Aortoiliac aneurysms: endoluminal repair--clinical evidence for a fully supported stent-graft.
OBJECTIVE
To evaluate aortoiliac aneurysms repaired with endovascular stent-grafts complicated by hemodynamically significant graft stenosis.


METHODS
Fifty-four patients (52 men, two women; age range, 41-90 years; mean age, 75 years) with aneurysms of the infrarenal aorta (n = 36) or iliac artery (n = 18) underwent repair by means of placement of an endovascular stent-graft. Technical success was evaluated angiographically during and after placement. At follow-up (range, 12-44 months), all patients underwent sequential duplex ultrasonography, helical computed tomography, and physical examination.


RESULTS
Stent-grafts were placed successfully in all cases. Stenosis at the internal iliac arterial origin was identified at angiography in 17 patients (31%). Supplemental intragraft stents were placed in 11 patients, and stent-graft angioplasty alone was performed in one patient. Intragraft stents were placed percutaneously in five patients when stenosis was discovered during follow-up.


CONCLUSIONS
Supplemental intragraft stents were required in 31% of aortoiliac endovascular stent-grafts to correct stent-graft stenosis and preserve long-term function. Placement of a fully supported stent-graft is necessary to repair an aortoiliac aneurysm.
