Final answer:
Monochorionic twin pregnancies can have outcomes such as single fetal demise, increased mortality risk for surviving twins, and a higher risk of neurological morbidity.
Step-by-step explanation:
Monochorionic twin pregnancies refer to pregnancies where the twins share a placenta and chorionic cavity. The outcomes in monochorionic twin pregnancies can include single fetal demise, an increased mortality risk for the surviving twins, and a higher risk of neurological morbidity. These outcomes are influenced by chorionicity, as twins that share a placenta are more likely to experience complications. The mortality rate and neurological morbidity rate are important factors to consider in these pregnancies.
