Cornual ectopic pregnancy is a rare condition affecting 2-4% of ectopic pregnancies. This retrospective study highlights its significant maternal mortality risk due to rupture, emphasizing the need for timely diagnosis and management.

Area of Science:

  • Obstetrics and Gynecology
  • Reproductive Medicine
  • Surgical Pathology

Background:

  • Cornual ectopic pregnancy is a rare but life-threatening condition, accounting for 2-4% of all ectopic pregnancies.
  • It is associated with a high maternal mortality rate due to potential rupture at advanced gestational ages, leading to severe hemodynamic instability.

Purpose of the Study:

  • To investigate the incidence, clinical presentation, and management outcomes of cornual ectopic pregnancy.
  • To analyze the complications and maternal mortality associated with this rare obstetric emergency.

Main Methods:

  • A retrospective study was conducted from January 1989 to December 1994 at the Instituto Nacional de Perinatologia.
  • Data were collected on maternal age, gestational age at diagnosis, clinical signs and symptoms, surgical treatment, complications, and histopathology for 6 cases of cornual ectopic pregnancy.

Main Results:

  • The incidence of cornual ectopic pregnancy was found to be 1 in 5846 deliveries (0.01% of all deliveries, 4.02% of ectopic pregnancies), aligning with global literature.
  • Average maternal age was 31.5 years, with diagnosis occurring between 7.1 and 24 weeks of gestation.
  • All patients presented with abdominal pain and amenorrhea; 2 had vaginal bleeding. Total abdominal hysterectomy was required in 100% of cases, with shock being the primary complication, though no maternal deaths occurred.

Conclusions:

  • Cornual ectopic pregnancy, though rare, poses a significant risk of severe complications, including shock.
  • Prompt diagnosis and surgical intervention, often requiring hysterectomy, are crucial for managing this condition and preventing maternal mortality.
