The endovascular graft components were deployed and placed according to the instruction manual.
During the post angiogram, a distal type 1 endoleak was reviewed at the distal end of the ipsilateral leg graft.
After several attempts to mold the distal end of the ipsilateral leg graft, another iliac leg graft was placed within the existing iliac leg and extended approximately five millimeters distal of the graft, very close to the hypogastric artery.
The second leg graft was ballooned and retrograde angiogram noted that the endoleak had been resolved.
Final angiogram was performed viewing only a late filling type ii endoleak from a lumbar artery.
No further intervention was deemed necessary.

The iliac leg graft was not available to be returned for the company's examination and evaluation of this reported event.
Vessels that are significantly calcified, occlusive, tortuous, or thrombus-lined may preclude placement of the endovascular graft and/or may increase the risk of embolization or endoleak.
Common iliac artery diameters greater than twenty millimeters at the expected graft/vessel distal fixation site may be prone to endoleak or continued expansion and are not indicated for placement of the endovascular graft.
Early endoleaks are thought to result from a variety of causes including improper device sizing, inappropriate pt selection, malpositioning of the endovascular graft, inadequate radial force, lack of immediate thrombosis of collateral vessels, and inappropriately high graft porosity.
Inaccurate placement and/or incomplete sealing of the zenith endovascular graft within the vessel may result in an increased risk of endoleak or migration.
Good angiography and ct imaging are paramount for accurate planning.
Careful evaluation of the pt's anatomy from the distal thoracic to the superficial femoral arteries should be made.
Endoleaks observed at the proximal or distal sealing sites may result from inadequate apposition of the graft to vessel wall at the fixation site and may be resolved by a repeat inflation of the molding balloon at the site.
If necessary additional extensions or other necessary interventional measures may need to be considered.
