PURPOSE: This study sought to assess the feasibility and effectiveness of hybrid treatment of isolated aortic arch aneurysms. MATERIALS AND METHODS: Between December 2000 and December 2006, we selected 14 patients affected by 14 isolated aortic arch aneurysms. All patients had involvement of the left subclavian artery, four of the innominate artery and four of the left carotid artery. All patients underwent intentional exclusion of the left subclavian artery and placement of a straight graft; four patients underwent supra-aortic vessel transposition and four underwent carotid-carotid bypass in one case combined with carotid-subclavian bypass. The procedures were planned with multislice computed tomography (MSCT), in some cases associated with virtual endoscopy. The follow-up was performed with MSCT angiography at 1, 3, 6 and 12 months and yearly thereafter. RESULTS: Immediate technical success was achieved in 100% of cases. There were four ischaemic attacks (three transient ischaemic attacks and one stroke). During follow-up (range 12-48, average 21 months), we observed two type-I endoleaks that were treated by endograft extension, in one case associated with supra-aortic vessel transposition, and two type-II endoleaks that were treated with embolisation. CONCLUSIONS: Hybrid treatment for aortic arch aneurysms is feasible and provides good short-term results, although it requires accurate planning. Further studies are needed to verify the long-term results.
