ABSTRACT
BACKGROUND:
Allograft renal vein thrombosis can cause graft loss during the early postoperative period. This diagnosis is sometimes elusive, requiring a strong suspicion. On the other hand, several authors have recognized risk factors for allograft renal vein thrombosis, but neither a preventive approach nor a treatment have been recommended for this complication. CASE PRESENTATION We present a case report of early allograft renal vein thrombosis, preceded by femoral common deep vein thrombosis in a recipient of a third kidney transplant. Despite femoral common deep vein thrombosis treatment with low-molecular-weight heparin and progressive improvement of renal function to a nadir serum creatinine of 0.51 mg/dL, the patient experienced a sudden episode of anuria on postoperative day 5. Doppler ultrasonography strongly suggested the diagnosis of allograft renal vein thrombosis. The patient underwent balloon catheter and aspiration venous thrombectomy, followed by unfractionated heparin perfusion. After 4 days of anuria and multiple blood transfusions, when allograft nephrectomy was contemplated, diuresis suddenly resumed. After 1 year of follow-up, the patient still has a normal renal function.CONCLUSION:
This case report shows successful treatment of allograft renal vein thrombosis associated with deep vein thrombosis in the first week of transplantation, using balloon catheter and aspiration venous thrombectomy followed by perfusion of unfractionated heparin. The authors suggest this technique as a treatment option for transplant renal vein thrombosis. However, they reinforce the importance of individualized treatment and they remind that a delay may jeopardize the potential benefit of the procedure.
