【摘要】目的 探讨深静脉导管纤维蛋白鞘彩色多普勒超声的影像学特点。方法 自2010年4月～2011年1月，本研究对28例使用深静脉临时导管的血液透析患者进行了拔管前彩色多普勒超声检查，并对其中13例患者在拔管后1个月再次进行超声检查，观察导管纤维蛋白鞘的情况。结果 28例患者中，26例患者超声可见导管表面纤维蛋白鞘形成，检出率为92.9%，追踪随访13例患者，拔管后1个月时超声仍可见静脉插入点处纤维蛋白鞘膜状物原位存在。28例患者中15例拔出纤维蛋白鞘，拔出率为53.6%。结论 彩色多普勒超声可观察到纤维蛋白鞘特异性影像学表现，是1种临床易于操作和掌握的观察、诊断纤维蛋白鞘的方法，有利于血液透析患者深静脉导管功能的维护。

【Abstract】 Objective To explore the iconographic characteristics of deep venous catheter related fibrin sheath using color Doppler ultrasonography. Methods During the period of April 2010 to January 2011, 28 hemodialysis patients with temporary catheter were examined by color Doppler ultrasonography before removing the catheter, and thirteen of them were re-examined after the removing for one month. Results In the 28 patients, 26 (92.9%) showed the development of fibrin sheaths by color Doppler ultrasonography. Fibrin sheath at the puncture site was still found in 13 patients re-examined one month after discontinuing the catheterization. Fibrin sheaths were taken out during pulling out of the catheter in 15 of the 28 (53.6%) patients. Conclusion Color Doppler ultrasonography can obtain specific iconography of fibrin sheath following deep venous catheterization. This relatively simple method is useful for the surveillance of deep venous catheter function, and is suitable for the observation and diagnosis of deep venous catheter related fibrin sheath.
