The risk of thrombosis related to peripherally inserted central catheters (PICCs) is a well-known complication. A study was conducted to compare thrombosis rates associated with the old technique of inserting PICCs by visualizing veins in the antecubital fossa, using anatomical landmarks and palpation versus using ultrasound guidance to locate veins in the upper arm. The findings from data collected on 538 patients included a significant decline in the thrombosis rates, as thrombosis decreased from 9.3% with the palpation method to 1.9% with the ultrasound method, and successful PICC placements by registered nurses increased from 76.9% when using the old method to 98.9% when using ultrasound guidance.
与外周静脉穿刺中心静脉导管（PICC）相关的血栓形成风险是一种众所周知的并发症。开展了一项研究，比较通过可视化肘前窝静脉、使用解剖标志和触诊来插入PICC的旧技术与使用超声引导在上臂定位静脉这两种方法的血栓形成率。收集的538例患者的数据结果显示，血栓形成率显著下降，因为血栓形成率从触诊法的9.3%降至超声法的1.9%，并且注册护士成功放置PICC的比例从使用旧方法时的76.9%增至使用超声引导时的98.9%。
