的可行性。方法利用双导丝球囊扩张联合紫杉醇灌注技术治疗1例股腘动脉支架长段闭塞病例。手术顺利,无手术并发症。结果患者术中未出现夹层及血栓,术后下肢缺血症状改善。动脉造影提示原支架闭塞段血流恢复通畅。结论该技术治疗下肢动脉支架再狭窄安全可行,需要更多治疗例数和远期随访结果观察。

Objective To explore the feasibility of using dual guide wire balloon catheter （VASCUTRAK） dilatation together with paclitaxel infusion in treating femoral artery in-stent restenosis. Methods Dilatation angioplasty using dual guide wire balloon catheter combined with infusion of paclitaxel was employed in treating one patient with femopopliteal long-segment in-stent occlusion. The interventional procedure was successfully accomplished, with no occurrence of procedure-related complications. Results During the interventional manipulation, no arterial dissection or thrombosis occurred. After the treatment, the ischemic symptoms of lower extremities were improved. Postoperative angiography showed that the blood flow in previously occluded segment of stent restored unobstructed. Conclusion For the treatment of femoral artery in- stent restenosis, dual guide wire balloon dilatation together with paclitaxel infusion is safe and feasible, however, more clinical practice and long-term follow-up observation are needed before the clinical value of this technique can be clear and definite.
