Neonates with prolonged hospitalization often require PICCs. The concern for PICC-related complications, including venous thrombosis, infection, catheter migration and breakage, often prompts Doppler ultrasound (US) evaluation. However, peri-catheter thrombus in a neonate can be challenging to evaluate, as the accessed peripheral veins in neonates are small, some less than 1mm in luminal diameter. Small-bore catheters may occupy the entirety of the vessel lumen, which can produce absence of peri-catheter flow, which is confounding for thrombus. This distinction has implications for hematologic management.
