    Abstract:
    BACKGROUND: Pre-manufactured branched grafts now allow an endovascular approach to the repair of thoraco-abdominal aortic aneurysm (TAAA) with visceral vessels' involvement. Similar grafts have been employed in open surgery, generally as a second choice for TAAAs, which are not amenable to patch/inclusion technique for visceral vessel attachment. Results with branched grafts have not been reported in series of open TAAA repairs. The purpose of this report is to describe perioperative risks and outcomes in a consecutive series of patients with pre-manufactured side-branched thoracoabdominal aortic grafts (STAGs) for surgical TAAA repair. METHODS: Between 1996 and 2009, pre-manufactured STAGs were used in 50 patients with TAAA that required reattachment of the visceral and renal arteries. Operative details, perioperative mortality and ischaemic complications were examined. RESULTS: Mean age was 53 years; 18 patients were females. The cases included redo (n = 24), patients affected by genetic disorder (Marfan) (n = 20) and patients with aortic dissection (n = 27). The mean clamp time was 84.1 min. Perioperative mortality was 12.0% (6/50). Neurologic deficits occurred in 2% (1/50). Postoperative renal dysfunction was detected in 19 patients (38%). CONCLUSION: The use of a STAG produced acceptable mortality, bowel and neurological ischaemic risks. Improved strategies to prevent renal ischaemia before and during repair of TAAA with visceral involvement are needed.
