Abstract
BackgroundKidney transplantation is the preferred treatment option for eligible patients with end-stage renal disease. With the advanced transplantation technology and the novel immunosuppressive agents, kidney transplant recipients survive significantly longer. But the chance of developing malignant tumors has increased, posing a serious challenge to the survival of transplanted kidneys and patients. Case presentationWe report a male patient (the patient's informed consent has been obtained) who underwent kidney transplantation 23 years ago. Subsequently appeared transplant renal artery stenosis (TRAS) , primary renal clear cell carcinoma(RCCC), and papillary thyroid cancer(TC). The narrowed blood vessels were dilated through percutaneous transluminal angioplasty (PTA), and the malignant tumor was removed surgically. Currently, anti-rejection drugs are regularly taken, and the transplanted kidney function is good. Satisfied with living conditions. ConclusionHypertension that is difficult to control after kidney transplantation should be suspected as a possibility of graft vascular stenosis. When B-ultrasound cannot accurately diagnose it, magnetic resonance angiography should be used as early as possible to clarify the diagnosis and relieve the stenosis before graft dysfunction. Transplantation patients have a high incidence of malignant tumors after surgery, and the risk increases with the prolongation of the disease course. Focus on symptomatic treatment of related diseases, and anti-rejection drugs can be reduced or not reduced as appropriate.
