目的：探讨股静脉半永久留置导管在维持行透析（MHD）患者中的临床应用。方法：将10例行股静脉半永久双腔导管留置的患者，与同期颈内静脉双腔导管留置患者52例做对比，观察两组患者的导管使用寿命、并发症、透析血流量及透析充分性等指标。结果：股静脉组留置时间>6个月者为70.0%（7/10），颈内静脉留置时间>6月者为86.5%（45/52）；两组间导管感染和导管功能不良等并发症方面并无明显统计学差异（p>0.05）；导管血流量和透析充分性在两组间亦无明显统计学差异(p>0.05)。结论：在血管条件不佳或一般情况较差、留置颈内静脉困难的透析患者中，股静脉留置半永久性导管亦可以是一种较为理想的选择。

Objective Discussion the clinical application of the semi- permanent double- lumen vein cuffed-tunneled catheters in maintaining hemodialysis (MHD) patients. Methods 10 cuffed- tuneled catheters were indwelled in femoral vein as femoral vein group and the other 52 catheters were indwelled in internal jugular vein as jugular vein group in the same period.The catheter survival time,related complications of catheters, mean blood flow during hemodialysis and Kt/V in the two groups were observed. Results There was 70.0%(7/10) catheters sustainable using over 6 months in femoral vein group, while 86.5%(45/52) catheters in jugular vein group. There were no significant differences between the two groups in catheter infection and catheter dysfunction aspects (P＞0.05). Catheter blood flow and dialysis adequacy also have no significant differences between the two groups (P＞0.05). Conclusions Semi-permanent femoral vein double-lumen catheter can also be an ideal choice, when the patients have poor vascular conditions or poor general conditions, or have difficult to be indwelled internal jugular vein catheter.
