Omental flap coverage to treat symptomatic perigraft hygroma recurrence after aortic aneurysm repair.
Article in Journal of vascular surgery cases and innovative techniques, 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
Perigraft hygroma (PGH) is a sterile fluid collection that forms around an aortic graft following aneurysm repair; it occurs in up to 18% of cases. Despite its relatively high incidence, optimal management of PGH is not clearly defined. We present a case of a 65-year-old male with an extensive aortic surgical history who developed a large, symptomatic PGH. The patient underwent open evacuation and pedicled omental flap coverage in an effort to treat symptoms while avoiding the morbidity of graft excision. His symptoms resolved postoperatively. However, imaging at 2 months showed recurrence of the PGH, although reduced in size compared with preoperatively. This case suggests that drainage and omental flap coverage may be useful in treating PGH symptoms but does not prevent recurrence.
