Results
Technical success (coverage of the primary tear) was 99.35%.
There were two cases with a type I endoleak at the end of the procedure,
which defined as blood flow into the false lumen (FL) due to incomplete seal or ineffective seal at the extremity of the stent graft.
In-hospital and 30-day rates of death,
endoleak,
stroke,
and retrograde type A aortic dissection were 0.6% (n=2),
9.7% (n=30),
0.6% (n=2),
and 1.3% (n=4),
respectively.
The direct death cause of two patients was a new rupture of the aorta.
One of them had a persistent fever and poor blood pressure control after operation.
In another case,
a retrograde type A aortic dissection was detected by computed tomography angiography on day 27 after the operation.
Median follow-up time was 35.20±24.09 months (range,
3 to 126 months).
Overall survival was 98.0%,
87.7%,
and 77.7% at 1,
5,
and 10 years’ follow-up.
The rates of late endoleak and complete false lumen (FL) thrombosis were 10.6% and 73.9%,
respectively.
Furthermore,
12 patients received re-intervention therapy. Endovascular repair was performed again in two new thoracic or abdominal aortic dissections and seven endoleaks (6 type I endoleak and 1 type III endoleak). Two cases with a new rupture of the aneurysm and one case with a retrograde type A aortic dissection underwent surgical treatment.
No postoperative spinal cord ischemia (SCI) and paraplegia was observed.
