Abstract

Objective: To investigate the risk factors and clinical characteristics of recurrent ectopic pregnancy at a tertiary obstetrics and gynecology hospital in Vietnam. Subjects and Methods: A retrospective descriptive study was conducted on all patients with recurrent tubal ectopic pregnancy who were treated at Hanoi Obstetrics and Gynecology Hospital. Results: The rate of recurrent ectopic pregnancy was 6.87%, of which 85.96% occurred in the contralateral fallopian tube and 14.04% recurred in the same tube. Among the associated factors, the most common age group was 30–35 years, primarily consisting of workers and office employees. The most frequent risk factor was a history of lower genital tract infection (44.38%). Clinical presentations included: delayed menstruation combined with abdominal pain and vaginal bleeding, which had the highest prevalence at 48.87%; painful cul-de-sac sign was the most common at 59.56%; and painful adnexal mass was observed in 38.2%. The β-hCG level between 1000–2000 mIU/ml was the most frequent, accounting for 38.08%. Up to 99.44% of cases had no gestational sac in the uterine cavity, and 64.6% showed no signs of anemia. Conclusion: Risk factors for recurrent ectopic pregnancy include the 30–35 age group, occupation as workers/employees, and a history of lower genital tract infection. The clinical characteristics is generally similar to primary ectopic pregnancy, most commonly delayed menstruation and adnexal pain.
