Post-operative Recurrent Ascending Aortic Pseudoaneurysm with Aorto-cutaneous Fistula- Endovascular management with an In-situ Stent-Graft Fenestration for the Innominate Artery.

Ascending aortic pseudoaneurysm is a known complication of previous cardiac surgery that needs surgical or endovascular intervention. The presence of arch branches complicates the later approach necessitating additional procedures, either hybrid surgical or endovascular modification of the grafts. We describe a patient who developed an ascending aortic pseudoaneurysm after mitral valve replacement, which recurred after surgical patch closure with the formation of a cutaneous fistula. This high-risk patient was managed by an endovascular approach with in-situ fenestration for the innominate artery by a simple technique.
