First Case of Sirenomelia Type III in Ukraine

Abstract

Sirenomelia in monochorionic diamniotic twins is extremely rare pathology. According to the literature data, there are only 24 cases, in which one or both fetuses had sirenomelia. The incidence rate of sirenomelia ranged from 1.1 to 4.2/60,000–100,000 deliveries and associated with the high lethality during early perinatal period. Here, we present a monochorionic diamniotic twin pregnancy, where one fetus was diagnosed with sirenomelia associated with agenesia of one kidney and bladder, and the co-twin was absolutely healthy.
