A novel physician-assembled endograft for the repair of pararenal, paravisceral, Crawford type IV thoracoabdominal aortic aneurysms, and aneurysms requiring treatment after prior repair

Abstract

The early and midterm results with the use of the UM suggest it could be a viable option for the repair of Crawford type IV, pararenal, paravisceral, juxtarenal, and short-neck infrarenal aneurysms (<10 mm) without exposing patients to the increased risk of permanent spinal cord ischemia, renal failure, visceral vessel ischemia, or aneurysm-related mortality that results from open thoracoabdominal aortic aneurysm repair. The high technical success rate, in native and previous repairs, supports the utility of this device as a bail-out technique for failed endovascular aneurysm repair or proximal extension of disease after previous aortic repair. However, experience is limited, and this approach requires further study before widespread adoption.
