Prophylactic internal Iliac artery balloon occlusion in placenta accreta spectrum: evaluating efficacy, risks, and clinical implications.

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
introductionThis study aimed to assess the efficacy and risks of prophylactic internal iliac artery balloon occlusion (IIABO) in managing placenta accreta spectrum (PAS) disorders and to discuss the clinical implications of this technique.
methodsWe retrospectively analyzed 616 confirmed patients with PAS, including placenta accreta, increta, and percreta, between December 2013 and December 2022. Patients were divided into two groups based on whether or not they received prophylactic IIABO (balloon group, n = 310; no balloon group, n = 306). The primary outcomes were intraoperative bleeding volume and operation duration. Secondary outcomes included transfusion volumes, arterial injury rates, thrombosis, lower extremity ischemia, and hospitalization costs. The diagnosis of PAS was based on ultrasonography and verified by MRI when needed. Clinical management, surgical outcomes, complications, and hospitalization-related outcomes were compared between the groups using independent sample t tests, Mann‒Whitney U tests, or Fisher's exact tests, as appropriate.
resultsThe balloon group had less intraoperative bleeding and lower transfusion volumes, with a significant difference only between placenta percreta patients (P = 0.03), who also demonstrated a shorter operation duration (P = 0.02). No significant differences were observed in demographics, placenta removal, hysterectomy, or obstetric complications between the groups. The balloon group had greater rates of arterial injury, thrombosis, and lower extremity ischemia (without significant differences) and experienced greater hospitalization costs (P = 0.01). The balloon blocking time significantly increased from the placenta accreta to placenta increta subgroups and then to the placenta percreta subgroup (P = 0.03).
conclusionsProphylactic IIABO can be beneficial for reducing intraoperative bleeding and operation duration in selected PAS patients, particularly those with placenta percreta. However, the increased vascular complications and costs must be weighed carefully. Further studies should focus on optimizing patient selection and minimizing complications.
