Indwelling femoral venous catheters were prospectively studied by ultrasonography to define the frequency and evolution of inferior vena cava (IVC) thrombosis. IVC thrombosis was identified in six of 56 catheters (54 children). Only one patient with a positive ultrasound scan had clinical signs of thrombosis. All children with IVC thrombosis had had catheters in place for over six days. It is recommended that either the femoral central venous catheters are routinely changed at six days or ultrasound studies are routinely performed twice a week in all patients with catheters in situ for six or more days and that the catheter is removed immediately if evidence of thrombosis appears.
通过超声对留置股静脉导管进行前瞻性研究,以确定下腔静脉(IVC)血栓形成的频率和演变情况。在56根导管(54名儿童)中有6根发现了IVC血栓形成。只有一名超声扫描呈阳性的患者有血栓形成的临床体征。所有发生IVC血栓形成的儿童其导管留置时间均超过6天。建议要么在6天时常规更换股中心静脉导管,要么对所有导管留置6天或更长时间的患者每周常规进行两次超声检查,并且如果出现血栓形成的迹象应立即拔除导管。
