Renal vein thrombosis in neonates with acute kidney injury; using ultrasound to facilitate early detection

Renal vein thrombosis (RVT) usually presents in the first month of life and is associated with acute kidney injury (AKI). This case series examines five cases of RVT that occurred in a large tertiary neonatal intensive care unit in the northwest of England between 2019 and 2022.

Key points
  1. Renal vein thrombosis usually presents in the first month of life.
  2. Renal vein thrombosis is associated with acute kidney injury.
  3. The haemostatic system differs with age and the concentration of anticoagulants such as antithrombin, proteins C and S are low at birth.
  4. Data implies that there should be a higher index of suspicion.
  5. Earlier Dopplers and ultrasound scans should be carried out.

Non-invasive use of inhaled nitric oxide for neonatal pulmonary hypertension
Inhaled nitric oxide (iNO) is a selective pulmonary vasodilator used as primary treatment for babies with persistent pulmonary hypertension of the newborn (PPHN). Evidence shows that its use reduces mortality and need for extracorporeal membrane oxygenation (ECMO).1 iNO is normally commenced at a concentration of 20 parts per million (ppm) when babies have been intubated and ventilated and then slowly weaned off prior to extubation.
