Neonatal mycotic internal iliac aneurysm due to methicillin-resistant Staphylococcus aureus (MRSA) septicaemia successfully treated by coil embolisation

A 12-day-old term male neonate presented with septic arthritis, multiple skin and intrabdominal abscesses and a mycotic aneurysin of the right internal iliac artery. He was diagnosed as having methicillin resistant staphylococcus aureus (MRSA) septicaemia and deemed unsuitable for surgical treatment of the aneurysm. Coil embolisation of the internal iliac artery was performed, followed by a successful recovery and with no evidence of residual or recurrent infection. The authors describe a method of treating internal iliac mycotic aneurysms in high-risk patients by endovascular means, which we believe has not been attempted in this precise scenario before.
