Abstract

Type II endoleaks are frequent after endovascular aortic repair, and recurrent endovascular failures may require open repair with high morbidity. We report a 73-year-old patient with a persistent type II endoleak managed by targeted robot-assisted retroperitoneal ligation of lumbar arteries. Dynamic computed tomography-based three-dimensional reconstructions of target vessels provided intraoperative navigation, enabling precise localization through a minimally invasive robotic approach, while minimizing procedural complications and effective management. This case demonstrates the feasibility of combining advanced imaging and robotic technology, highlighting the potential advantages of image-guided robotic surgery for complex vascular pathologies requiring innovative, definite treatment options.
