Novel modification of a branched arch endograft with a retrograde left common carotid branch for acute pseudoaneurysm post type A repair

Abstract

Objective

Pseudoaneurysm formation post type A aortic dissection repair is rare. Revision surgical repair is challenging, with a risk of death from haemorrhage.

Methods

We present a 56-year-old man who presented with a rapidly enlarging distal ascending aortic anastomotic pseudoaneurysm following a recent ascending and hemiarch replacement for acute type A aortic dissection.

Results

A tight kink in the ascending aortic graft precluded an endovascular repair utilizing two antegrade branches, and so a novel custom-made 3 inner branched aortic endograft was designed, with an antegrade brachiocephalic inner branch and retrograde left common carotid and subclavian artery inner branches. The patient required an angioplasty to dilate the kinked/coarcted surgical graft, but made an uneventful recovery.

Conclusion

An aortic arch inner branch design with an antegrade brachiocephalic branch but retrograde left common carotid and left subclavian branches was feasible and may prove particularly useful when there is limited space in the ascending aorta.
