Abstract
BACKGROUND: We describe the technical operative details of the robotic repair of a type II endoleak (T2E) following endovascular abdominal aortic aneurysm repair (EVAR). We demonstrate that indocyanine green (ICG) can be used intra-operatively to demonstrate perfusion of the colon following ligation of the inferior mesenteric artery (IMA) vessel feeding the aneurysm sac. METHODS: A 74-year old male underwent EVAR for a 5.8 cm infra-renal abdominal aortic aneurysm using an E-Tegra, Jotec Device (JOTEC Gmb, Lotzenäcker 23,D-72379 Hechingen). Surveillance contrast CT (CTA) over the ensuing 30 months confirmed progressive sac expansion. RESULTS: ICG confirmed colonic perfusion via the marginals after IMA ligation. Total operative time 56 min < 50 mls blood loss and 1-day hospital stay. 3-month follow-up: CTA and ultrasound demonstrated complete resolution of T2E and adequately perfused colon. CONCLUSION: A total robotic approach can be performed safely with intra-operative ICG used to demonstrate colonic perfusion as an added safety measure.
