Contrast-enhanced ultrasound performance in predicting blunt splenic injuries requiring only observation and monitoring

Abstract

Aims: To assess contrast enhanced ultrasound (CEUS) performance in the prediction of non-operatively managed blunt spleen injuries requiring only observation and monitoring during follow-up and to evaluate if CEUS accuracy was higher than conventional ultrasound (US) in this field.Material and methods: In 112 hemodynamic stable blunt spleen trauma patients, CEUS was performed for follow-up after computed tomography evaluation in the emergency department. CEUS and US performance were assessed considering as true negative cases patients that had not underwent interventional or surgical treatment during follow-up and were assessed as negative for splenic complications respectively by CEUS or US examinations.Results: CEUS showed sensitivity of 100%, specificity of 96.1%, positive predictive value of 69.2%, negative predictive value of 100.0% and accuracy of 96.4%. CEUS showed a significantly higher accuracy than conventional US (p=0.013).Conclusions: CEUS is a very useful imaging modality during follow-up of blunt splenic trauma non-operatively managed, allowing an efficientprediction of splenic injuries requiring only observation and monitoring during follow-up.

Various aspects of Contrast-enhanced Ultrasonography in splenic lesions – a pictorial essay

“…Although contrast-enhanced CT remains the primeline investigation in politrauma patients, studies proved the utility of CEUS in the diagnosis, minimally invasive therapy, and follow-up of minor, blunt trauma, especially in children and young women [8][9][10]. Due to its arterial inhomogeneity and long-lasting contrast enhancement, the spleen is examined after the kidneys and liver, the lesions being clearly visible in the venous and late phase.…”

Comparison of voiding vesicoureteral urosonography with fluoroscopic voiding cystourethrography in children with vesicoureteral reflux

“…Vesicoureteral reflux (VUR) may give rise to repeated urinary tract infections in children to a certain extent, given the close correlation between the two. 11 , 12 If no timely diagnosis is made, the normal growth and development of children may be affected. 13 Currently, diagnostic techniques for VUR have been continuously explored and improved.…”

“…In another study, CEUS was performed at 12, 24, and 48 h after mild liver and spleen trauma to ensure a safe discharge from ICU to the general ward. 28 What's more, Tagliati et al published three researches with the same patients with splenic trauma in 2019, [29][30][31] patients For personal use only.…”

But no change in injury was observed within three days post-trauma, and CEUS was applied to diagnose delay active hemorrhage or assess healing time of solid organ injuries in these studies.…”
