- Abstract:
- BACKGROUND: The performance of endovascular stent-graft placement in patients suffering from aneurysms involving the descending aorta originating from chronic type B dissections is unclear. METHODS: Within a 2-year period, we treated 6 patients with this pathology. Four patients required extension of the proximal landing zone (autologous double transposition, n = 2; subclavian-to-carotid artery transposition, n = 2) before stent-graft placement. RESULTS: Supra-aortic rerouting procedures and endovascular stent-graft placement were performed successfully in all patients. Closure of the primary entry tear, full expansion of the stent-graft, and eventually, thrombosis of the false lumen was achieved in 5 patients. In 1 patient with a short proximal landing zone, a persisting type Ia endoleak was observed. In all patients with successful primary entry closure, a reduction in aneurysm diameter occurred. Mean follow-up is 16 months (range, 4 to 25). CONCLUSIONS: Endovascular stent-graft placement of aneurysms involving the descending aorta originating from chronic type B dissections may serve as a valuable treatment option in this complex pathology. The chronic dissection membrane can be successfully compressed against large areas of the native aortic wall. A sufficient proximal landing zone is mandatory for early and late success.
