Discriminative imaging of maternal and fetal blood flow within the placenta using ultrafast ultrasound
Being able to map accurately placental blood flow in clinics could have major implications in the diagnosis and follow-up of pregnancy complications such as intrauterine growth restriction (IUGR). Moreover, the impact of such an imaging modality for a better diagnosis of placental dysfunction would require to solve the unsolved problem of discriminating the strongly intricated maternal and feta...
متن کاملThe dynamic placenta: I. Hypothetical model of a placental mechanism matching local fetal blood flow to local intervillus oxygen delivery.
The placenta can be severely infarcted and yet return well oxygenated blood in spite of the potential shunt paths produced. Optimisation of oxygen transport by some form of local flow matching has been suggested, either via a direct action of hypoxia on subchorial vessels, or indirectly by syncytiotrophoblastic metabolic products. Using casts of cotyledonal vessels and software modelling, a mec...
متن کاملBRIEF REVIEW Distribution and Regulation of Blood Flow in the Fetal and Neonatal Lamb
AFTER the postnatal mammalian circulation has been established, blood flows serially from the systemic veins through the right side of the heart to the lungs, then to the left atrium and ventricle, which ejects the blood into the aorta to be distributed to the body, after which it returns to the systemic venous system. Apart from a small amount of coronary venous blood which enters the left ven...

متن کاملEffects of angiotensin II on the blood flow and its distribution in fetal lambs.
We studied the effects of intravenous infusion of angiotensin II on the circulation of the fetus in lambs in utero through chronically maintained intravascular catheters. Angiotensin II infused in doses of 29-280 ng/min per kg fetal weight resulted in an increase in plasma angiotensin II from a control value of 87 +/- 17 to 341 +/- 129 (mean +/- SE) pg/ml; these levels are similar to those obse...
