Tratamento endovascular embolizante de pseudoaneurisma em rim transplantado

Abstract

Renal artery pseudoaneurysm is a vascular complication that may occur after percutaneous procedures, nephrectomy, penetrating trauma and blunt trauma, which is difficult to perform. Signs and symptoms are non-specific and may vary with each patient, with hematuria being the most common symptom. With this, it is necessary to have a good understanding of the patient’s medical history for clinical suspicion. Computed tomography and Doppler can be used as a diagnostic aid. In this report, we present the case of a patient who underwent renal transplantation with graft in the iliac vessels to the left, and progressed with worsening renal function undergoing renal biopsy. The condition progressed with a decrease in hematocrit and worsening renal function, being submitted to ultrasound with transplanted kidney Doppler showing anechoic pulsatile formation. Tomography showed contrast extravasation in the renal graft parenchyma. It was then chosen by endovascular treatment of pseudoaneurysm in renal graft with springs. The patient evolved postoperatively with resolution of left iliac fossa pain, and improved renal function.
