A case report of spontaneous bilateral perineal hematoma during pregnancy and literature review.
Review in BMC pregnancy and childbirth, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveWe report a rare case of spontaneous bilateral perineal hematoma during pregnancy. We analyze its etiology, clinical features, treatment, and prognosis to provide a reference for clinical practice.
methodsDetailed clinical information was collected, including the patient's pregnancy course, delivery process, imaging findings, and subsequent pregnancy outcomes. We discuss the potential mechanisms, management principles, and prognosis of spontaneous perineal hematoma during pregnancy in light of relevant literature.
resultsThe patient began self-administered perineal massage at 36 weeks of gestation. At 39^+5 weeks, before delivery, bilateral spontaneous perineal hematomas developed. A left mediolateral episiotomy was performed during delivery. After conservative postpartum treatment, the hematomas gradually resolved, and the wound healed well. Eighteen months later, the patient had another vaginal delivery without reoccurrence of perineal hematoma or laceration.
conclusionsSpontaneous perineal hematoma during pregnancy is rare. Its occurrence may be related to increased vascular fragility, venous congestion, and external forces. Although perineal massage in pregnancy may affect perineal tissues, there is no definitive evidence of a direct causal relationship with spontaneous hematoma. Proper guidance on correct technique and force is advised.
