ABSTRACT
BACKGROUND: Umbilical arterial catheterization is a common procedure performed on critically ill neonates, especially those with extreme prematurity. Various complications have been described following umbilical artery catheter (UAC) placement including thrombosis, embolism, vasospasm, vascular perforation, hemorrhage, and infection. However, treatment of these complications is challenging due to the small size of this very fragile subset of patients. METHODS: A 3-day old extremely preterm infant was referred to our institution for percutaneous removal of a fragmented and embolized umbilical arterial catheter. RESULTS: Catheter retrieval was successful via a carotid approach utilizing techniques from percutaneous closure of PDA in preterm infants and trans-carotid access for PDA stent and aortic interventions. CONCLUSION: This case report describes the successful percutaneous retrieval of an embolized UAC fragment in an extremely preterm infant, the smallest documented in literature to date.
ABSTRACT
AVP ll and ADO ll AS devices are effective and safe for percutaneous PDA closure. Residual shunt and serious complications are uncommon Mild LPA stenosis and device embolization are the most frequent complications reported.

Neonatal percutaneous carotid access is a safe technique that compares favorably to neonatal surgical carotid access. Mid-term ultrasound and angiographic follow after percutaneous carotid access shows 100% vessel patency rate with no severe stenoses or aneurysms detected. Mild stenosis (<12%) is frequent at follow up (35%), the clinical significance of which is unknown.

Catheter access to the "native" atria is limited after extra-cardiac Fontan palliation of univentricular cardiac defects Catheter access to the atria is necessary to percutaneously treat acquired abnormalities after extra-cardiac Fontan palliation Direct trans-thoracic atrial access and extra-cardiac conduit puncture is technically straightforward and allows for novel catheter interventions.
