Saccular Infrarenal Abdominal Aortic Aneurysm following Scrub Typhus Infection: A Rare Vascular Complication Managed with Endovascular Repair

To report a rare case of a saccular infrarenal abdominal aortic aneurysm (AAA) that developed following scrub typhus infection and was managed successfully with endovascular stent-graft repair. A 45-year-old man with a recent history of scrub typhus complicated by acute kidney injury presented with progressive left lower abdominal pain. Contrast-enhanced computed tomography revealed a saccular infrarenal AAA along the left margin of the infrarenal abdominal aorta with mural hematoma. Laboratory investigations showed increased inflammatory markers. The patient underwent endovascular aortic aneurysm repair with a Medtronic Endurant II stent graft. Postprocedure imaging confirmed complete isolation of the aneurysm with no leak. The postoperative period was uneventful, and follow-up visits showed no recurring symptoms in the short term. Scrub typhus, though primarily associated with vasculitis and perivasculitis, can rarely affect large arteries. This case highlights the need to consider aortic involvement in patients with persistent symptoms following scrub typhus infection.
