 The patient had an elective EVAR procedure in 2014 for an infarinal AAA. Two years later, he developed a type IA endoleak, which required further treatment. To address this issue, the surgeons used a chimney technique, which involves placing a snorkel stent graft in the renal arteries bilaterally, extending the ceiling zone with an endovascular aortic cuff, and implanting a stent graft in the right renal artery as a periscope and a chimney in the left renal artery. Additionally, they used CO2 gas instead of iodinated contrast medium during the procedure. After five months of follow-up, there was no evidence of an endoleak, and the aneurysm sac diameter was stable. This chimney technique provides another option for treating type IA endoleaks, allowing surgeons to effectively manage these challenging cases. This article was authored by Egan L.
