JIMENEZ PUNALES, Sandi; FLEITES LEON, Aracelys  and  VEGA BETANCOURT, Nuria. Ruptured vasa previa in a velamentous umbilical cord insertion. Medicentro Electrónica [online]. 2020, vol.24, n.1, pp. 198-206. ISSN 1029-3043.

Ruptured vasa previa is an uncommon condition that appears when the umbilical cord has a velamentous insertion and the unprotected fetal vessels, which, in the absence of Wharton's jelly, run through membranes making them especially vulnerable to rupture or tears. The most relevant risk factors are: monochorionic twin pregnancy, pregnancies achieved through assisted reproductive techniques and abnormal placental cord insertion. Ruptured vasa previa can lead to: acute fetal hemorrhage, hypovolemic shock, fetal asphyxia and perinatal death. The ultrasound study of the placenta and the use of color Doppler ultrasound are of great importance to achieve early diagnosis of patients at risk, which is the fundamental premise to achieve lower fetal and neonatal morbidity and mortality.

Keywords : vasa previa; umbilical cord.
