摘要
目的 探讨超声造影(CEUS)技术在经外周静脉穿刺中心静脉置管(PICC)相关性血栓诊断中的应用价值.方法 2015年8月至2016年8月,在天津医科大学总医院普通外科超声介入室对23例临床怀疑PICC相关性血栓但常规超声不能确诊的患者行CEUS检查,比较常规超声和CEUS两种检查方法的血栓检出情况,总结分析CEUS的诊断价值.结果 CEUS在腋静脉和肱静脉处的血栓检出例数多于常规超声检查,差异有统计学意义(P<0.05);CEUS检查可对存在彩色外溢、低流速下无明显血流信号、临床症状严重等PICC相关性血栓可疑者做出进一步诊断,明确血栓形成情况.结论 对于临床怀疑PICC相关性血栓但常规超声难以确诊者,可进一步实施CEUS检查,其过程安全,结果可靠,值得推广应用.
Objective To investigate the application effect of contrast-enhanced ultrasound in the diagnosis of peripherally inserted central catheter (PICC) associated thrombosis. Methods Twenty three cases of PICC with highly suspected thrombosis underwent conventional Doppler ultrasound and contrast-enhanced ultrasound (CEUS), the two methods of inspection were then compared for detection in different parts of the upper limb veins. Results The number of thrombosis in axillary vein and brachial vein detected by CEUS was greater than that detected by conventional Doppler ultrasound(P<0.05). CEUS can make further diagnosis of PICC associated thrombosis in the presence of color spillover, low blood flow rate and severe clinical symptoms. Conclusion The application of contrast-enhanced ultrasound in the accurate diagnosis of PICC related thrombosis is safe and reliable, it is worthy of clinical application.
