Computed Tomographic Angiography (CTA)-guided precision reconstruction in complex lower leg wounds.
Article in BMC surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundReconstruction of complex lower leg wounds presents significant challenges due to extensive soft tissue damage, vascular variations, and potential neurovascular injuries. While flap transfer, particularly free flaps, remains the preferred method for reconstruction, the lack of precise preoperative vascular information often complicates surgical planning. This study introduces a Computed Tomographic Angiography (CTA)-guided approach for precision reconstruction to address these challenges. PURPOSE: This study aims to elucidate the critical role of precise preoperative assessment of recipient-site vasculature using Computed Tomographic Angiography (CTA) in optimizing surgical outcomes for complex lower leg wound reconstruction.
methodsFrom March 2013 to October 2023, 57 patients with complex lower leg defects underwent reconstruction using CTA-guided flap surgery. Patient demographics, injury characteristics, and surgical outcomes were retrospectively analyzed. Preoperative CTA was employed to map donor and recipient vascular anatomy, evaluate perforator vessels, and guide flap selection and design. Flap options included anterolateral thigh perforator (ALTP) and deep inferior epigastric perforator (DIEP) flaps, with selection tailored to wound dimensions, depth, and vascular conditions.
resultsFlap sizes ranged from 5 × 10 cm to 55 × 70 cm, 54 flaps survived completely (94.7%), 1 partial necrosis requiring revision (1.8%), and 2 total flap losses (3.5%). CTA demonstrated 100% concordance with intraoperative vascular findings, enabling precise recipient vessel localization and enhanced surgical efficiency. Postoperative complications included vascular compromise (8.8%), flap bulkiness (19.3%), and minimal wound dehiscence (1.8%). Functional and aesthetic outcomes were rated as excellent in 61.4% of cases.
conclusionThe CTA-guided reconstruction approach enables comprehensive preoperative vascular assessment, optimizing donor flap selection and recipient vessel anastomosis. This evidence-based method significantly improves surgical precision and outcomes, representing an advancement over traditional empirical techniques in managing complex lower leg wounds.
