中文摘要：

目的：探讨超声结合数字减影血管造影（DSA）引导下颈内静脉置管的临床应用价值.方法：选取62例行颈内静脉穿刺中心静脉置管手术患者作为研究对象,随机分为传统盲穿组A组（n=24）和超声＋DSA引导组B组（n=38）.传统盲穿组采用传统体表解剖标志定位穿刺,超声＋DSA引导组经超声引导穿刺后于DSA显影下中心静脉置管.比较两组穿刺置管准确率和首次透析效果.结果：超声结合DSA组穿刺置管准确率达100%,首次透析血流量及效果等指标均高于传统盲穿组,差异具有统计学意义（P〈0.05）.结论：超声引导穿刺后结合DSA下颈内静脉置管的效果明显优于传统体表解剖标志定位下的盲穿置管.

英文摘要：

AIM： To investigate the clinical application value of guidance by ultrasound combined with digital subtraction angiograplay for internal jugular vein cannulation. METHODS： A total of 62 patients with internal jugular vein cannulation surgery were randomly divided into traditional blin of procedure group, Group A （n=24） and uhrasound＋DSA guidance group, Group B （n= 38 ）. In the traditional blin of procedure group, the patients＇ internal jugular veins were cannulated using the traditional method of anatomic landmarks. In the ultrasound ＋ DSA group, cannulation was guided using an ultrasound combined with DSA imaging. The success rate and the dialysis effects of the first time were recorded in the 2 groups. RESULTS ： The success rate of the internal jugular vein cannulation with ultrasound combined with DSA was 100%. The dialysis effect of the first time was higher than the traditional blind procedure group, with statistically significant difference （ P 〈 0. 05 ）. CONCLUSION： Ultrasound combined with DSA guided cannulation of the intemal jugular vein is superior to the traditional anatomic landmarks technique.
