Endovascular repair of aneurysmal pathology in the aorto-iliac district presents one of the significant challenges in contemporary vascular surgery. Advances in techniques, materials, and devices have enhanced the ability of vascular surgeons in endovascular procedures, leading to the management of increasingly complex cases, with applications sometimes extending beyond the Instructions for Use (IFUs) of specific devices. In our case report, we describe the successful endovascular retrieval of a disconnected tip from an iliac branch device (IBD), preventing conversion to open surgery in a 73-year-old patient with a complex aortoiliac aneurysm. The case highlights the importance of exercising caution when treating patients with complex anatomy not in conformance with a device's IFU, even in high-volume centers with extensive endovascular expertise.
