Deep arteriovenous placental anastomoses in monochorionic placentas have been considered an essential etiological factor in twin-twin transfusion syndrome (TTTS). Moreover, some investigators have suggested that superficial anastomoses have a protective role. We report on confirmed cases of TTTS with only superficial anastomoses.
单绒毛膜胎盘的深部动静脉吻合被认为是双胎输血综合征（TTTS）的一个重要病因。此外，一些研究者认为表浅吻合具有保护作用。我们报告了仅存在表浅吻合的确诊TTTS病例。
