Livedo racemosa (LRac) refers to violaceous, red, or blue netlike mottling of the skin in an irregular pattern caused by circulatory abnormalities. Central venous catheters (CVC) are widely used in neonates who require intensive care to offer steady intravenous access. CVCs are covered with a hydrophilic polymer gel that reduces friction between the sheath and the vessel wall, thereby minimizing vascular spasm, irritation, and aneurysm formation. However, the introduction of foreign material into the vein carries a risk of embolization. Recently, LRac was reported as a cutaneous manifestation of hydrophilic polymer gel embolization (HPE) in adults. We present a case of LRac in a newborn that developed following CVC insertion and resolved spontaneously after the catheter was removed.

与新生儿中心静脉导管使用相关的总状青斑

总状青斑 (LRac) 是指由循环异常引起的不规则图案的紫色、红色或蓝色网状皮肤斑点。中心静脉导管 (CVC) 广泛用于需要重症监护以提供稳定静脉通路的新生儿。CVC 覆盖有亲水性聚合物凝胶，可减少护套与血管壁之间的摩擦，从而最大限度地减少血管痉挛、刺激和动脉瘤形成。然而，将异物引入静脉会带来栓塞的风险。最近，LRac 被报道为成人亲水性聚合物凝胶栓塞 (HPE) 的皮肤表现。我们介绍了一个新生儿 LRac 病例，该病例在插入 CVC 后发生，并在导管拔除后自行消退。
