Current knowledge about human development is based on the description of a limited number of embryonic specimens published in original articles and textbooks, often more than 100 years ago. It is exceedingly difficult to verify this knowledge, given the restricted availability of human embryos. We created a three-dimensional digital atlas and database(More)
BACKGROUND Doppler flow velocities of the ductus venosus are increasingly used to assess fetal increased nuchal translucency, growth-restriction and monochorionic twins, and might contribute to screening for cardiac defects. It is disputed whether a sphincter at the ductus venosus inlet actively regulates blood flow. AIMS This study aims to define the(More)
Duodenal polypoid masses are an uncommon finding mainly diagnosed incidentally at endoscopy or surgery. We report a 39-year-old female patient with symptoms of intermittent stabbing pain in the upper right abdominal quadrant and an iron deficiency anaemia, without complaints of weight loss, haematemesis or melaena. A duodenal polyp and acute duodenitis have(More)
Knowledge of complex morphogenetic processes that occur during embryonic development is essential for understanding anatomy and to get insight in the pathogenesis of congenital malformations. Understanding these processes can be facilitated by using a three-dimensional (3D) developmental series of human embryos, which we aim to create in this project.(More)
OBJECTIVES/HYPOTHESIS The hyoid-larynx complex is highly prone to anatomical variation. The etiology of anatomical variants such as Eagle's syndrome and the aberrant hyoid apparatus can be explained from embryonic development. Modern textbooks state that the hyoid bone body develops from the second and third pharyngeal arch cartilages, and that thyroid(More)
OBJECTIVES To provide comprehensive illustrations of anatomy of the relevant vessels in large experimental animals in an interactive format as preparation for developing an effective and safe transcatheter technique of aortopulmonary and bidirectional cavopulmonary intervascular anastomoses. METHODS Computed tomographic angiographic studies in two calves(More)
Since the multi-site closure theory was first proposed in 1991 as explanation for the preferential localizations of neural tube defects, the closure of the neural tube has been debated. Although the multi-site closure theory is much cited in clinical literature, single-site closure is most apparent in literature concerning embryology. Inspired by Victor(More)
