Abnormalities of the placenta
Normal placental structure and function is essential for a healthy pregnancy; the placenta is responsible for nutrient and oxygen transport, removal of waste products, protection from infection, modulation of the maternal immune system and hormone production to maintain pregnancy. The human placenta is structurally adapted to fulfil this role as it is haemomonochorial, minimising the distance b...
متن کاملStructural abnormalities in the placenta
Genes regulate the development of fertilised egg into the inner cell mass (which will become the embryo, fetus and, eventually, baby) and the trophoblast (which will become the placenta). Defects in the genes that regulate these processes lead to a wide range of embryonic, fetal and neonatal defects, from minor cosmetic abnormalities, to such severe defects disasters that a pregnancy miscarries...
متن کاملPlacenta pathology associated with maturation abnormalities
The placenta is the fastest growing organ of the human body. The placenta grows from a single cell to approximately 5x10 cells in 38 weeks. A good blood supply from maternal blood via the spiral arteries to the placenta is not only very important for the foetus but also very important for normal development of the placenta. The maternal blood is supplied to the placenta by spiral arteries. Appr...
متن کاملConduction abnormalities after transcatheter aortic valve implantation
In the last few years, transcatheter aortic valve implantation (TAVI) has become an alternative procedure in patients with severe aortic stenosis and high risk for surgical aortic replacement. Due to the anatomic correlation between aortic valve structure and conduction system of the heart, one of the most common complications after TAVI is conduction system disturbances which including bundle ...
متن کاملCochlear implantation in congenital cochlear abnormalities.
Many children have benefited from cochlear implant device including those with congenital malformation of the inner ear. The results reported in children with malformed cochlea are very encouraging. We describe 2 cases of Mondini's malformation with severe sensorineural hearing loss. Cochlear implantation was performed and both of them underwent post-implantation speech rehabilitation. Post-imp...
