Zusammenfassung

Juxtarenale Aortenaneurysmen stellen eine besondere Herausforderung für den behandelnden Gefäßchirurgen dar. Grund ist die operative Rekonstruktion unter Mitbeteiligung der Nierenarterien. Neben der langjährigen als Goldstandard etablierten offenen Therapie stellen neuere endovaskuläre Techniken, wie die Chimney-Technik („chimney technique with endovascular aneurysm repair“, Ch-EVAR), eine attraktive Alternative dar, die besonders für Hochrisikopatienten geeignet sind. Die Chimney-Technik ist insbesondere dann vorteilhaft, wenn anatomische oder klinische Gegebenheiten eine Behandlung mithilfe der fenestrierten Technik nicht zulassen. Die zunehmende Erfahrung bestätigt ihre komplementäre Rolle von „bailout“ als eine valide Therapieoption von juxtarenalen Aneurysmen.

Chimney technique for juxtarenal aneurysms

Abstract

Juxtarenal aortic aneurysms represent a special challenge for the treating vascular surgeon. The reason is the operative reconstruction with involvement of the renal arteries. Open repair is the gold standard in the treatment of this clinical entity; however, in the case of high risk patients with severe comorbidities, alternative endovascular techniques, such as the chimney technique with endovascular aneurysm repair (Ch-EVAR), represents a promising and viable therapeutic option. The chimney technique is particularly advantageous when anatomical or clinical circumstances exclude treatment with the fenestrated technique. The increasing experience confirms its complementary role as a valid treatment option for juxtarenal aneurysms.
