Bail-out coil embolization for a pseudoaneurysm of aortic sinotubular junction in a patient with Behcet's disease after receiving multiple aortic operations

Transcatheter repair of a pseudoaneurysm of the aortic sinotubular junction with coils is quite challenging because it can cause coronary or systemic embolization of coils and aortic rupture. A 71-year-old female patient with Behcet's disease who had received repeated surgical aortic repairs presented with a complicated pseudoaneurysm. It developed not on the native aorta, but on the ascending aortic graft. It was positioned just beside the os of the attached trifurcated vascular graft trunk connecting arch vessels. To avoid reopening the sternum, which would have been fatal, coil embolization was successfully performed. This case suggests that transcatheter coil embolization might provide an alternative treatment option for such patients with a high risk of surgical mortality.
