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. Owing to hostile anatomy, conventional endografts were unsuitable. An iliac branch device was used off-label 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.
