DSA步进技术诊断下肢动脉疾病中的临床价值探讨

Study on the Clinical Value of DSA Step Technique in the Diagnosis of Arterial Diseases in Lower Limbs

目的：探讨DSA步进技术对下肢动脉疾病的临床诊断价值。方法：选取于本院诊治的45例进行下肢动脉DSA造影检查的患者作为研究对象，收集患者临床资料，并对其做回顾性分析，将其按照检查方式的不同随机分成2组，采用DSA步进技术造影检查的24例患者为观察组，采用传统分段DSA造影检查的21例患者为对比组，对2组患者临床诊断及检查情况进行观察和比较。结果：观察组图像达优率为93．1％，对比组为92．3％，2组患者图像显示情况相比无明显差异（P〉0．05），但观察组检查每侧下肢的对比剂使用剂量、曝光时间与检查耗时均明显少于对比组（P〈0．05）。结论：下肢动脉疾病应用DSA步进技术可充分满足临床诊断需求，其检查耗时短且安全性较高，具有重要临床价值。

Objective： To explore the clinical diagnosis value of DSA stepping technique in lower extremity arterial disease. Methods ： 45 cases of lower extremity artery DSA angiography of patients were selected as the research object. Clinical data were collected, and the retrospective analysis. In accordance with the examination of the different ways were randomly divided into 2 groups. 24 cases were treated with DSA stepper technology angiography of patients as the observation group. 21 cases were treated with traditional piecewise DSA angiog- raphy in patients as contrast group. The two groups of patients with clinical diagnosis and examination were observed and compared. Re- suits： The success rate of 93.1% as observed group, contrast group 92.3%. The patients in the two groups of images compared with no significant difference （ P 〉 0.05）. The observation group examined and compared each lower extremity agent dose, exposure time and the examination time was significantly less than that of contrast group （P 〈 0.05）. Conclusion： Lower extremity arterial disease using DSA stepper technology can fully meet the demand of the clinical diagnosis, examination time is short and high security, and has important clin- ical value.
