- Abstract
Contrast-enhanced ultrasound (CEUS) has developed from the necessity to increase the sensitivity of standard ultrasound in the diagnosis of intraabdominal lesions, especially of hepatic tumors. Microbubble contrast agents allowed the descriptions of the hepatic lesions and other tumors, through their behaviors in three vascular phases - arterial phase, venous phase and parenchyma phase - and so, they can asses a certitude diagnostic with a sensitivity compared to CT or MRI exams. Objectives. In this study, we proposed to evidence the advantages of contrast enhanced ultrasound in oncologic surgery. Method. Eleven contrast enhanced ultrasound were performed in Surgery Department I of the “Prof. Dr. Alex. Trestioreanu” Institute of Oncology Bucharest, with Toshiba Nemio XG and Hitachi Aloca. Contrast enhanced used was Sonovue, a contrast enhanced of second generation. The lesions evaluated by contrast enhanced ultrasound usually have a perfusion pattern and acoustic amplification relative typical in vascular phases, which helped us to asses the diagnosis. Results. With contrast enhanced ultrasound, it was evaluated the response at RFA therapy of hepatic metastases in 6 patients known with digestive neoplasm. In two patients known with abdominal neoplasm, using contrast enhanced ultrasound, there were evidenced hepatic lesions which CT or MRI didn't discover. In another two patients (one with prostatic nodular lesions, and the other with pancreatic lesions), the contrast enhanced ultrasound could establish with certitude that these lesions were benign. Conclusions. Contrast enhanced ultrasound is a safe and efficient method to explore the oncological surgical pathology. With contrast enhanced ultrasound, the diagnostic is rapid, with low costs compared with CT or MRI evaluation, and with the possibility to have a therapeutic attitude more quickly.
