IntroductionHybrid aortic arch repair for the treatment of aorto-bronchial fistulas has been suggested as a safe alternative to open repair. However, surgical morbidity and mortality are still significant and re-intervention is sometimes inevitable.ReportSuccessful rescue by a hybrid approach is reported in a 76 year old woman who was transferred from another centre with recurrent episodes of left hemiplegia shortly after debranching of the supra-aortic vessels and thoracic aortic stent grafting for an aorto-bronchial fistula associated with a true aneurysm at the level of origin of the left subclavian artery. Investigation revealed partial coverage of the ostium of the brachiocephalic artery and Type Ib and II endoleaks. In the first stage a chimney graft was put into the brachiocephalic trunk, and in the second stage the left subclavian artery was plugged and the thoracic stent graft was extended distally. Completion angiography showed restoration of the supra-aortic blood flow and no residual endoleaks. After 1 year follow up the patient was doing well with no recurrent neurological events and no signs of infection.DiscussionProcedure related problems should be suspected first when early post-operative complications occur after a hybrid aortic arch repair. The chimney graft technique is a valuable option for unintentional covering of a critical supra-aortic branch. Nevertheless, the importance of precise positioning during initial thoracic stent graft placement should be emphasised.
