title: Advanced abdominal pregnancy: an increasingly challenging clinical concern for obstetricians.
abstract: Advanced abdominal pregnancy is rare. The low incidence, high misdiagnosis rate, and lack of specific clinical signs and symptoms explain the fact that there are no standard diagnostic and treatment options available for advanced abdominal pregnancy. We managed a case of abdominal pregnancy in a woman who was pregnant for the first time. This case was further complicated by a concurrent singleton intrauterine pregnancy; the twin pregnancy was not detected until 20 weeks of pregnancy. The case was confirmed at 26 weeks gestational age using MRI to be an abdominal combined with intrauterine pregnancy. The pregnancy was terminated by cesarean section at 33 + 5 weeks gestation. We collected the relevant data of the case while reviewing the advanced abdominal pregnancy-related English literature in the Pubmed, Proquest, and OVID databases. We compared and analyzed the pregnancy history, gestational age when the diagnosis was confirmed, the placental colonization position, the course of treatment and surgical processes, related concurrency rate, post-operative drug treatment programs, and follow-up results with the expectation to provide guidance for other physicians who might encounter similar cases.
