Monochorionic triamniotic multiple pregnancy is a rare and high-risk condition. We present the management of a cascade of severe complications in an adolescent pregnant patient. A 17-year-old primigravida with a 24-week monochorionic triamniotic triplet pregnancy was admitted for threatened preterm labor with cervical dilation. A rescuecervical cerclage was performed. The clinical course was complicated by high-risk pulmonary thromboembolism, confirmed by echocardiography and Doppler ultrasonography, requiring therapeutic anticoagulation. Subsequently, the patient developed nosocomial pneumonia and severe anemia. At 26.3 weeks of gestation, an emergency cesarean sectionwas performed due to labor, delivering three preterm newborns. The mother experienced uterine atony, which was successfully managed with compressive sutures. This case underscores the feasibility of an aggressive, multidisciplinary approach in critical obstetric situations with sequential complications. Individualized decision-making, despite limited evidence in such complex scenarios, can lead to favorable maternal and fetal outcomes. Adolescence may be an additional risk factor in multiple pregnancies.
