and Kruskal-Wallis tests. P<0.05 was considered statistically significant. Results: Complications in the monochorionic twin population included PTB <34 weeks (14.6%), hypertensive disorders of pregnancy (20.7%), Caesarean section (56.1%), IUFD (2.4%) and abruption (0.6%). For PTB <34 weeks, the prevalence of low CPR was significantly increased at 26.7% versus normal CPR at 6.06% (p=0.002), as was elevated UA-PI at 31.3% versus normal UA-PI at 11.2% (p=0.04), and low MCA-PI at 54.2% versus normal MCA-PI at 6.5% (p<0.001). Hypertensive disorders of pregnancy were associated with a significantly higher prevalence of elevated UA-PI versus normal UA-PI(p=0.03). Caesarean section was associated with a higher frequency of low MCA-PI, compared to vaginal delivery(p=0.006). No statistically significant differences were observed for the relationship between Doppler thresholds and IUFD, as well as abruption. Conclusions: Low CPR, elevated UA-PI and low MCA-PI are significantly associated with PTB <34 weeks in monochorionic twin pregnancies. Further study is needed to better establish the relationships between Doppler variables and adverse obstetrical and neonatal outcomes in monochorionic twins.
