Stuck twin syndrome usually presents with polyhydramnios in the recipient sac and severe oligohydramnios in the donor sac. The donor is displaced against the uterine wall and remains adherent in that position. We present a case in which the diagnosis was more complicated, owing to the suspension of the stuck twin by a sling within the sac of the recipient. A monochorionic diamnionic twin gestation was complicated by twin-twin transfusion syndrome at 18 weeks of gestation. In our example, the stuck twin was suspended by a sling from the placenta. The sling band represented the intertwin membrane that was folded upon itself. Amniotic fluid from the recipient twin was present in three dimensions around the stuck twin, except for the sling band. The suspension of the stuck twin by a sling within the amniotic fluid of the recipient is an unusual manifestation of the stuck twin syndrome.
联体双胎综合征通常表现为受血儿羊膜囊羊水过多，供血儿羊膜囊羊水过少。供血儿被挤压贴于子宫壁并持续粘连于该位置。我们报告一例诊断更为复杂的病例，因为联体双胎被受血儿羊膜囊内的一条索带悬吊着。单绒毛膜双羊膜囊双胎妊娠在妊娠18周时并发双胎输血综合征。在我们的病例中，联体双胎被一条来自胎盘的索带悬吊着。索带代表自身折叠的双胎间胎膜。除索带外，受血儿的羊水在联体双胎周围呈三维分布。联体双胎被受血儿羊膜囊内的索带悬吊是联体双胎综合征的一种不寻常表现。
