Abstract:
The use of umbilical artery catheters is common in Neonatal Intensive Care Units, especially in low and very low birth weight neonates. Rarely, these can break or fracture, leading to a retained fragment, which can embolize or cause thrombosis. We pre sent a case of a very low birth weight, premature neonate, 940 grams, with a retained umbilical artery catheter that led to bilateral lower extremity ischemia. A laparotomy with aortotomy was per formed for retrieval of the catheter. Chronic occlusion of the aorta with collateralization is a long-term complication associated with this case.

Fetal Circulation
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
