Outcomes of hand-made versus commercial stent grafts in frozen elephant trunk

The frozen elephant trunk (FET) technique is effective for treating extended aortic arch aneurysms. This study compares hand-made and factory-made devices in this context.

Description
Summary:The frozen elephant trunk (FET) technique is effective for treating extended aortic arch aneurysms. This study compares hand-made and factory-made devices in this context. A retrospective case-control study was conducted on 68 patients who underwent FET for distal aortic arch aneurysm at our institution. We used two different types of devices: hand-made stent graft in group Z (17 cases, 25.0%) and a commercialized stent graft in group J (51 cases, 75.0%). The study compared demographic characteristics and the outcomes between the two groups. In-hospital mortality was equivalent in both groups (5.9%). Spinal cord injury rates were 5.9% in group Z and 3.9% in group J. Group Z had a higher rate of aortic events (55.9% vs 96.9%,
