摘　　要：目的研究使用双筒压力注射器在下肢深静脉数字减影血管造影(Digital Subtraction Angiography,DSA)中临床应用的可行性和价值。方法59例临床诊断为下肢静脉疾病的患者,随机分成两组,对照组使用单筒高压注射器注射对比剂,实验组使用双筒压力注射器按顺序注射对比剂和生理盐水,行下肢静脉DSA,并比较两组在对比剂排空和影像质量上的差异。结果实验组髂静脉和下腔静脉的显示清晰率高于对照组32.07%和26.96%。实验组胫腓段静脉、股腘段静脉、髂静脉和下腔静脉的排空时间分别比对照组快(28.99±8.21)、(20.80±5.15)、(12.11±2.89)、(5.25±3.04)s,两组比较具有统计学意义(P<0.05)。结论使用双筒压力注射器行下肢深静脉DSA,在对比剂排空和影像质量上优于使用单筒压力注射器,且安全可行。Objective To study the feasibility and value of clinical application of double cylinder pressure injector in digital subtraction angiography(DSA)of deep vein of lower extremity.Methods A total of 59 patients with lower extremity venous disease were selected as the research objects.All patients were randomly divided into two groups,the control group used a single high-pressure syringe to inject contrast medium,while the experimental group used double cylinder pressure syringe to inject contrast medium and normal saline in sequence,and then the two groups underwent DSA of lower extremity vein.The differences of contrast medium emptying and image quality between the two groups were compared.Results The clear rate of iliac vein and inferior vena cava in experimental group was higher than that in control group(32.07%and 26.96%).The emptying time of tibiofibular vein,femoral popliteal vein,iliac vein and inferior vena cava in experimental group was(28.99±8.21),(20.80±5.15),(12.11±2.89)、(5.25±3.04)s,respectively,which were statistically significant(P<0.05).Conclusion DSA of lower extremity deep vein with double cylinder pressure syringe is better than that of single cylinder pressure injector in contrast medium emptying and image quality,and it is safe and feasible.
