Transjugular vein bypass for the treatment of hemodialysis arteriovenous fistula dysfunction caused by subclavian vein occlusion
Objective To investigate the clinical effect of transjugular vein bypass for the treatment of hemodialysis ar-teriovenous fistula dysfunction caused by subclavian vein occlusion.Methods Clinical characteristics,key points of transjugular venous bypass,and postoperative fistula function of three cases with hemodialysis arteriovenous fistula dys-function caused by subclavian vein occlusion were retrospectively analyzed.Results Transjugular venous bypass was successful in all three patients,and none of them had any related postoperative complications.Patient 1 was followed up for 9 months postoperatively,with a patent transposition vessel and good arteriovenous fistula function.Patient 2 was followed for 33 months postoperatively,with PTA twice for anastomotic stenosis;the artificial blood vessel was patency and the arteriovenous fistula function was good.Patient 3 was followed up for 15 months postoperatively,with a patent artificial blood vessel and good arteriovenous fistula function.Conclusion Transjugular venous bypass can be an option when endovascular treatment for subclavian vein occlusion is unsuccessful or risky.
