Commentary: multiple chimney grafts for total endovascular revascularization of the visceral arteries in the setting of ruptured TAAA: inventive but let's wait for the smoke to clear on this one.

摘要

Endovascular repair of thoracic and abdominal aortic aneurysms is safe, durable, and effective but only when there is adequate sealing and fixation at the attachment sites. The introduction of fenestrated and branched stent-grafts has made it possible to perform endovascular aneurysm repair (EVAR) when the presence of an aortic arch or visceral artery branches do not have an adequate proximal or distal sealing zone. However, both fenestrated and branched stent-grafts are expensive, time-consuming to manufacture, and unavailable for routine use in the US.
