“…More specific spinal and pelvic fractures, diaphragmatic ruptures, pancreatic or adrenal injuries, vascular injuries and finally bowel and mesenteric lacerations may well be under-diagnosed or not even visualised [17]. To overcome this disadvantage, contrastenhanced ultrasound is now recommended as a promising technique to help visualise solid organ injuries, especially if they involve the liver or the spleen [26].…”

Findings and limitations of focused ultrasound as a possible screening test in stable adult patients with blunt abdominal trauma: a Greek study

Our objective is to underline the place of FAST (focus assessment by sonography for trauma) ultrasonography (US) in the investigation of blunt abdominal trauma. We retrospectively examined the ultrasound findings in 1,999 haemodynamically stable adult patients. These people were admitted to the emergency room (ER) for possible blunt abdominal trauma. All were stable at admission and a FAST ultrasound examination was made. Initial findings were compared with the clinical course after at least 24 h of observation time and CT results. Among the 1,999 US examinations, abnormalities were found in 109 (5.5%) cases. Among them, 102 had free peritoneal fluid, and in 58 examinations, ruptures, lacerations or haematomas were demonstrated. Despite its limitations, such as in cases involving uncooperative patients, excessive bowel gas, obesity and empty bladder, the FAST technique seems to be an accurate method to evaluate the possibility of abdominal blunt trauma in stable patients. Because of the high negative predictive value of the FAST technique in stable patients with blunt abdominal trauma, we recommend that a stable patient with negative ultrasound results at admission remain under close observation for at least 12 or preferably 24 h before being discharged.

“…CEUS is significantly more accurate in identifying posttraumatic injury to abdominal solid organs, reaching a sensitivity almost equal to that of CT [16,17]. The use of CEUS has recently been included in the guidelines issued by the European Society of Ultrasound in Medicine and Biology (EFSUMB) on the study of abdominal trauma if CT is not available or contra-indicated for previous allergic reactions to iodinated contrast agent or if CT is not conclusive due to artifacts.…”

KEYWORDSUltrasonography; Contrast agent; Abdominal trauma.Abstract Introduction: To evaluate the use of contrast-enhanced ultrasonography (CEUS) in patients with blunt abdominal trauma. Materials and methods: A total of 133 hemodynamically stable patients were evaluated using ultrasonography (US), CEUS and multislice Computer Tomography (CT) da eliminare. Results: In 133 patients, CT identified 84 lesions: 48 cases of splenic injury, 21 of liver injury, 13 of kidney or adrenal gland injury and 2 of pancreatic injury. US identified free fluid or parenchymal abnormalities in 59/84 patients positive at CT and free fluid in 20/49 patients negative at CT. CEUS revealed 81/84 traumatic injuries identified at CT and ruled out traumatic injuries in 48/49 negative at CT. Sensitivity, specificity, positive and negative predictive values for US were 70.2%, 59.2%, 74.7% and 53.7%, respectively; for CEUS the values were 96.4%, 98%, 98.8% and 94.1%, respectively. Conclusions: The study showed that CEUS is more accurate than US and nearly as accurate as CT, and CEUS can therefore be proposed for the initial evaluation of patients with blunt abdominal trauma.Sommario Introduzione: Descrivere l'impiego dell'ecografia con mezzo di contrasto (CEUS) nella valutazione dei pazienti con trauma chiuso dell'addome. Materiali e Metodi: 133 pazienti con trauma addominale chiuso emodinamicamente stabile sono stati esaminati con ecografia (US), CEUS e Tomografia Computerizzata multistrato (TC) da eliminare. Risultati: I 133 pazienti avevano alla TC 84 lesioni, di cui 48 spleniche, 21 epatiche, 13 renali o dei surreni e 2 del pancreas. L'US ha identificato versamento libero o alterazioni parenchimali in 59/84 pazienti positivi alla TC e versamento libero in 20/49 pazienti negativi alla TC. La CEUS ha riconosciuto 81/84 lesioni traumatiche identificate dalla TC e ha escluso lesioni traumatiche in 48/49 pazienti negativi alla TC. Sensibilità, specificità, valore predittivo positivo e negativo per l'US sono stati rispettivamente 70.2%, 59.2%, 74.7% e 53.7%; per la CEUS sono stati 96.4%, 98%, 98.8% e 94.1%. Conclusioni: Lo studio ha dimostrato che la CEUS ha una accuratezza diagnostica maggiore dell'US e quasi sovrapponibile alla TC e può quindi essere proposta nella valutazione iniziale del paziente traumatizzato. ª

“…Ultrasound evaluation was performed by a BK Medical Pro Focus TM (Herlev, Denmark), which is currently the only US-based ultrasound machine for liver-specific, harmonic-pulsed, non-destructive, contrast-enhanced microbubble evaluation. Single bolus (1cc) of Definity TM (Lantheus Medical ImagingBldg., Billerica, MA) contrast [7] was then administered per established intra-operative protocol to evaluate the known hepatic lesions and to evaluate for any other lesions not seen on initial ultrasound as described in the literature [7,8].…”
