Objectives:
The J Graft Open Stent Graft, the first commercialized stent graft in Japan, has been available since February 2014, and we have used this new device as a frozen elephant trunk technique for distal aortic arch aneurysm. Here, we present our surgical method and result with this new device.
Methods:
Between October 2014 and October 2016, 30 patients (26 males, mean age 74.3 ± 9.7 years) underwent total aortic arch replacement using the frozen elephant trunk technique with the J Graft Open Stent Graft for distal aortic arch aneurysm. The follow-up period was 10 months.
Results:
In-hospital mortality and 30-day mortality were 0%. Stroke occurred in three cases (10%), paraplegia in one case (3.3%), respiratory complication in two cases (6.7%), and renal failure in two cases (6.7%). During the follow-up period, there was no aorta- related death, and two patients needed an aortic operation (re-hemiarch replacement for pseudoaneurysm of proximal anastomotic site; axilloaxillary bypass for occlusion of the left subclavian artery), and two patients needed catheter embolization for type II endoleak for reopening of the left subclavian artery.
Conclusion:
Our short-term surgical results were acceptable. This new device is useful for distal aortic arch aneurysms.
