Abstract
Amniotic band sequence (ABS) describes highly variable spectrum of congenital anomalies that occur in association with amniotic bands. İntrauterine synechiae is a condition in which scar tissue develops within the uterine cavity. We aim to present a case of ABS and a case of intrauterine synechiae and compare their ultrasonographic findings. Ultrasonography revealed contraction ring in the right groin area of the first fetus but second fetus was healthy. The diagnosis of ABS is based upon the presence of characteristic structural findings on prenatal ultrasound or postnatal physical examination. The diagnosis of intrauterine adhesions is based upon visualization of intrauterine adhesions either directly by hysteroscopy or indirectly by other imaging studies. The floor of the intrauterine adhesions is widely and lateral of the uterine cavity and occurs from four layers while the amniotic band is a thin layer and forms fluctuations in the amniotic fluid. Amniotic bands may cause variable spectrum of congenital anomalies whereas intrauterine adhesions do not increase the probability of fetal anomaly because it is out of the amniotic cavity.

Summary
Amniotic band sequence describes highly variable spectrum of congenital anomalies that occur in association with amniotic bands (1). The estimated incidence of ABS ranges from 1:1200 to 1:15000 in live births (2). It is called a sequence because the pattern of congenital anomalies results from a single defect that can be produced by a variety of different etiologies. The pathogenesis of both amniotic bands and ABS are not firmly established. Etiology and pathogenesis are Address of Correspondence: Submitted for Publication: 17.
