However, collateral venous networks may offer an alternative solution, allowing for the creation of peripheral AV access. This study evaluates the outcomes of AV access construction in hemodialysis patients with SVCO.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>A retrospective review of 18 patients with SVCO and patent azygous veins was conducted between August 2021 and June 2023. These patients underwent peripheral AV access creation, including fistulas and grafts. Collected data included baseline demographics, preoperative 3D CT reconstruction of thoracic vessels, central venography, vascular access types, surgical details, postoperative complications, and the timing and methods of interventions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>AV access was successfully created in all patients, including 15 AV fistulas and 3 AV grafts. The average brachial blood flow rate before cannulation was 848.67\u2009\u00b1\u2009132.03\u2009mL\/min. The median follow-up period was 18.5\u2009months (range: 10\u201332\u2009months). During follow-up, six patients required interventions, such as flow reduction or percutaneous transluminal angioplasty, to optimize blood flow or resolve venous obstruction. Two cases were classified as failed access at 10 and 18\u2009months post-creation. One patient transitioned to peritoneal dialysis due to AVG dysfunction, while the other underwent bypass surgery for chylothorax.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>AV access can be successfully created and maintained in patients with SVCO and a patent azygous vein. Although mild venous obstruction symptoms may develop during follow-up, timely intervention can preserve access patency. For patients with limited vascular resources and challenging catheterization, this approach represents a viable option for establishing effective access.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/11297298241304477","type":"journal-article","created":{"date-parts":[[2024,12,12]],"date-time":"2024-12-12T01:21:37Z","timestamp":1733966497000},"page":"1863-1870","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Arteriovenous access creation for hemodialysis patients with superior vena cava occlusion"],"prefix":"10.1177","volume":"26","author":[{"given":"Luo","family":"Qiuping","sequence":"first","affiliation":[{"name":"Out-patient Department, West China Hospital, Sichuan University, Chengdu, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4458-9526","authenticated-orcid":false,"given":"Jin","family":"Lizhu","sequence":"additional","affiliation":[{"name":"Department of Nephrology, The Third People\u2019s Hospital of Chengdu, Chengdu, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Duan","family":"Zhiqiang","sequence":"additional","affiliation":[{"name":"The Nephrology Department of the Air Force Hospital of Western Theater Command, PLA, Chengdu, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hu","family":"Jia","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, West China Hospital, Sichuan University, Chengdu, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6922-3534","authenticated-orcid":false,"given":"Cui","family":"Tianlei","sequence":"additional","affiliation":[{"name":"Department of Nephrology, West China Hospital\/West China School of Medicine, Sichuan University, Chengdu, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2024,12,11]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1053\/j.ajkd.2022.12.001"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1097\/01.md.0000198474.99876.f0"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1053\/j.ackd.2020.03.003"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41581-020-0333-2"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1177\/11297298231197003"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1053\/j.tvir.2016.11.006"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00270-017-1787-x"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00270-018-2090-1"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1024\/0301-1526\/a000908"},{"key":"e_1_3_2_11_2","article-title":"KDOQI clinical practice guideline for vascular access: 2019 update [published correction appears in Am J Kidney Dis. 2021 Apr;77(4):551]","volume":"75","author":"Lok CE","year":"2020","unstructured":"Lok CE, Huber TS, Lee T, et al.
