Ruptured Heterotopic Pregnancy: A Rare Encounter in Acute Surgical Care Settings

摘要

Heterotopic pregnancy is a rare, life-threatening clinical entity with an overall incidence of about 1:30,000 in spontaneous natural conception cases, especially in cases of delayed diagnosis or conflicting clinical features. Here, we present an unusual case of heterotopic pregnancy in a 22-year-old multigravida presented to the emergency department (ED) with a clinical picture of the acute abdomen following recent abdominal trauma. Abdominal ultrasound revealed hemoperitoneum and a single viable intrauterine pregnancy at seven weeks' gestation. Following surgical exploration, the patient underwent removal of the ectopic pregnancy tissue with right salpingectomy. Since the presence of a conflicting history or equivocal physical signs and symptoms makes it difficult to diagnose heterotopic pregnancy, ED physicians and surgeons must consider the diagnosis even when dealing with viable intrauterine pregnancies. Besides, acute abdominal pain associated with shock should be regarded as suggestive of heterotopic pregnancy. Thus, prompt evaluation and a high index of suspicion are of paramount importance to prevent unwanted sequelae.
