摘要：

Pericatheter thrombus calcification is a complication that arises due to central venous catheter insertion and is particularly rare in peripherally inserted central catheters (PICCs). In this case report, we reviewed the clinical course of two neonates experiencing thrombus calcification. The first case involved a male neonate weighing 445 g. His PICC dwelt in the superior vena cava for over 49 days. Although a radiograph after removal did not show any silhouette, subsequent radiographs and CT depicted a catheter-like outline. Percutaneous intravascular retrieval was performed to salvage the object. Pathological examination revealed it to be a calcified cast. The calcified thrombosis was successfully dissolved with 6 months of warfarin therapy. The second case involved a male neonate weighing 534 g. After PICC removal, a catheter-like structure was shown on ultrasonograms. It was determined that invasive procedures were unnecessary for diagnosing the calcified thrombosis based on experience with the first case.
