Introduction: Kissing stent technique can be applied for endovascular treatment of aortoiliac steno-occlusive disease. Only a few data exist about the long-term patency of stents and the predisposing factors for restenosis development.
Aims: To determine long-term patency rates of kissing stents and to identify predisposing factors for restenosis development.
Method: 108 patients [67 females, median age: 61 (55.5-69) years] with symptomatic aortoiliac steno-occlusive disease who underwent kissing stenting of the iliac arteries between 2001 and 2015 at our Department were retrospectively analysed. Symptoms, atherosclerotic risk factors, comorbidities, anatomic variations of the aortic bifurcation, lesion characteristics, and balloon/stent parameters were examined. Follow-up consisted of clinical exams and duplex scans. Kaplan-Meier analysis, Mann-Whitney U test, Fisher’s exact test, and multivariate logistic regression were performed.
Results: 216 stents (12% balloon-expandable, 88% self-expandable) were deployed in 108 patients (Fontaine IIA: 3%, IIB: 81%, III: 7%, IV: 9%; TASC A: 56%, B: 24%, C: 2%, D: 18%). The median follow-up time was 65 (36-126.5) months. The primary patency rates were 97%, 95%, 91%, 85%, and 81% at 6, 12, 24, 60, and 120 months, respectively. Symptomatic restenosis/reocclusion developed in 17 patients (16%). Restenosis rate was significantly higher among younger patients (p=0.0012), and (irrespectively of age) in cases with mismatch between balloon/stent and vessel diameters [sum of balloon and sum of stent diameters exceeded the aortic diameter (p=0.0017 and p=0.0149)], and in patients with high aortic stent length/iliac arterial stent length ratio (right side: p=0.0065, left side: p=0.0331).
Conclusion: Kissing stent technique can be used with good patency rates for endovascular treatment of the aortoiliac steno-occlusive disease. Age, balloon and stent parameters seem to have an impact on restenosis development.
