| dc.description.abstract | ABSTRACT Introduction: Transplant renal artery stenosis (TRAS) is the most common preventable vascular complication in kidney transplantation with significant rates of graft loss and mortality. We aimed to study the demographics, prevalence, clinical presentation, and outcome of TRAS. Methods: We retrospectively reviewed medical records of all living donor kidney transplant recipients at Tribhuvan University Teaching Hospital from August 2008 to May 2021. Cases diagnosed with TRAS by ultrasound Doppler and/or renal CT angiogram were included. Data on demographics, clinical presentation, management, and outcomes were collected and analyzed. Among patients who underwent revascularization, pre and post-procedure creatinine, blood pressure (BP), and antihypertensive medicine burden were compared. Results: Among 620 living donor kidney transplantation, TRAS was present in 17 recipients (Male:Female = 16:1) (2.6%); mean age was 35.47±12.71 years. The median duration at diagnosis was one-month post-transplant (range: 5 days-9 months). The most common clinical features of TRAS were graft dysfunction and uncontrolled hypertension. Diagnosis of TRAS was confirmed with CT angiography in 13 patients. Ten patients underwent revascularization. Pre and post-revascularization mean serum creatinine was 356±210.49 μmol/L and 122.8±30.48 μmol/L (p=0.007) respectively, mean systolic BP was 200±12.47 mmHg and 133±13.38 mmHg (p=0.005) respectively and mean diastolic BP was 105±15.09 mmHg and 80±9.43 mmHg(p=0.005) respectively. Significant reduction in anti-hypertensive pill burden was achieved. Conclusion: Prevalence of TRAS was 2.6%. Most cases presented early with hypertension and graft dysfunction. Revascularization of significant stenosis had a favorable outcome in terms of BP control, antihypertensive pill burden, and preservation of renal function.
