Percutaneous thrombus aspiration in renal artery stenosis after renal transplantation

, : Percutaneous thrombus aspiration in renal artery stenosis after renal transplantation. Revista Portuguesa de Cardiologia 31(12): 803-808

We describe the case of a patient with chronic renal failure under hemodialysis for five years who, after renal transplantation, developed acute renal failure and hypertension refractory to medical therapy. Given the clinical and imaging (renal ultrasound and computed tomography) suspicion of renal artery graft thrombosis, invasive angiography was performed, which confirmed the diagnosis. The therapeutic approach consisted of percutaneous thrombus aspiration and subsequent balloon angioplasty of the entire artery, followed by stent implantation in a second procedure. The clinical course was uneventful with improvement of renal function and normalization of blood pressure. The case highlights the importance of percutaneous intervention in the management of patients with vascular complications after transplantation, with successful application of a procedure normally used in the setting of acute myocardial infarction - percutaneous thrombus aspiration and implantation of a drug-eluting vascular stent.
