Effects of Harvesting Site and Incision Method on Surgical Wound Complications of No-Touch Saphenous Vein Grafts: A Retrospective Observational Study.
Observational study in Brazilian journal of cardiovascular surgery, 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
introductionSaphenous vein grafts are frequently used for coronary artery revascularization. However, harvesting veins is associated with infected surgical sites and other complications. The no-touch technique that includes harvesting saphenous vein grafts along with surrounding tissues improves graft patency but increases the frequency of wound complications. We harvested saphenous vein grafts using the no-touch technique and devised other options for sites and incision methods to prevent wound complications. This study aimed to determine the clinical outcomes of no-touch saphenous vein grafts as well as associations between harvesting methods and wound complications.
methodsWe enrolled 132 patients who underwent isolated coronary artery bypass surgery with saphenous vein grafts harvested using the no-touch technique. Wound condition, general status, and graft patency were assessed during clinical follow-up.
resultsWe harvested 180 veins (lower legs, n = 69 veins; upper legs, n = 111) using longitudinal and skip incisions at 100 and 80 sites, respectively. Wound complications occurred at 35 sites. The frequency of complications was significantly lower in the upper, than in the lower legs (14.4% vs. 27.5%). Furthermore, wound complications were reduced more by skip, than by longitudinal skin incisions (16.3% vs. 20.0%).
conclusionWe devised a method to harvest no-touch saphenous vein grafts and determined the clinical outcomes of saphenous vein grafts and harvesting sites. Harvesting from the upper leg and via skip incisions reduced the frequency of wound complications.
