    Our aim was to study the long-term outcomes of all transplant recipients who underwent angiography for suspected TRAS at our institution. The patients were divided into TRAS+ve and TRAS−ve groups based upon angiographically confirmed results. TRAS was confirmed in 58.1% of 74 patients with median time of 8.9 months. Primary angioplasty alone was performed in 56% of patients with TRAS, while the remaining had PTA with stent (PTAS). There was reduction in systolic and diastolic BP (165 ± 19–136 ± 15 mmHg and 82 ± 14 mmHg to 68 ± 12 mmHg; p < 0.05) and number of antihypertensive drugs (3.5 ± 0.9–2.7 ± 1.0; p < 0.05). Overall, graft survival and patient survival from time of transplant were similar in both groups. Graft function was similar for the patients with treated TRAS+ve as compared to TRAS−ve over time. Graft survival and patient survival when compared to an age- and year of transplant-matched cohort control group were also similar. In conclusion, angiography for suspected TRAS is more likely to yield a confirmatory result early in the transplant course as compared to late. Treatment of TRAS in these patients had sustained long-term graft function. Alternative etiologies of HTN and graft dysfunction should be sought for recipients further out from transplant.
