The tibial transverse transport (TTT) technique has been used to treat this disease in recent years. TTT\u2019s effect remains unclear owing to the lack of large samples and high-quality evidence. Therefore, this study aims to assess TTT\u2019s effectiveness and safety in chronic lower extremity angiopathy treatment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and analysis<\/jats:title>\n                    <jats:p>Relevant studies were acquired by searching the following databases: Cochrane Library, Embase, PubMed, Web of Science, China National Knowledge Infrastructure (CNKI), China Science Technology Journal Database (VIP), Wanfang Data and Chinese Biomedical Literature Service System (CBM) until 20 September 2021. All randomised controlled trials and cohort studies on TTT for chronic lower extremity angiopathy will be included in this review. The primary outcomes will include the healing time and healing rate. The additional outcomes will include the Ankle Brachial Index, amputation rate, ankle skin temperature, Visual Analogue Scale, hospitalisation time, vascular endothelial growth factor, effective rate and complications. We will use Stata V.16.0 software and Review Manager V.5.3 software for meta-analysis. Subgroup and sensitivity analyses will be conducted, if necessary.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Ethics and dissemination<\/jats:title>\n                    <jats:p>This study was based on previous data.
