Clinical studyOutcomes of Covered Kissing Stent Placement Compared with Bare Metal Stent Placement in the Treatment of Atherosclerotic Occlusive Disease at the Aortic Bifurcation
Section snippets
Materials and Methods
A retrospective review of consecutive patients from a single institution with atherosclerotic occlusive disease at the aortic bifurcation treated with kissing balloon-expandable iliac kissing stents was undertaken for procedures performed between January 1, 2002, and September 1, 2007, by using a procedural database (Hi-IQ; ConexSys, Albion, Rhode Island). Human investigation review board approval was obtained for this study. Electronic medical records were reviewed for patient demographics,
Results
Fifty-four consecutive patients were identified and divided into two groups: those with covered stents and those with bare metal stents. Twenty-six patients (17 men, 9 women; mean age, 61 years; age range, 39–79 years) received covered stents–-all of which were placed after November 2004. Twenty-eight patients (15 men, 13 women; mean age, 61 years; age range, 38–82 years) received bare metal stents–-all but four were placed before November 2004 (Table 1). The demographic data and risk factors
Discussion
The management of symptomatic atherosclerotic occlusive disease of the iliac arteries has been dramatically altered by the use of permanent metal endoprostheses (stents). Clinical success rates of 70%–92% at 2 years have been reported for bare metal stents in the CIA (21, 22). Patients with CIA origin occlusive lesions, with or without adjacent distal aortic disease, represent a complex subgroup of patients because of the technical challenges associated with stent placement and the variable

2022, Seminars in Vascular SurgeryCitation Excerpt :ABI was also noted to increase more significantly in the covered stent group, and the overall conclusion was that covered stenting yields superior outcomes. Subgroup analysis demonstrated that TASC C and D lesions showed the most benefit from this approach, and no difference was seen in TASC A/B [62–64]. The use of balloon-expandable, covered stents in the common iliac artery is our preferred strategy as well, particularly for heavily calcified lesions and those at the aortic bifurcation.

2021, Journal of Vascular SurgeryCitation Excerpt :Several previous studies have suggested reasonable short- and mid-term patency results with endovascular intervention among patients with aortoiliac occlusive disease.1,5,11,12 As stents and stent graft technology has improved, the complexity of lesions treated with endovascular intervention has also increased.3,13-15 Studies have reported that even patients with TASC C and D lesions treated with endovascular therapy have had good, durable results, similar to those after open intervention.2,6,7,16,17
