Percutaneous device closure of a massive pseudoaneurysm of the descending aorta in a paediatric patient with Takayasu arteritis

Takayasu arteritis (TA) is commonly known as a disease of young women, highly prevalent in Asia and Central America, and associated with multiple vascular complications. Although it is well described in the paediatric population, severe complications are rarely seen.

A multidisciplinary discussion concluded that this pseudoaneurysm carried a high mortality risk with a direct surgical approach. This case report describes the use of an Amplatzer
