Uterine sheets

A uterine sheet is a shelf-like structure that runs fromnorth to south within the uterine cavity and probably represents in most cases a uterine adhesion.
Thisfinding is observed in 0.4–0.6% of pregnancies. Althoughsome authors have noted a somewhat higher cesarean section rate in those with uterine sheets, these studies havenot demonstrated an adverse effect on the fetus, and cer-
tainly should be distinguished from a true amniotic band,which has a different clinical connotation. Only one recent series of uterine sheets from Asia contained twointrauterine fetal demises, presumably due to a cord accident. The authors described two variants of uterine sheets:complete, where there are no loose ends, and incomplete,
where the shelf appears to be waving in the breeze. Fetal demise occurred in the two cases of “complete” sheetswhile the remaining 36 “incomplete” sheets were not associated with adverse outcome. They postulated that acomplete sheet was not necessarily innocuous.In
contrast, my experience is that most of our sheets fallinto the complete variety, and none has ever been associated with intrauterinedemise or any other adverse outcome. The only complication we have encountered has been the anxiety created by patients being told that theyhave an amniotic “band.” After a quick search on the Internet, these patients are so wired by the time they arriveat our office, their feet are barely touching the ground.Amn- iotic band syndrome is a rare condition that, unfortunately, is associated with severe fetal abnormalities andis, much of the time, lethal. usually associated with potter’s syndrome
