CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishINTRODUCTION: We describe the use of contrast-enhanced ultrasound (CEUS) in the diagnosis of delayed splenic vascular injury (DSVI) and active extravasation (DAE) during spleen injury follow-up. CEUS might be used instead of contrast-enhanced computed tomography (CECT) during spleen injury follow-up in order to reduce radiation exposure. OBJECTIVE: Assess diagnostic comparability between CEUS and CECT in the evaluation of DSVI and DAE during spleen injury follow-up. SUBJECTS AND METHODS: A total of 139 trauma patients (101 males, 38 females; mean age 48.6 years) with CECT diagnosed spleen injury were prospectively evaluated. They performed CEUS and CECT follow-up. All CEUS studies were performed using the same ultrasound scan, convex probe, mechanical index and ultrasound contrast agent dose. Twelve patients performed digital subtraction angiography (DSA) during follow-up, and the diagnostic performance comparability between CEUS and DSA was evaluated. RESULTS: CEUS showed 17 delayed spleen injury complications, and in 122 patients no complication was suspected. CECT diagnosed 16 delayed spleen injury complications in these 17 patients and showed a small DSVI in another patient. A total of 122 follow-up CT scans were negative. CEUS and CECT diagnostic comparability was 98.6%. Compared to DSA, CEUS showed a sensitivity of 100% and a positive predictive value of 91.7%. CONCLUSIONS: CEUS can be used during spleen injury follow-up instead of CECT. Positive CEUS examinations could perform CECT and, when necessary, DSA in order to confirm and treat spleen injury complications.
