Primary Covered Stent For Management Ofinfrarenalaortic and Aortoiliac Occlusive Disease; Pilot Study
Introduction: Surgery for focal infrarenal aortic stenosis or occlusive aortoiliac lesions has been the
traditional standard of care with good long-term patency rates. Numerous encouraging reports about
endovascular revascularization, mainly by using bare metal stents, on TASC II class C and D aorto-iliac
lesions were very promising regarding safety, mid-term durability. Objectives:This is a pilot study with the
assumption of non-inferiority of covered stent endovascular reconstruction for focal infrarenal aortic and
aortoiliac lesions to current endovascular bare metal stent therapy. Methods: Patients with aortic
occlusive disease ranging from isolated focal infrarenal aortic stenosis to total occlusion of the infra-renal
aorta extending or not to the iliac arteries were treated by covered stents during the period from January
2014 to December 2015. Our Exclusion criteria included: Patients with iliac occlusive diseases with no
involvement of infra-renal aorta (bifurcation only), associated extensive infra-inguinal occlusive disease,
chronic renal impairment and those with connective tissue disorders or history of previous endovascular
intervention. Results: Seven patients met our inclusion criteria, six patients (85.7%) were men. Two
patients had isolated mid infrarenal aortic focal stenosis (both were > 3 cm in length)without bifurcation
involvement. One patient had rather focal near bifurcation stenosis with length ≤ 3cm. Four patients had
chronic total aortobiiliac occlusion (TASC II D). Rest pain was the most common (57%), while minor tissue
loss (2 patients) and severe claudication (1 patient) constitute the rest of patient's presentation. Preprocedural mean resting ABIs were 0.55 ± 0.15 at the right side and 0.59 ± 0.15 at the left side. In the three
patients with focal stenosis of the aorta, mean aortic stenosis before the procedure was 70% (range, 60%-
80%). We used total of 15 stents with diameter range (8-12mm) and length range (41-61mm). Technical
and immediate clinical success were achieved in all our patients (100%) as confirmed by palpable distal
pulses, improvement of walking distance and absence of rest pain. Trophic changes were healed
completely 3- 4 months after the procedure. The immediate hemodynamic results showed mean resting
ABI to increase to 0.95± 0.05 on the right side and to 0.96 ± 0.04 on the left side. No deaths were observed
in the first 30 days. During a mean follow up of 10.5 months (range, 9-12 months), five patients had their
stented arterial segments patent (The primary patency rate at 3, 6 and 12 months were: 85%, 85% & 71%
respectively). One patient developed significant instent stenosis in one iliac stent after 3 months and was
treated balloon angioplasty using a drug coated balloon (DCB). Another patient, at 6 months follow up,
developed symptom recurrence due to tight bilateral ostial stenosis at the new bifurcation following
CERAB technique and was treated by kissing drug eluting stents (DES). At 12 months’ follow up no patient
showed symptoms of limb ischemia or recurrence of trophic changes. Conclusion:Covered stent therapy
for occlusive aortoiliac diseases is a technically feasible and potentially safe procedure that demonstrates
very good early and mid-term patency. Based on the available data, covered stents may be considered the
best and unavoidable technical solution in restoring blood flow through occluded infrarenal aorta and iliac
arteries.
