INTRODUCTION: Although rare (incidence of 0,1 to 8.2%), renal vein thrombosis is a major cause o early graft loss. Here we try to identify perioperative risk factors for such a catastrophic event.MATERIALS AND METHODS: We identified all cases of renal vein thrombosis in our kidney transplant database and collected the following data: Type of transplant (live vs. deceased, kidney-pancreas), graft side, presence of renal vein elongation and any special consideration that the surgeon recorded.RESULTS: From February 2010 to December 2014, 3976 consecutive kidney transplants were performed in our institution and 36 renal vein thrombosis were identified (0.9%). The diagnoses were made from postoperative day 1 to day 38 reaching a peak between day 3 and 7. Twenty nine (83,3%) were deceased donors, 5 (13,8 %) living donors and one case of pancreatic-kidney transplant. Regarding kidney side, 58% were left side grafts and 42% right side grafts. Among the right side grafts 59% underwent renal vein elongation. Only in 6 cases (15%) the surgeon reported any unusual condition that could lead thrombosis: 1 poorly perfused graft after unclamping, leading to redo of the anastomosis. 2 Stretched renal vein after positioning the kidney, leading to nephropexy in order to relive the tension on the vein. 3 Ischemic antero inferior segment of the kidney after a unrecognized ligation of polar vein and artery. 4 Reanastomose of the renal vein after compression by the ureter. 5 Severe macroscopic hematuria after unclamping. 6 Vein narrowing after elongation. Moreover only in 2 cases (5.5%) a severe hypotension was identified in the first 24 hours after the procedure.CONCLUSION: Renal vein thrombosis is a rare catastrophic complication, in our large series the incidence was 0.9%. In only 15% of the cases the surgeon perceived a possible factor that could have contributed to such event.
