Introduction: Previously, all admitted neonates to our tertiary Neonatal Unit, University of Szeged, had a cranial and abdominal ultrasound performed as part of their care.
Objective: To analyze the findings and to evaluate the effectiveness of the universal ultrasound screening.
Method: Results of cranial and abdominal ultrasound imaging performed in our Unit between 1st January 2014 and 31st December 2015 were analyzed retrospectively. Abnormalities found during the screening scans were studied further and assessed until discharge and during the first 2 years. All imagings were performed by a radiologist.
Results: During the examined 2 years, 579 neonates were admitted (gestational age mean 34.2 weeks [23-41, SD ± 4.04]), abdominal ultrasound was performed in 562 (97%) and cranial ultrasound in 560 (97%) babies, on the 3.6th day of life at an average (0-18, SD ± 2.24). Of all abdominal ultrasound scans, 87% (n = 488) was carried out as screening, and the found abnormalities in 140 (29%) of the cases: renal pelvic dilatation (n = 67 [47.9%]), free abdominal fluid (n = 17 [12.1%]), echogenic kidneys (n = 13 [9.3%]), congenital abnormalities of the kidney and urinary tract (n = 9 [6.4%]), abnormalities of the liver, bile system, adrenal gland [n = 14 [10%]). The screening identified 4 (0.8%) neonates with renal abnormilaties requiring surgical correction. In regards of renal abnormalities, we observed male (p = 0.18) and left sided (p = 0.54) predominance. Screening cranial ultrasound was performed in 65% (n = 362) of all neonates, discovering 51 (14%) anomalies: plexus chorioideus cyst (n = 21 [41%]), plexus chorioideus hemorrhage (n = 9 [17.6%]), mild ventricular asymmetry (n = 8 [15.7%]), subependymal hemorrhage (n = 5 [9.8%]), abnormalities of the periventricular area (n = 4 [7.8%]), colpocephaly, hydrocephalus externus, echogenic meninx and thalamic nodule [n = 1-1 (1.9-1.9%)].
Conclusion: Abdominal ultrasound screening discovered renal abnormalities and umbilical line complications as clinically relevant findings. However, a small number of renal abnormalities identified by screening required surgical intervention. Further studies are needed to identify possible risk groups to develop more efficient screening strategy to decrease the number of screened babies for 1 relevant finding (number to screen). Cranial ultrasound screening did not identify any abnormalities that needed intervention. We can not recommend universal cranial ultrasound screening based on our results.
