Twin-to-twin transfusion syndrome (TTTS), also known as feto-fetal transfusion syndrome (FFTS), twin oligohydramnios-polyhydramnios sequence (TOPS) and stuck twin syndrome, is a complication of monochorionic multiple pregnancies (the most common form of identical twin pregnancy) in which there is disproportionate blood supply between the fetuses.
On the right, the "pump twin" which supplies the acardiac twin with blood. A selective termination of the acardiac twin reduces the risk of death of the pump twin. Selective reduction is used when a mother is carrying an unsafe or undesirable number of fetuses in a multiple pregnancy, which are common in medically assisted pregnancies. The ...
Illustration of TRAPS pregnancy. On the left, the acardiac twin. The pump twin is on the right. Selective termination of the acardiac twin can reduce the risk of death of the pump twin. Twin reversed arterial perfusion sequence, also called TRAP sequence, TRAPS, or acardiac twinning, is a rare complication of monochorionic twin pregnancies. [1]

Occasionally a human birth is anything but ordinary. A recent report highlighted a rare case from 2010, in which a baby girl born in Hong Kong was found to be carrying twin fetuses. The study ...
The twin reversed arterial perfusion, or T.R.A.P. sequence, results in an 'acardiac twin', a parasitic twin that fails to develop a head, arms and a heart.The parasitic twin, little more than a torso with or without legs, receives its blood supply from the host twin by means of an umbilical cord-like structure, much like a fetus in fetu, except the acardiac twin is outside the autosite's body.
It's crazy how high risk mono-mono twins can be, and how good they're doing now, it's really a blessing," says Magnani. Ava and Anna were delivered by C-section on Thursday, weighing just four and ...
Superfetation (also spelled superfoetation – see fetus) is the simultaneous occurrence of more than one stage of developing offspring in the same animal. [1] [2] [3]In mammals, it manifests as the formation of an embryo from a subsequent menstrual cycle, while another embryo or fetus is already present in the uterus.
