Iliac Branch Device for Infrarenal Aortic Dissection: A Novel Off-Label Strategy

Infrarenal aortic dissection is a rare condition, and the presence of a triple lumen has been described as a marker of instability and poor prognosis.We report the case of a 56-year-old woman with infrarenal dissection and triple lumen who presented with refractory abdominal pain.Due to hostile anatomy, conventional endografts were unsuitable.An iliac branch device was used offlabel as the main body, achieving complete reconstruction and preservation of bilateral iliac flow.This case expands previous off-label applications of iliac branch devices, demonstrating feasibility in infrarenal dissection beyond aneurysmal or occlusive disease.
