Introduction: Vascular complications following renal transplantation are important cause of graft dysfunction and loss in early post-transplant period and have significant negative influence on graft survival. Aim: To determine the incidence of vascular complications that occurred within 6 months post transplantation period, its clinical presentation and outcome in our centre and to discuss on relative role of each imaging techniques in detection of vascular complications. Material and Method: This is a retrospective study of a cohort of 2667 consecutive renal transplant over a period of 8 years in Institute of Kidney Diseases and Research centre from 1^st January 2010 to 30^th December 2017. All patients underwent colour and duplex Doppler ultrasound examination on the 1^st postoperative day, in conditions of decreased or absent urine output, altered serum creatinine or other biochemical parameters. Further radiological investigations were performed as and when necessary. Results: Out 0f 2667; 2190 transplants were living donor renal transplantation and 477 were deceased donor transplantation. During 6 months post-transplant period; vascular complications were found in 39 patients. (Incidence: 1.46 %); out of these; 30 were living and 9 were deceased donor transplantation. We found no significant statistical difference in incidence of vascular complication between live and deceased donor transplantation. We found renal artery stenosis was most common vascular complication and Rise in serum creatinine was most common presenting symptom. Out of 39; 21 grafts were salvaged by appropriate treatment. (51.28%) Conclusion:Awareness of different radiological imaging appearance played a key role in diagnosis of vascular complications. Immediate diagnosis and early intervention of vascular complication could salvage the graft.
