RESUMO
28 patients with blunt abdominal trauma were evaluated by ultrasonography. The diagnosis were confirmed at operation in 20 patients and clinical follow-up in 8. There was one false negative. In 27 patients, the demonstrated abnormalities were intraperitoneal fluid, hepatic, splenic or renal hcmatoma, perisplenic fluid, intrarenal fluid (urinoma) and pleural effusion. It is concluded that ultrasonography is valuable in the diagnosis and follow-up of blunt abdominal traumas.
RESUMO
36 cases of primary liver cancer and 17 cases of benign spaceoccupying lesions were studied with color Doppler flow imaging (CDFI) and ultrasonic pulsed Doppler. Among the 36 cases of primary hepatic carcinoma, abnormal color blood flow around tumor nodules was observed in 34 cases (94.4%), and blood flow within the tumors was seen in 30(83.3%). When the blood flow was demonstrated, it showed a pulsating wave pattern in all cases. The blood flow within the tumors also showed a pulsating wave pattern in all but one. These characteristics were found in most of the primary hepatic carcinomas but not in benign space-occupying lesions. So color Doppler flow imaging is useful in the differential diagnosis of hepatic tumors.
