Background Transplant renal artery dissection (TRAD) is a rare and serious event that can cause allograft dysfunction eventually graft loss. Most cases are managed by operative repair. We report case of TRAD in the early postoperative period, which was successfully with intravascular ultrasound-assisted endovascular intervention. Case presentation A 38-year-old man underwent HLA-compatible living kidney transplantation. The had one vein, were anastomosed to internal iliac external respectively. Doppler ultrasonography performed day after operation showed an increase systolic blood velocity, no observed urine output raising suspicion arterial anastomotic stenosis. Angiography donor distal moderately stenosed anastomosis site calcified atherosclerotic plaque confirmed IVUS. transplant lesion intervened stent. After intervention, US revealed flow adequate without velocity. Urine gradually returned 3 weeks, serum creatinine level normalized 2 months. Conclusions recipients commonly have atherosclerosis hypertension, risk factors for dissection. Our intervention replace surgery repair very vascular complications such as help patients avoid high-risk operations. Early diagnosis IVUS-assisted experienced interventionists save dysfunction.
