Recurrent gastrointestinal bleeding with ANCA Associated Glomerulonephritis successfully treated by transarterial embolization

Anti-neutrophil cytoplasmic antibody-associated vasculitis (aav) is a group of autoimmune diseases that normally affects multiple organs. recurrent gastrointestinal (gi) bleeding, a critical complication of aav, remains a challenge. here, we report a case of aav complicated by pulmonary hemorrhage, severe recurrent gastrointestinal bleeding, and rapid progressive renal insufficiency that was treated successfully with selective transarterial embolization, continuous veno-venous hemofiltration, plasma exchange, intravenous gamma globulin infusion, followed by steroids and cytotoxic drug therapy. we report this case considering that selective transarterial embolization may be a safe and effective alternative method in recurrent aav associated gi bleeding caused by aav refractory to medical therapy.
