IntroductionIt is a controversial and difficult problem for a surgeon to manage the simultaneously occurring diseases divirticular abscess and abdominal aortic aneurysm. Mostly surgeons are not willing to execute a non vascular procedures during the repair of an aneurysm because there can be a risk of graft infection.Presentation of caseIn this case study, we have explained about the presentation of a huge infrarenal abdominal aortic aneurysm (AAA) that is found to be associated with a divirticular abscess and both needed an intervention.DiscussionIt has been suggested by various evidences that a one-stage elective surgical treatment is safer and cost effective for the treatment of patients with an abdominal aortic aneurysm associated with other problems like gastro-intestinal malignancies. However, the high risk of graft infection made the two staged procedure a popular option.ConclusionThe major dilemma is in the management of patients with large aneurysm which require an urgent repair and presented with concomitant pathologies that carry a high risk of sepsis. In this case report, we described an unusual presentation of a large aneurysm with a concomitant divirticular abscess where both needed an urgent intervention.
