Ureteral injuries are uncommon but serious complications of laparoscopically-assisted vaginal hysterectomy. The ureter is particularly at risk for inadvertent injury when the cardinal-uterosacral ligament complex is coagulated and divided below the uterine vessels. We present two recent cases which describe the application of transabdominal ultrasound including color Doppler mapping in the diagnosis of ureteral injury after laparoscopically-assisted vaginal hysterectomy. Transabdominal ultrasound including color Doppler mapping has great diagnostic potential as a method for non-invasive evaluation of post-operative ureteral conditions. Ultrasonic triads (absence of a ureteric jet, ascites, and the presence or absence of hydronephrosis) are capable of differentiating diagnosis of complete, partial, or nonobstructive surgical ureteral injuries.

A case of mixed intrahepatic arteriovenous shunts in a fetus diagnosed at 35 weeks' gestation is presented. Color Doppler ultrasonography in the fetal liver demonstrated complicated vascular connections fed by the hepatic arterial branches and drained into the portal and middle hepatic veins. Pulsed Doppler ultrasonography identified a high cardiac output state by the detection of increased flow velocities of the great vessels. The contribution of Doppler ultrasonography to hemodynamic changes is highlighted. The management is briefly discussed. [ABSTRACT FROM AUTHOR]

Fetal cardiac hemangioma is rarely diagnosed prenatally. We present here a fetus with such a tumor diagnosed at 28 weeks' gestation. With the use of fetal echocardiography, a mixed echogenic mass protruding outward from the right atrial wall was observed. Moderate amounts of pericardial effusion were also found. Although no apparent blood flow signal was detected in the mass, fetal echocardiography showed signs suggestive of a hemangioma. Differential diagnosis, management and prognosis are discussed.
