Animal Models of Lymphaticovenous Anastomosis: A Systematic Review of Current Evidence and Future Directions in Translational Research.
Synthesis in Microsurgery, 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
backgroundLymphovenous bypass (LVB) or lymphaticovenous anastomosis (LVA) is increasingly applied, including experimental use for Alzheimer's disease via cervical lymphatic pathways. However, literature on long-term patency and failure mechanisms is scarce, and no gold standard exists for evaluating durability. Robust, reproducible LVA models are essential to advance translational research. This review maps current animal models and proposes strategies for improving reliability and mechanistic insight.
methodsA PRISMA-guided search of PubMed, Scopus, and Google Scholar identified original animal studies reporting intra- or postoperative patency using functional or structural methods. Extracted data included species, anastomosis type, assessment tools, follow-up intervals, patency rates, and histology.
resultsOf 107 records screened, 11 met criteria: rats (n = 7), rabbits (n = 1), piglets (n = 1), and canines (n = 2). Techniques were mainly end-to-end (n = 9) and end-to-side (n = 2), targeting femoral, iliolumbar, popliteal, mesenteric, cervical, and thoracic-duct outflows. Intraoperative patency was uniformly high (≥ 90%). Postoperative patency was reported in six studies, ranging from 80% to 100% at ≤ 7 days (ICG lymphography) to 67% at 1 month (canines). Histology (three studies) distinguished patent sites (smooth endothelium) from failed ones (irregular endothelium, thrombus, fibrosis). Follow-up was categorized as short-term (0-7 days), mid-term (2-4 weeks), and long-term (≥ 1 month), but standardized long-term outcomes were absent.
conclusionsFuture models should integrate noninvasive imaging, serial long-term follow-up, and detailed histologic and molecular analysis to clarify success and failure mechanisms. Standardized methodologies will enhance translational relevance, refine surgical techniques, and inform therapies to improve LVA durability.
