Abstract
Aim:
The fenestrated Anaconda custom-made stent graft is one of the recently widely accepted fenestrated devices for managing complex juxta- and pararenal aortic pathology. This study showed its feasibility for treatment of challenging juxtarenal anatomy of the abdominal aorta.
Methods:
Over the period of 12 months, 9 patients with juxtarenal aortic aneurysm underwent fenestrated stent graft implantation in our institution. The graft fenestrations were customized on the basis of computerized tomography (CT-Angiography; CTA). Selected visceral ostia were protected with covered balloon-expandable stents after partial stent graft deployment. The perioperative and short term data were collected prospectively.
Results:
The mean aneurysm diameter was 58.4 mm (range 46-73 mm). The mean infrarenal neck length was 3.5 mm (range 0-7 mm), no patient had a severe (>60°) angulation of proximal neck. 18 fenestration for renal arteries, 1 for SMA and 3 for coeliac´s were treated with Advanta V12 covered stent. All the target vessels were cannulated successfully through fenestrations and all the stent grafts were successfully deployed in patients with no technical issue in the release mechanism. All the patients have undergone 6 month follow-up, no aneurysm related or aneurysm-unrelated deaths were reported. On the CTA scan, 3 of the patients had a weak type IIb endoleak; no type I or Type III endoleak was demonstrated. All target vessels were open without an instance of branch-stent stenosis/occlusion. No reintervention was needed.
Conclusion:
The usage of custom-made Anaconda fenestrated stent graft for endovascular treatment of juxtarenal aortic aneurysms is feasible with acceptable intermediate-term results.
