RESUMO
El útero unicorne con cuerno rudimentario es una anomalía mulleriana rara con una alta incidencia de complicaciones obstétricas que afecta al 4,5% de las mujeres. La gestación albergada en él ocurre en uno de cada 76.000 embarazos con un riesgo de rotura uterina de un 50-80% y ocurre normalmente a final del segundo trimestre del embarazo. El diagnóstico precoz reduce la morbimortalidad, pero la sensibilidad diagnóstica por ecografía es solo del 30%, dada la baja prevalencia de la enfermedad. Presentamos el caso de una gestante de 22 semanas, con cesárea previa, con abdomen agudo y shock hipovolémico por rotura de un cuerno rudimentario uterino (AU)
Unicornuate uterus with rudimentary horn is a rare Müllerian anomaly with a high incidence of obstetric complications, affecting 4.5% of women. Pregnancy located in the rudimentary horn occurs in 1 in 76,000 pregnancies with a risk of uterine rupture of 50-80%. Rupture usually occurs at the end of the second trimester of pregnancy. Early diagnosis reduces morbidity and mortality, but ultrasound diagnosis has a sensitivity of only 30%, due to the low prevalence of this entity. We report the case of a woman at 22 weeks of pregnancy with a previous cesarean delivery, who presented with acute abdomen and hypovolemic shock due to a ruptured rudimentary horn (AU)
