Internal iliac artery balloon occlusion for placenta accreta spectrum disorder: outcomes and factors influencing efficacy.
Article in BMC pregnancy and childbirth, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundPlacenta accreta spectrum disorder (PASD) is a major obstetric complication associated with life-threatening haemorrhage. Prophylactic internal iliac artery balloon occlusion (IIABO) is used in many centres to reduce intraoperative blood loss but success rates are variable.
methodsWe reviewed 20 consecutive patients with PASD over a twenty-one-month period stratified by procedure type [total abdominal hysterectomy (TAH) versus conservative myometrial repair (MR)] and balloon occlusion use. Estimated blood loss (EBL) was recorded. Welch's t-tests compared groups, and a two-way analysis of variance (ANOVA) assessed the effects of balloon use and procedure type. Effect sizes were expressed as Cohen's d and η².
resultsMean EBL was significantly lower with balloon use than without (1600 ± 666 mL vs. 3222 ± 1871 mL, p = 0.034, Cohen's d = - 1.15). Two-way ANOVA confirmed a main effect of balloon use (η² = 0.28), while procedure type showed no independent effect (p = 0.504). However, EBL values were widely dispersed- with balloons: median 1500 mL (interquartile range {IQR} 1200-1850), range 800-3000; without balloons: median 3000 mL (IQR 1600-5000), range 900-6000 which highlighted the variable efficacy at an individual level.
conclusionProphylactic balloon occlusion reduces blood loss overall in both TAH and MR for PASD, but its efficacy is highly variable. Collateral circulation and scar defect morphology likely underpin this variability, and further research should focus on refining preoperative risk stratification to guide individualised surgical planning with the aid of available imaging techniques.
