摘要
目的探讨多普勒血流检查中节段性压力比值对评估下肢动脉硬化闭塞症患者远端动脉流出道的应用价值，以对人工血管旁路术适应证的选择提供参考。方法回顾性分析北京安贞医院血管外科1998-2005年收治的166例下肢动脉硬化闭塞症行人工血管旁路术患者的资料，分析流出道节段性压力比值差值等与人工血管通畅率相关的因素，比较人工血管通畅组与阻塞组术前流出道节段性压力比值差值的差异。结果流出道的节段性压力比值差值是影响人工血管术后通畅率危险程度最高的相关因素之一。人工血管通畅组与阻塞组流出道节段性压力比值差值分别为0．12±0．09和0．24±0．14，两组间比较，差异有统计学意义（P=0．001）。人工血管通畅组流出道的节段性压力比值差值的95％可信区间为（0，0．27）。结论多普勒血流检查是一种量化的检查方法，节段性压力比值差值的区间范围可以作为临床上评价流出道及预测手术通畅率的参考。
Objective To explore segmantal blood pressure ratio in Doppler ultrasound in the evaluation of distal outlets in lower extremity atherosclerosis ocllusion patients undergoing blood vessel prosthesis and provide references to surgical indications. Methods A review research was made on 166 lower extremity atherosclerosis ocllusion patients receiving blood vessel prosthesis therapy in Anzhen hospital in 1998-2005. We analyzed related factors including segmantal blood pressure ratio to patency rate, evaluated the difference of segmantal blood pressure ratio between groups in which the blood vessel prosthesis was patent and that it was not. Results The difference of segmantal blood pressure ratio of outlet is one of the highest risk among risk factors. The Mean ± SDs of segmantal blood pressure ratio of outlet in patent and obstructed groups were 0. 12 ± 0. 09 and 0. 24 ±0. 14 respectively. The difference of segmantal blood pressure ratio of outlet has a significant difference between the two groups （ P = 0. 001 ）. The corresponding 95% confidence interval of patent group is （0,0. 27）. Conclusion Doppler ultrasound is a quantitative testing method. The confidence interval of the difference of segmantal blood pressure ratio could be used as the primary reference standard for the assessment of the outlet and to expect the patency rate before the vascular surgical procedures.
