Abstract:
A fibrin sheath with central venous occlusion is a common complication after central venous catheterization, and these patients often experience catheter dysfunction. A calcified fibrin sheath can cause a catheter to be stuck, and typically necessitates catheter removal or replacement. From another point of view, a calcified fibrin sheath can be seen in ultrasound and computed tomography, and the original fibrin sheath channel between the internal jugular vein and the atrium is unusually strong. When central vein occlusion occurs, the remnant calcified fibrin sheath of the internal jugular vein can be punctured under ultrasound guidance, allowing the guidewire to enter the atrium directly through the fibrin sheath. Here, we report a case in which we achieved easy recanalization of a long segment occluded superior vena cava by puncturing the remnant calcified fibrin sheath of the internal jugular vein.
摘要:
中心静脉阻塞的纤维蛋白鞘是中心静脉导管插入术后的常见并发症,这些患者经常经历导管功能障碍。钙化的纤维蛋白鞘会导致导管被卡住,并且通常需要移除或更换导管。从另一个角度来看,在超声和计算机断层扫描中可以看到钙化的纤维蛋白鞘,颈内静脉和心房之间的原始纤维蛋白鞘通道异常坚固。当发生中央静脉阻塞时,在超声引导下可以穿刺颈内静脉残余的钙化纤维蛋白鞘,允许导丝直接通过纤维蛋白鞘进入心房。这里,我们报告了一个病例,通过穿刺颈内静脉的残余钙化纤维蛋白鞘,使一个长段闭塞的上腔静脉容易再通。
