Physician modification of a Gore endograft for accessory renal artery preservation

Year: 2026

Type: article

Abstract: ) who presented with a 5.5-cm infrarenal abdominal aortic aneurysm with gradual growth on surveillance. The infrarenal neck measured 22 to 24 mm in diameter and 27 mm in length, with circumferential wall calcification and atheroma. Two accessory renal arteries originated in the middle of the seal zone, each supplying a significant proportion of the renal parenchyma. The main renal arteries were small (4.1/4.2 mm at the origin) and somewhat diseased with ostial calcification. Open repair with possible suprarenal clamp was considered higher risk for renal dysfunction. Endovascular aneurysm repair using a physician-modified endograft with fenestrations created using a punch biopsy device was performed. The procedure was technically successful, with no type I or III endoleak and no change in the estimated glomerular filtration rate at the 2-month follow-up.
