[Vascular trombosis of renal graft: 9 cases].

BACKGROUND: Allograft renal thrombosis can occur in 1 to 6% of cases. Many predisposing factors has been identified especially alteration of coagulation. AIM: We analyzed in this study frequency and predisposing factors of renal graft thrombosis. METHODS: We report a retrospective study including 319 renal transplant recipients. RESULTS: Nine patients (2.8%) presented veinous graft thrombosis in 5 cases and arterial thombosis in 4 cases. There were 6 men and 3 women aged of 30.6 years meanly (10-56) which developed the thrombosis 6 days (1-48) after the transplantation. All patients were detransplanted after 16.2 days and 1 patient died. CONCLUSION: Thrombosis constitute an important cause of graft loss. A perfect surgical technic and prophylactic treatment in high risk patients are necessary to reduce this complication.
