OBJECTIVES: Endovascular stent grafts (SGs) comprise a novel therapeutic approach to repairing aortic aneurysms. However, endovascular repair of the aortic arch remains challenging. Generally, the repair of sites with SGs requires an extra-anatomical bypass. We introduced SG repair of the aortic arch with strategically positioned fenestrations for each arch branch in 2006. An extra-anatomical bypass is not required for this procedure. This study evaluates the early and mid-term outcomes of fenestrated SG treatment. METHODS: We retrospectively analysed the early and mid-term outcomes of 24 of 80 repairs with fenestrated SG among 383 single thoracic aortic aneurysm repairs that were undertaken at our department between January 2006 and March 2012. RESULTS: Technical success was obtained in 100% of the patients. However, there was a 30-day perioperative mortality rate of 4.1% (1 of 24) due to a shower embolism. One patient developed a Type 2 endoleak without aneurysm enlargement within a median follow-up time is 25.1 months. However, migrations or device-related complications requiring additional procedures did not arise. CONCLUSIONS: Treatment with fenestrated SGs does not require surgical transposition of the arch branches. The procedure is widely applicable and less invasive and outcomes are excellent.
