Does Intraoperative Heparin Administration Reduce Postoperative Complications in Deep Inferior Epigastric Perforator Flap Breast Reconstruction?

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
Background: Microsurgical thrombosis is a critical complication of free flap surgery. Evidence evaluating the efficacy of intraoperative thromboprophylaxis in mitigating this complication during deep inferior epigastric perforator (DIEP) flap breast reconstruction remains limited. Here, we report a retrospective analysis of all DIEP flap breast reconstructions performed at our institution during a 6-year period. Methods: This single-center analysis offers a retrospective review of all female patients who underwent DIEP flap breast reconstruction from January 2018 to June 2024. Subjects were divided into 2 groups: a control group and a treatment group that received an intraoperative bolus administration of 2000 IU of unfractionated heparin (UFH). Patient characteristics, therapeutic variables, intraoperative details, and postoperative outcomes were extracted and analyzed. Postoperative complications were classified into subgroups: acute complications (≤4 d) and delayed complications (>4 d). Results: This study included 114 patients (141 breasts), corresponding to 48 patients in the control cohort and 66 patients in the UFH cohort. No significant differences were observed in the occurrence of complications in intraoperative ( Conclusions: Intraoperative anticoagulant prophylaxis using UFH did not diminish acute thrombotic complications; however, it was also not associated with an increased risk of hematoma and bleeding. These findings offer valuable insights regarding the clinical relevance and safety profile of perioperative UFH administration.
