Background: This article describes a chimney technique (ChEVAR) to preserve the patency of the inferior mesenteric artery (IMA) in a patient with abdominal aortic aneurysm (AAA) and bilateral internal iliac artery obstruction. In addition, a review of the literature is performed. Case report: This article describes a male in his 70s with multiple comorbidities and a 5.6 cm infrarenal aortic aneurysm. CT scan showed bilateral iliac internal artery obstruction with compensatory hypertrophy of lumbar arteries along with a 6 mm inferior mesenteric artery. We planned a staged treatment: embolization of lumbar arteries to prevent type 2 endoleak as a first step, followed two months later by standard EVAR with chimney graft to maintain patency of IMA. The postoperative course was uneventful. The endograft was widely patent on CT scan at his 6-month follow-up visit. Conclusions: ChEVAR to preserve the patency of IMA is a feasible and valid technique that could be considered in the case of bilateral hypogastric obstruction.
