Resumen:
Purpose: To report a disconnection between the bare suprarenal stent and
the main body of a Zenith endograft. Case Report: A 79-year-old man with
a history of successful endovascular repair of an aortic aneurysm
presented a sudden episode of hypotension and hematuria. He had
undergone implantation of a Zenith bifurcated device 8 years earlier in
2006. Plain abdominal radiography and computed tomography showed
disconnection of the uncovered proximal stent, which led to endograft
migration and type Ia endoleak. The patient also presented with distal
endoleaks at the attachment sites in both common iliac arteries. The
aneurysm sac diameter had increased from 52 to 96 mm. A proximal aortic
cuff and bilateral iliac extensions were deployed via a common femoral
artery access. Completion angiography did not show endoleak. Conclusion:
After publication of a few such cases with the older Zenith device, the
union between the suprarenal stent and main body was reinforced in 2002
to prevent this complication. Since modification of the device, this
sequela had not been described. The reappearance of this complication
underscores the need for continued surveillance, considering that these
late events may require a reintervention to maintain the clinical
success of the procedure.
