主动脉血栓形式是脐动脉插管术一频发的严重合并症。本文总结了四年来应用超声波和主动脉造影确诊的主动脉血栓20例。每例均在生后第一天经脐动脉插入聚氯乙烯导管。于生后2～35天发生主动脉血栓。脐动脉导管机械损伤主动脉血管内皮,暴露了胶原纤维,使血小板粘着吸附,最终而成血
Aortic thrombosis is a serious complication of umbilical artery catheterization. This article summarizes the four years of application of ultrasound and aortic angiography confirmed 20 cases of aortic thrombus. Each case was inserted into the PVC catheter through the umbilical artery on the first day after birth. Aortic thrombosis occurs 2 to 35 days after birth. Umbilical arterial catheter injury to the aortic vascular endothelium exposed collagen fibers, so that platelet adhesion and adsorption, and eventually into blood
