Multiple renal arteries and non-contrast magnetic resonance angiography In transplant renal artery stenosis

摘要

The reported incidence of transplant renal artery stenosis (TRAS), as high as 23% in earlier decades [1], ranges between 1.2 and 3.9% in more recent reports [2-5]. TRAS is a frequent cause of refractory hypertension and allograft dysfunction [5], but it is often treatable with percutaneous angioplasty. Therefore, its early recognition is critical. We describe the incidence of TRAS in our center over a 10-year period and report a case of TRAS to illustrate the complexity of the diagnosis in patients with slowly recovering graft function, multiple renal arteries and high immunologic risk for rejection. We highlight the utility of a novel non-contrast renal magnetic resonance angiography.
