To date, velamentous insertion of umbilical cord has not been a topic of interest. It has regarded as a phenomenon without clinical significance rather than a disease. Furthermore, antenatal diagnosis of velamentous insertion has been thought as an impossible task. Recently, some investigators raised the clinical importance of velamentous insertion of umbilical cord, especially in multiple gestation. Below we report on a case of velamentous insertion of umbilical cord in discordant twins conceived by in vitro fertilization. The aim of this report is to emphasis the clinical significance of velamentous insertion of umbilical cord in twin gestation. The velamentous insertion of umbilical cord can cause twin-twin transfusion syndrome (TTTS) and pseudo TTTS. Besides, the possible correlation between the high incidence of velamentous insertion of umbilical cord and discordancy in twin pregnancy obtained by in vitro fertilization is also discussed in this report in conjunction with the case.
