Abstract Background and Aims Transplant Renal Artery Stenosis (TRAS) is a vascular complication after kidney transplantation. It worsens the prognosis of the graft and the patient's life. The aim was to study the incidence of TRAS as a cause of resistant arterial hypertension in kidney transplant recipients in the Republic of Belarus and the efficiency of its endovascular treatment. Method The study included 187 kidney transplant recipients. Blood pressure of 72 (38.5%) patients was less than 130/80 mmHg without taking antihypertensive drugs. Arterial hypertension was diagnosed in 115 (61.5%) recipients. The study included clinical, laboratory and instrumental methods (24-hour blood pressure monitoring, Doppler ultrasound, graft scintigraphy with captopril). Results 31 (16.6%) recipients needed to take one antihypertensive drug, 43 (23.0%)—2 drugs, 41 (21.9%)—3 or more. 17 (9.1%) recipients did not have target blood pressure correction while taking more than 4 antihypertensive drugs. There was decreased blood flow in the graft artery with a peak systolic velocity > 200 cm/s in 14 (7.5%) cases. These patients were submitted to the graft nephroscintigraphy with caplopril where 8 grafts (4.3%) were diagnosed signs of TRAS. These recipients were submitted to the renal angiography with the injection of 150 (100; 200) ml of contrast agent. 5 (2.7%) recipients were diagnosed with hemodynamically significant TRAS of more than 70 (65; 75) % and received percutaneous transluminal angioplasty and stenting. All these patients had a decrease of glomerular filtration rate and resistant arterial hypertension before operation. The average age of the patients with TRAS was 57.4 ± 11.0 years, the period after transplantation was 11 ± 3 months. Their blood tests did not show dyslipidemia, but 4 out of 5 cases had diabetes mellitus. Their postoperative period had no complications. The patient was placed on dual antiplatelet therapy with aspirin and clopidogrel. There was an increase in glomerular filtration rate by 27 ± 7 ml/min/1.73 m2 and a decrease in systolic blood pressure by 40 (40; 45) mm Hg in the early postoperative period. Graft artery stenting allowed reducing the number of antihypertensive drugs to one tablet in 4 out of 5 patients. Conclusion Transplant Renal Artery Stenosis is a rare but significant complication of the late postoperative period that may cause resistant hypertension in kidney transplant recipients. Timely identification and stenting of the graft artery improves the graft functioning and reduces blood pressure.
