[Simultaneous urokinase perfusion in renal artery and vein in a case of renal vein thrombosis].
We present he case of a young man with nephrotic syndrome, caused by membranous glomerulonephritis, who developed renal vein thrombosis with extension to the inferior vena cava is presented. Renal vein thrombosis was diagnosed by echo Doppler and confirmed by angio-CT scan. At the hospitalization the patient presented a severe left flank pain, edema of the lower limbs and painful left testicular tumefaction. The treatment consisted of: 1) systemic anticoagulation with sodic heparin, 2) placement of temporary vena cava filter through the right jugular vein, 3) direct thrombolysis into endocaval thrombus with early lysis of thrombus, and 4) renal thrombolysis with selective simultaneous renal artery and renal vein infusion of urokinase. Angiography performed after 24 hours of loco-regional thrombolysis showed complete lysis of renal thrombus; clinically there was a regression of left flank pain. We conclude that, face to renal vein thrombosis, thrombolytic treatment with simultaneous renal artery and renal vein perfusion is mandatory. Furthermore it is very important, in presence of caval extension of renal thrombus, to place a temporary vena cava filter before starting thrombolysis, considering the high risk of pulmonary embolism related to this pathology.
