Late postpartum hemorrhage caused by rupture of a uterine artery aneurysm in a patient with Takayasu arteritis: a case report.
Article in Journal of medical case reports, 2026. 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
backgroundUterine artery aneurysms are extremely rare vascular abnormalities. Their rupture during pregnancy, delivery, or the postpartum period can result in life-threatening hemorrhage, yet clinical understanding of this condition remains limited. CASE PRESENTATION: We report a rare case of right uterine artery aneurysm rupture that led to severe late postpartum hemorrhage. The patient was a 34-year-old Asian woman with a history of Takayasu arteritis, who presented with acute, massive vaginal bleeding 10 days after vaginal delivery. Selective arteriography confirmed that the hemorrhage was caused by the rupture of the right uterine artery aneurysm. The patient was successfully treated with selective uterine artery embolization, avoiding hysterectomy and preserving her reproductive function.
conclusionsThis case underscores the importance of considering uterine artery aneurysm rupture as a rare but critical cause of late postpartum hemorrhage, especially in patients with underlying vasculopathies such as Takayasu arteritis. Timely angiographic diagnosis and interventional embolization are essential for achieving hemostasis and optimizing patient outcomes.
