A case of mycotic common iliac aneurysm in a patient with ventriculoperitoneal shunt

Aortoiliac mycotic aneurysm is an uncommon and deadly condition associated with significant perioperative morbidity. We present a case of common iliac mycotic pseudoaneurysm managed with debridement, vessel ligation, and extra-anatomic reconstruction owing to systemic illness. Notably, the patient had an implanted ventriculoperitoneal shunt for a history of cerebral aneurysm and resulting hydrocephalus. This report discusses the ultimately successful management of a large aortoiliac mycotic aneurysm. The patient did contend with bacterial meningitis postoperatively, likely owing to an ascending infection of the aforementioned shunt.
