title: Percutaneous insertion of a jacketed stent to close the entry of dissecting aortic aneurysms of DeBakey types I and II.
abstract: As a treatment for dissecting aortic aneurysms of DeBakey Types I and II, a percutaneous insertion method using a new jacketed stent was developed. The efficacy of the method was evaluated in an animal study. We developed a special stent prepared by modifying the original Gianturco self-expandable metallic stent and a fabric patch. A model of a dissecting aortic aneurysm of DeBakey Type I was created in dogs. The device was inserted into the ascending aorta from the left carotid artery through a sheath-introducer system. The aortogram showed the bloodstream through the false lumen before the insertion, but no bloodstream after the stent insertion. The autopsy showed that the entry, the reentry, and the false lumen were completely filled with fresh thrombus. By using this stent, we successfully achieved an interventional treatment for dissecting aortic aneurysms of DeBakey Types I and II.
