متن کاملSuccessful Surgical Separation of Thoraco-Omphalopagus Symmetrical Conjoined Twins in Iran: Two Case Reports
Conjoined twins are derived from the division of a single fertilized ovum; a phenomenon accompanied with multiple congenital anomalies. Such twins are identical, of the same sex, and more likely to be female. Most twins die during the embryonic period, and only 18% survive longer than 24 hours. There are complex anomalies in thoraco-omphalopagus twins that makes them unlikely to live long enoug...

The aetiology of conjoined twins is unknown with no established risk factors. The pathogenesis is also uncertain but if cell differentiation takes place after the 14th day of embryonic development, incomplete cleavage will result in the formation of conjoined twins. A system of classification established by St Hiliaire in 1832 is still used today and is based on which structures are fused. The ...
متن کاملOmphalopagus conjoined twins: ultrafast MR imaging findings.
Conjoined twins are a rare and often catastrophic obstetrical event. Although ultrasonography is widely used in the diagnosis of conjoined twins, it may fail to demonstrate the details in fetuses with complex anomalies, especially during late pregnancy. We present an omphalopagus conjoined twins case evaluated by HASTE magnetic resonance imaging, which showed the conjunction site and cranial an...
