OBJECTIVE: Most of the entry tears of uncomplicated type B aortic dissection are located in the distal arch and extends in a retrograde manner to the level of the left subclavian artery. Our objective was to evaluate feasibility and effectiveness using fenestrated sent graft with complete neck vessel preservation to treat uncomplicated type B aortic dissection.
SUBJECTS AND METHODS: We retrospectively reviewed the record of patients with uncomplicated type B aortic dissection who underwent fenestrated thoracic endovascular aortic repair in subacute phase (15-90 days) between August 2016 and April 2020. The Najuta fenestrated stent graft was placed proximally beyond he left subclavian artery (zone 0-2) in an attempt to seal the entry while preserving the neck vessels.
RESULTS: We evaluated 9 cases (male: 7, female: 2; median age 70 years). The median distance from the LSA to the proximal entry was 37 mm. The landing zones of the proximal end of the Najuta were zone 0: 3, zone 1: 2, and zone 2: 4 cases. Technical success was 100% with no 30-day death. None of the patients had a stroke, paraplegia or retrograde dissection, and no endoleak was observed. Complete aortic remodeling with false lumen resolution was obtained in all cases while each fenestrated vessels remained patent during the follow-up period.
CONCLUSION: Preemptive thoracic endovascular aortic repair aimed at perfusion of cervical branches using the Najuta fenestrated stent is safe and effective and may be considered as a reasonable treatment option for the treatment is a safe and an effective treatment.
