Caesarean Scar Ectopic Pregnancy Complicated by Uterine Rupture at 10 Weeks Gestation

First-trimester uterine rupture: a case report and systematic review of the literature

OBJECTIVE

This study aimed to present a case of first-trimester uterine rupture and perform a systematic review to identify common presentations, risk factors, and management strategies.

DATA SOURCES

Searches were performed in PubMed, Ovid, and Scopus using a combination of key words related to "uterine rupture," "first trimester," and "early pregnancy" from database inception to September 30, 2020.

STUDY ELIGIBILITY CRITERIA

English language descriptions of uterine rupture at ≤14 weeks of gestation were included, and cases involving pregnancy termination and ectopic pregnancy were excluded.

METHODS

Outcomes for the systematic review included maternal demographics, description of uterine rupture, and specifics of uterine rupture diagnosis and management. Data were extracted to custom-made reporting forms. Median values were calculated for continuous variables, and percentages were calculated for categorical variables. The risk of bias was assessed using the Joanna Briggs Institute critical appraisal checklist for case reports and case series.

RESULTS

Overall, 61 cases of first-trimester uterine rupture were identified, including our novel case. First-trimester uterine ruptures occurred at a median gestation of 11 weeks. Most patients (59/61 [97%]) had abdominal pain as a presenting symptom, and previous uterine surgery was prevalent (44/61 [62%]), usually low transverse cesarean delivery (32/61 [52%]). The diagnosis of uterine rupture was generally made after surgical exploration (37/61 [61%]), with rupture noted in the fundus in 26 of 61 cases (43%) and in the lower segment in 27 of 61 cases (44%). Primary repair of the defect was possible in 40 of 61 cases (66%), whereas hysterectomy was performed in 18 of 61 cases (30%). Continuing pregnancy was possible in 4 of 61 cases (7%).

CONCLUSION

Uterine rupture is an uncommon occurrence but should be considered in patients with an acute abdomen in early pregnancy, especially in women with previous uterine surgery. Surgical exploration is typically needed to confirm the diagnosis and for management. Hysterectomy is not always necessary; primary uterine repair is sufficient in more than two-thirds of the cases to achieve hemostasis. Continuing pregnancy, although uncommon, is also possible.

First Trimester Uterine Rupture: A Case Report and Literature Review

The aim is to report a case of spontaneous uterine rupture in the first trimester of pregnancy and to review the literature on the topic.

METHODS

A literature search was performed using PubMed and Scopus. Relevant English articles were identified without any time or study limitations. The data were aggregated, and a summary statistic was calculated.

RESULTS

A 35-year-old gravida 5, para 2 was admitted at our department because of fainting and abdominal pain. The woman had a first-trimester twin pregnancy and a history of two previous cesarean sections (CSs). Suspecting a uterine rupture, an emergency laparotomy was performed. The two sacs were completely removed, and the uterine rupture site was closed with a double-layer suture. The patient was discharged from hospital four days later in good condition. On the basis of this experience, a total of 76 case reports were extracted from PubMed and included in the review. Fifty-three patients out of 76 (69.74%) underwent previous surgery on the uterus. Most women (67.92%) had a CS, and in this group a cesarean scar pregnancy (CSP) or a placenta accreta spectrum (PAS) disorder was found to be the etiology in 77.78% of cases. Furthermore, 35.85% of the women had hysterectomy after uterine rupture. Twenty-three patients out of 76 (30.26%) had an unscarred uterus. Of this group, most women presented a uterine anomaly (43.48%). Moreover, 17.39% of these women had a hysterectomy.

CONCLUSION

According to the literature, the current pandemic use of CS explains most cases of first-trimester uterine rupture.
