From 1987 until 1992, 16 triplets and 2 quadruplets were studied by pulsed Doppler ultrasound between 17 and 36 weeks of gestation. A resistance index (RI) of the foetal aorta and umbilical artery above the 95th percentile was considered pathological. Elevated RI-values of the umbilical artery as compared to the A. cerebri media were indicative of circulatory centralisation. Intrauterine growth retardation (IUGR) was found in 9 (16%) foetuses, discordant growth occurred in 7 (39%) pregnancies. 41 (73%) of 56 foetuses survived in good health. Four of 7 foetuses with pathological Doppler findings died. The three survivors were markedly retarded. Four of 6 cases of intrauterine endangered foetuses were detected by Doppler sonography. The diagnosis of IUGR or discordant growth was based more frequently on pathological Doppler findings than on biometry and improved upon by combinations of both methods. Doppler sonography proved to be an important complementary method in the monitoring of high-grade multiple pregnancies.

Cancer in pregnancy has an incidence of approximately 1:1000, and cases of sarcoma in pregnancy are rare, with only a few described in the literature. This case report describes a 32-year-old pregnant woman who noticed an approximately 3.0 cm nodule on her left flank in the second trimester of pregnancy.

Background: Gastro-esophageal variceal hemorrhage (GEVH) is one of the major causes of life-threatening gastrointestinal bleeding in children. Medical, endoscopic, angiographic, and surgical interventions can be utilized in treatment. In this case report, we describe partial splenic artery embolization for refractory GEVH due to portal vein thrombosis.

The twin reversed arterial perfusion (TRAP) sequence is a rare complication associated with monochorionic twins. It is characterized by blood flow from the umbilical artery of the normal (pump) twin to the umbilical artery of the abnormal (acardiac) twin via artery-to-artery anastomosis. This condition is associated with 100% mortality in the acardiac twin and a high rate of perinatal morbidity and mortality in the pump twin, primarily due to intrauterine hypoxic injury, heart failure, and prematurity.

Objectives: To produce standards of references for quality control and assess the reproducibility of fetal ultrasound Doppler measurements commonly used for blood flow assessment in fetal growth.
Methods: Women with singleton normal pregnancies were prospectively recruited at University College London Hospital, UK, between 24 and 41 weeks. Umbilical artery (UA), middle cerebral artery (MCA), and their pulsatility indices (PI), resistance indices (RI) and ratios such as cerebro-placental (CPR) and umbilical cerebral ratio (UCR) were obtained twice by two sonographers in training or after completion of training, blind to each other's measurements.
