One of the major complication that affect graft survival is Vascular. This includes Vascular thrombosis, Arterial stenosis, Intra renal infarctions and Aneurysms. The Aim of the study is to evaluate the incidence and the various risk factors that would have lead to this complicaton at our center. A total of 678 renal transplants have been done during a period from November 1993 to May 2006. (487 live renal transplants and 191 cadavers). Retrospective analysis of the patient record was conducted. A total of 32 recipients were detected to have vascular complication. Among these 13 were renal artery thrombosis (1.9%), 6 were renal vein thrombosis (0.8%), 6 were renal artery stenosis (0.8%), 6 were intra renal infarction (0.8%), 1 was a mycotic aneurysm (0.14%). Of these 17 Patients had cadaver renal transplant (8.9%) and 15 had Live renal transplants. Graft loss directly attributable to the vacular complication occured in 16 patients (2.36%) The incidence of vascular complication at our centre is 4.27%. There has been a significantly higher incidence noted in cadaver renal transplant. Almost all the patients were on Cyclosporine based immuno suppresion protocol. The EGFR calculated at the time of the vascular complication was found to be low. All the patients were found to have a lower level of Hemoglobin. All these factors could be attributable as risk factors for the vascular coplication. Maintaining proper hydration in the post operative period, correction of anemia, and starting all patients who are on Cyclosporine based regimen on low dose Aspirin would reduce the incidence further.
