RESUMO
OBJECTIVES: To report a case of tubal heterotopic pregnancy (HP) treated conservatively with transvaginal ultrasound-guided aspiration and instillation of hyperosmolar glucose. METHODS: Aspiration of the tubal ectopic pregnancy and hyperosmolar glucose instillation was performed with a 16-gauge needle under transvaginal ultrasound guidance. RESULTS: Unruptured tubal HP with positive cardiac activity was treated successfully without any further interventions, and intrauterine pregnancy has reached full-term without any complications. CONCLUSIONS: Early diagnosis of this life-threatening condition is the key to its successful treatment. Transvaginal ultrasound-guided aspiration and hyperosmolar glucose injection can be safely performed for the treatment of unruptured tubal HP.
