Laser Fluorescence Imaging of Vascular Territories in Lipoabdominoplasty.
Article in Plastic and reconstructive surgery. Global open, 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
Background: Although limited dissection is commonly thought to enhance flap perfusion during abdominoplasty, recent evidence indicates otherwise. This study used intraoperative fluorescence imaging to elucidate the dynamic role of vascular territories in ensuring flap viability. Methods: Twenty consecutive women undergoing liposuction and abdominoplasty were prospectively studied, with a 100% inclusion rate. Flap perfusion was assessed immediately postoperatively using the SPY Elite System. Vascular zones were classified based on capture timing and intensity. Results: The subcostal zone was the primary vascular contributor, perfused first and with the highest intensity. Intercostal vessels played a secondary role, whereas thoracoabdominal vessels were primary contributors in only 1 case. No complications were observed. Conclusions: This study highlights the critical role of the subcostal and intercostal vessels in flap perfusion after wide undermining and underscores the need to preserve these territories during abdominoplasty.
