The relationship between Doppler indices from inferior vena cava and hepatic veins in normal human fetuses.
This study was conducted to determine the gestational age-related reference range of the preload index [peak velocity during atrial contraction (A)/peak velocity during ventricular systole (S)] for the inferior vena cava (IVC), the right hepatic vein, the middle hepatic vein and the left hepatic vein. The slope and the intercept of the regression line for each preload index were compared among ...
متن کاملAgenesis of Ductus Venosus Presenting with Dilated Inferior Vena Cava with Favorable Outcome
The ductus venosus regulates the distribution of oxygen and placental nutrients by restricting the centralization of blood flow in fetal circulation. The ductus venosus is a small vein transmitting oxygen-rich blood from the umbilical vein to the fetal heart.. Increasing numbers of case reports are being published about ductus venosus agenesis with cardiac structural abnormalities, other malfor...
متن کاملINFERIOR VENA CAVA THROMBOSIS IN A PATIENT WITH ESSENTIAL THROMBOCYTHEMIA
Essential thrombocythemia is a chronic myeloproliferative disorder characterized by a sustained proliferation of megakaryocytes, which leads to increased numbers of circulating platelets. Hemorrhagic and/or thrombotic episodes are frequent, and thrombosis of both veins and arteries may develop. Vessels in unusual sites may be involved, e.g., the hepatic veins, mesenteric veins, and the dig...
متن کاملThe efficacy of inferior vena cava diameters and the jugular vein in assessing fluid resuscitation
Objective: Fluid resuscitation is necessary in almost all critical patients. The central venous pressure (CVP) is a well-established method of assessing resuscitation. Recently, there have been attempts to investigate less invasive methods like the diameters of inferior vena cava (IVC) or the jugular vein. We aimed to investigate this method in our research.Methods: Seventy eight critical...
متن کاملI-46: Obstetrical Doppler
Accurate assessment of gestational age, fetal growth, and the detection of fetal and placental abnormalities are major benefits of sonography. Color Doppler can be used to assist in the identification of vascular architecture, detection of vascular pathology and visualization of blood flow changes associated with physiologic processes and disease states. The clinical applications of obstetrical...
