  • Title: Technical tips for endovascular repair of common iliac artery aneurysms.
    Author: Buckley CJ, Buckley SD.
    Journal: Semin Vasc Surg; 2008 Mar; 21(1):31-4. PubMed ID: 18342733.
    Abstract:
    Isolated common iliac artery aneurysms are rare, comprising <2% of all aneurysm disease. These aneurysms present as either isolated disease, .03% of the population, or, in conjunction with abdominal aortic aneurysm, in approximately 20% to 25% of such cases. Common iliac artery aneurysms are defined as any localized dilatation of the common iliac artery >1.5 cm in diameter. Elective repair for isolated common iliac artery aneurysms is generally not undertaken for aneurysms <3 cm in diameter unless they are part of an abdominal aortic aneurysm repair. Most common iliac artery aneurysms are found incidentally during abdominal/pelvic diagnostic imaging studies or at the time of pelvic or abdominal surgery. As with abdominal aortic aneurysms, endovascular repair of common iliac artery aneurysms follows techniques similar to those used for endovascular repair of abdominal aortic aneurysm. Management includes aneurysm exclusion with an endograft, which seals at sites within the proximal and distal common iliac artery and may involve coil occlusion of the hypogastric artery with extension of the reconstruction into the proximal external iliac artery, or use a "bell-bottom" endograft limb placed at the common iliac bifurcation. Technical tips for successful outcome are described here, and all US Food and Drug Administration approved endografts have been used for repair. There were no statistically significant differences in outcomes that correlated with device or repair techniques used for management of common iliac artery aneurysms. Mid-term 54-month outcome has been excellent, with no common iliac artery ruptures or aneurysm-related deaths and the need for secondary interventions was gratifyingly small.
