We present a 78-year-old female with end-stage renal disease on hemodialysis via a right brachio-basilic arteriovenous fistula. She had previously undergone numerous fistulograms and endovascular interventions for right upper extremity swelling due to prolonged bleeding following dialysis. After a recent fistulogram she developed recurrent arm swelling. Duplex showed a large hematoma without any evidence of vascular flow. However, intraoperatively, she was noted to have a giant 20 × 35 cm pseudoaneurysm of the brachial artery. Therapeutic options include endovascular stenting, embolization, thrombin injection, ultrasound-guided compression, and surgery. We elected to perform resection of the large pseudoaneurysm and arteriovenous fistula ligation due to the large size. Given her end-stage renal disease status and lacking quality autogenous vein, we were able to perform a patch angioplasty repair of her brachial artery without requiring a bypass.
