Analysis of middle cerebral artery peak systolic velocity in monochorionic twin pregnancies as a method for identifying spontaneous twin anaemia-polycythaemia sequence.

A regular Doppler control evaluation of middle cerebral artery peak systolic velocity is needed in order to identify twin anaemia polycythaemia sequence in monochorionic twin pregnancies. Here, we present a clinical case of spontaneous TAPS, and we review the diagnostic criteria and management strategies for this syndrome.
