Fetofetal transfusion is due to the twin to twin blood shunt caused by vascular anastomoses. It has been suggested that two types of FFT exist: a chronic form existing during pregnancy, and an acute form occurring only during parturition. Cross-circulation may be demonstrated in monochorionic as well as dichorionic placentas. However, such communications were found in 85-100% of monochorionic placentas, compared with one of 68 dichorionic fused placentas. Authors describe one case of acute feto-fetal transfusion in dichorionic twins.
胎儿-胎儿输血是由血管吻合导致的双胎间血液分流引起的。有人提出存在两种类型的胎儿-胎儿输血:一种是孕期存在的慢性形式,另一种是仅在分娩时出现的急性形式。单绒毛膜胎盘以及双绒毛膜胎盘均可显示交叉循环。然而,85% - 100%的单绒毛膜胎盘存在这种血管交通,而68例双绒毛膜融合胎盘中仅有1例发现此类情况。作者描述了1例双绒毛膜双胎急性胎儿-胎儿输血的病例。
