Percutaneous SVC recanalization was successful in 53 cases, with a success rate of 91.38%, including 37 cases of traditional recanalization and 16 cases of sharp recanalization. Among 53 hemodialysis patients who underwent SVC recanalization, 14 patients successfully received covered stents and 38 patients received bare metal stents, achieving a stent placement success rate of 98.1%. One patient encountered stent displacement into the heart immediately after implantation, causing intra-operative cardiac tamponade, who was successfully rescued by thoracotomy. Fifty-two patients were followed-up for median period of 26 months (cuffed catheter: 25 patients, arteriovenous fistula [AVF]: 27 patients). The overall 2-year vascular access patency rate was 33.2% (cuffed catheter: 22.2%, AVF: 41.7%, p=0.414). There was no statistically significant difference in the 2-year vascular access patency rate between the traditional recanalization group and the sharp recanalization group (34.1% vs 31.1%, p=0.731) and between bare metal stent group and covered stent group (38.1% vs 21.4%, p=0.248).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Percutaneous SVC recanalization with stent placement is an effective treatment strategy that can provide viable vascular access for maintenance hemodialysis patients with SVC stenosis.

Whether stent should be implanted simultaneously following SVC recanalization is still lacking research. This pilot cohort study suggested that percutaneous SVC recanalization with stent placement was an effective treatment strategy which provides satisfactory vascular access for hemodialysis. We further found that SVC sharp recanalization with subsequent stent implantation was a feasible treatment, with the 2-year vascular access patency comparable to the traditional SVC recanalization group. This study also highlighted endovascular SVC recanalization should be performed with caution, and appropriate balloon sizes should be selected to avoid SVC rupture or stent displacement.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/15266028241283661","type":"journal-article","created":{"date-parts":[[2024,9,29]],"date-time":"2024-09-29T02:31:33Z","timestamp":1727577093000},"page":"932-939","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Stent Placement After Percutaneous Recanalization of Superior Vena Cava Stenosis in Maintenance Hemodialysis Patients"],"prefix":"10.1177","volume":"33","author":[{"given":"Yuliang","family":"Zhao","sequence":"first","affiliation":[{"name":"Division of Nephrology, Institute of Kidney Diseases, West China Hospital of Sichuan University, Chengdu, China"},{"name":"National Clinical Research Center for Geriatrics, West China Hospital of Sichuan University, Chengdu, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Caihong","family":"Liu","sequence":"additional","affiliation":[{"name":"Division of Nephrology, Institute of Kidney Diseases, West China Hospital of Sichuan University, Chengdu, China"},{"name":"National Clinical Research Center for Geriatrics, West China Hospital of Sichuan University, Chengdu, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Wei","sequence":"additional","affiliation":[{"name":"Division of Nephrology, Institute of Kidney Diseases, West China Hospital of Sichuan University, Chengdu, China"},{"name":"National Clinical Research Center for Geriatrics, West China Hospital of Sichuan University, Chengdu, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3363-5649","authenticated-orcid":false,"given":"Tianlei","family":"Cui","sequence":"additional","affiliation":[{"name":"Division of Nephrology, Institute of Kidney Diseases, West China Hospital of Sichuan University, Chengdu, China"},{"name":"National Clinical Research Center for Geriatrics, West China Hospital of Sichuan University, Chengdu, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2024,9,28]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1055\/s-0041-1742152"},{"key":"e_1_3_2_3_2","article-title":"A systematic review and meta-analysis of 24 month patency after endovenous stenting of superior vena cava, subclavian, and brachiocephalic vein stenosis","volume":"5884","author":"Chawla S","year":"2024","unstructured":"Chawla S, Zhang Q, Gwozdz AM, et al.
