杂交技术治疗下肢动脉人工血管旁路术后再闭塞的效果

HYBRIDIZATION TECHNIQUE IN THE TREATMENT OF VASCULAR PROSTHESIS BYPASS GRAFT THROMBOSIS IN PATIENTS WITH LOWER EXTREMITY ARTERIAL OCCLUSIVE DISEASE

目的总结杂交技术治疗下肢动脉人工血管旁路术后再闭塞的体会,探索合理的治疗方法。方法2006年12月—2010年7月,我科应用杂交技术治疗下肢动脉人工血管旁路术后再闭塞病人16例,回顾性分析其临床资料,其中行单纯人工血管取栓6例,人工血管取栓+腔内吻合口成形术10例。结果 16例手术均获得成功,手术时间为(40±15)min,出血量均<100mL。术后1年随访时人工血管通畅13例,保肢15例。结论杂交技术治疗下肢动脉人工血管旁路术后再闭塞,对提高人工血管术后通畅率和保肢率有重要作用。

Objective To summarize the experience on using hybridization technique for thrombosis of prosthetic bypass in patients with ischemic disease of lower extremity,and explore a possible therapy of this condition. Methods Clinical data of 16 patients treated in our department for embolism after vascular prosthesis bypass,during the period from December 2006 to July 2010,were analyzed retrospectively.Of whom,six were treated with simple thrombectomy,and 10 underwent thrombectomy plus intracavitary anastomotic plasty. Results All the surgery was successful.Operation time was（40±15） min,with blood loss less then 100 mL.A follow-up one year after surgery showed that the prothesis was unobstructed in 13 patients,the extremity was retained in 15 patients. Conclusion Hybridization tecnique plays an important role in treating re-occlusion of vascular prothesis,in keeping its potency rate and retaining the affected extremity.
