External Iliac Vein Thrombosis After Renal Transplantation

We present a patient with iliac vein stenosis and thrombosis, which occurred 2 weeks after renal transplantation and were secondary to a perivascular hematic collection. The vein stenosis was identified by color Doppler ultrasonography and venography. Computed tomography demonstrated a perivascular collection. One week later, control venography identified iliac vein thrombosis. The patient underwent pharmacological thrombolysis with local infusion of urokinase for 4 hr, percutaneous transluminal angioplasty, and percutaneous installation of a metallic stent (Wallstent), with immediate favorable results. The patient remains in stable condition at 2 years after the procedure.
