Fenestrated stent-graft facilitates emergency endovascular therapy for blunt aortic injury.


BACKGROUND Endovascular stent-grafting with intentional coverage of the left subclavian artery may be used to treat aortic isthmus injury, but this procedure may have serious neurologic sequelae and may not provide an adequate proximal landing zone. In 2005, in an effort to mitigate these problems, we began to use fenestrated stent-grafts for emergency repair of blunt aortic injury (BAI). METHODS Between 2005 and 2007, all patients in our practice with a BAI with mediastinal hematoma (except young patients without an associated critical injury) were treated with immediate endovascular stent-grafting, if anatomically possible. A fenestrated stent-graft was placed from the aortic arch, if the BAI was less than 20-mm distal of the left subclavian artery. The records of the 13 patients in the series were reviewed retrospectively. RESULTS The BAI treatment was successful in all 13 patients. Eight patients (61.5%) were given a fenestrated stent-graft, placed distal to either the ascending aorta (n = 2), brachio-cephalic artery (n = 4), or left common carotid artery (n = 2), without concomitant bypass grafting or transposition of the head vessels. Two patients died of an associated critical brain injury (hospital mortality rate, 15.4%). There were no perioperative complications related to stent-graft usage and no unintentional occlusions of the head vessels by a fenestrated device. One patient underwent open repair of a newly developed type Ia endoleak 7 months after placement of a nonfenestrated stent-graft. CONCLUSION Fenestrated stent-grafts can be used to treat BAI, without any concomitant procedures to provide an adequate proximal landing zone.
