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

## TL;DR

This paper reports a rare case of a mycotic aneurysm in a patient with a ventriculoperitoneal shunt, highlighting successful treatment and postoperative complications.

## Contribution

The novelty lies in managing a complex mycotic aneurysm in a patient with a pre-existing shunt, leading to insights in surgical and postoperative care.

## Key findings

- The patient's mycotic aneurysm was successfully managed with debridement and reconstruction.
- Postoperative bacterial meningitis was likely due to shunt-related infection.

## Abstract

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.
