Heterotopic Pregnancy
A rare condition where simultaneous intrauterine and ectopic pregnancies occur, with increased incidence in ART cycles.
Full Definition
Heterotopic pregnancy represents the coexistence of both intrauterine and extrauterine gestations simultaneously. While extremely rare in natural conception (1:30,000), the incidence increases significantly with assisted reproductive technologies, particularly with multiple embryo transfers. The condition poses diagnostic challenges as the presence of an intrauterine pregnancy can mask symptoms and signs of the concurrent ectopic pregnancy. Beta-hCG levels may appear normal due to the viable intrauterine gestation. Transvaginal ultrasound is essential for diagnosis, though the ectopic component may not be immediately apparent. Treatment requires careful surgical management to preserve the intrauterine pregnancy while addressing the ectopic component.
Usage
Usage note: Always hyphenate as adjective; maintain as two words when used as noun unless specifically modifying another term.
