OBJECTIVE: To develop a simple and systematic algorithm to determine chorionicity and amnionicity in the second and third trimester by ultrasound.
STUDY DESIGN: The algorithm was constructed based upon years of experience in examining multifetal pregnancies and by adopting the different sonographic signs suggested in the literature.
RESULTS: The following parameters were used to construct the algorithm: sexing of the fetuses, placental location, and origin, thickness and number of layers of the membranes.
CONCLUSION: The flow chart developed is simple to use and embodies all possible sonographic parameters to help determine chorionicity and amnionicity in the second and third trimester.
