Infectious aneurysm of the cavernous carotid artery in a child treated with a new-generation of flow-diverting stent graft: case report

Abstract

Objective: To report a unique case of wide-necked mycotic cerebral aneurysm treated with a new generation of intracranial stent.

Clinical presentation: A 10-year-old girl presented with meningitis complicated by an infectious intracavernous large aneurysm revealed by cranial nerve palsy.

Intervention: The aneurysm was treated by a new-generation, flow-diverting, endoluminal implant (SILK; BALT EXTRUSION, Montmorency, France) placed across the aneurysm neck without coiling. Angiographic controls showed complete thrombosis of the aneurysmal sac with dramatic improvement of symptoms a couple of weeks after the procedure. Follow-up magnetic resonance imaging and digital subtraction angiography 3 months after the procedure, confirmed total occlusion of the aneurysm with normal circulation in the parent vessel

Conclusion: This is a simple and highly effective way to exclude an aneurysm from the parent vessel without the difficulties observed with the semi-rigid stents. Flow-disrupting stent grafting may be a safe and effective alternative treatment for large intracranial aneurysms.
