Acardiac Parabiotic Triplet.

Acardiac parabiotic twin commonly known as parasite occurs rarely and may lead to high output cardiac failure, hydrops or premature delivery in the pump fetus. Doppler USG of acardiac fetal umbilical vessels and fetal echocardiography aids in the diagnosis. Treatment can be done prenatally by stopping the blood flow to the acardiac twin without affecting the pump twin, achieved by endoscopic (fetoscopic) ligation or laser coagulation of the umbilical cord or Bipolar cauterization or intra-fetal radio frequency ablation or USG guided thrombosis of umbilical cord.
