Active bleeding after kidney biopsy: Successful ultrasound‐guided direct thrombin embolization into the cortical fistula

Abstract

A 27-year-old man, previously diagnosed with IgA nephropathy, was referred for native kidney biopsy. After the procedure, the patient presented active bleeding revealed by Doppler and contrast-enhanced ultrasonography at the biopsy site. Successful embolization of the cortical fistula, the focus of bleeding, was achieved using
