[Show abstract][Hide abstract] ABSTRACT: In this prospective study we examined whether dilated common iliac arteries (CIAs) can provide a safe distal seal in endovascular aneurysm repair (EVAR) with the use of bifurcated stent grafts with large diameter limbs. Sixteen patients with 26 dilated CIAs with a diameter of > or =6 mm who were offered EVAR using stent grafts with large diameter limbs were included in the study (Group A). Forty-two patients who also underwent EVAR without iliac dilatation, matched for age, sex and surgical risk were used for comparison (controls-Group B). In group A mean CIA diameter was 18.2 mm (16-28) and mean abdominal aortic aneurysm (AAA) diameter was 6.87 +/- 1.05 cm; mean age was 77.2 +/- 4.8 yrs (67-81). Mean follow-up was 33.6 months (2.8 yrs). CIA diameter changes and development of endoleaks were assessed by CT angiography (CTA). Overall iliac dilatation was present in 16/58 of our patients (27.6%). In 10 patients dilatation was bilateral (17.3%). Partial or complete flow to the internal iliac artery (IIA) territories was preserved in all patients post-EVAR. On follow-up, stable caliber of the dilated CIAs was observed in 21 patients (84%), enlargement of 1mm in 3 (16%), and failure of the distal attachment in 1 (6.2%). Compared to the control group there was no statistical significance in the incidence of complications. Dilated common iliac arteries provide a safe distal seal in patients who have undergone EVAR, thus obviating the need for additional endovascular procedures and sparing flow in the IIA vascular bed.

[Show abstract][Hide abstract] ABSTRACT: Endovascular treatment of internal iliac artery
(IIA) aneurysms is an attractive alternative to surgical management,
because the former is associated with less morbidity and mortality.
Embolization with coils or exclusion of the IIA orifice with
stent-grafts are the preferred techniques. Although uncommon, technical
failures occur with reported aneurysm rupture. Two patients with IIA
aneurysms are reported here, where we describe successful occlusion of
their IIA aneurysms with the use of fibrin sealant, after initial
failure of coil embolization.

[Show abstract][Hide abstract] ABSTRACT: Successful endovascular correction of a 12-cm abdominal aortic aneurysm (AAA) is described in a 76-year-old man with a functional pelvic renal transplant and 18-month follow-up. Endovascular treatment is a safe alternative to surgery for AAA correction in the elderly post-transplantation patient since it does not require flow interruption during the procedure.
