Surgical Retrieval of a Transected Dual-Lumen Umbilical Venous Catheter Remnant that Was Misplaced in the Aorto-Iliac Artery of a Pre-Term Neonate.

Vasc Endovascular Surg 2022 May 17;56(4):428-431. Epub 2022 Feb 17.

Department of Vascular Surgery, 4965The Royal Free London NHS Foundation Trust, London, UK.

Despite rare, retrieving detached umbilical venous catheter (UVC) remnants from central vessels in neonates is challenging due to their small body habitus and vessels with high risk of vascular injury and thrombosis and often associated comorbidities. We report a challenging surgical retrieval of a UVC remnant from the aorto-iliac artery of a pre-term neonate. An attempted UVC insertion into a pre-term neonate was complicated by misplacement and detachment of a 4 cm remnant into the infra-renal abdominal aorta and left iliac artery. Read More

Umbilical venous catheterisation: emergency central venous access which saves lives in coarctation of the aorta.

BMJ Case Rep 2021 Nov 11;14(11). Epub 2021 Nov 11.

Newborn & Paediatric Emergency Transport Service, Sydney Children's Hospitals Network, Sydney, NSW, Australia

We describe a 9-day-old baby with coarctation of the aorta who required urgent resuscitation including intubation and cardiac compressions. Despite the commencement of prostaglandin E1 (PGE) to reopen the ductus arteriosus via the intraosseous route, postductal saturations remained unrecordable for a further 45 min. Within 3 min of administration of PGE via an umbilical venous catheter (UVC), saturations were recordable at 92%. Read More

Ultrasound guided percutaneous catheterization of the brachiocephalic vein by small caliber catheter: An alternative to epicutaneo-caval catheter in newborn and premature infants.

J Vasc Access 2021 Aug 8:11297298211034311. Epub 2021 Aug 8.

Pediatric and Neonatal Intensive Care Unit, Bicêtre Medical Centre, Paris Saclay University, AP HP, Le Kremlin Bicêtre, France.

Background: Umbilical Venous Catheter (UVC) and Epicutaneo-Caval Catheters (ECC) are reference catheters in the neonatal period. However, many factors such as the corpulence of neonates, poor venous capital, and anatomical variants can complicate ECC insertion or make it impossible. In newborns with failed ECC insertion, we developed an hybrid technique that combines the insertion of a long-lasting silicone or polyurethane small caliber catheter, usually used as a ECC in newborns, with the ease and speed of ultrasound guided puncture of the brachiocephalic vein (BCV).
