Rudimentary Horn Pregnancy Cases: Systematic Review of 21st Century Outcomes

A systematic review of English-language case reports and series published from 2000 onward identified 187 cases of non-communicating rudimentary horn pregnancy across 163 publications. The dataset compiles patient characteristics, diagnostic modalities, management strategies, and maternal-fetal outcomes, including a reported rupture rate of 44% and a maternal mortality rate of 1.2%. It supports analysis of trends in minimally invasive surgical management for this rare, high-risk ectopic gestation.

Use Cases

• Analyzing risk factors and outcomes for placenta accreta spectrum, reported in 39% of cases.
• Comparing diagnostic modalities and the frequency of intraoperative diagnosis.
• Evaluating the adoption and outcomes of minimally invasive surgical techniques, including robotic-assisted resection.
• Assessing maternal mortality and morbidity rates associated with second-trimester rupture.

Strengths

• Compiles a substantial number of cases (187) from a defined time period (2000 onward).
• Data extraction followed a systematic methodology (PRISMA 2020 guidelines).
• Cross-platform presence on figshare indicates established sharing and potential for reuse.

Limitations

• Evidence is based on retrospective case reports, which are prone to publication bias and heterogeneity.
• Specific column names and the exact row count for the underlying data table are not provided in the metadata.
• The dataset's primary file is a DOCX document, which may require extraction to access structured data.
