Hybrid Endovascular Aorta Repair with Simultaneous Supra-aortic Branch or Iliac Branch Revascularization

摘要

Objective To describe a hybrid endovascular procedure for aorta repair with different kinds of bypass followed by concomitant placement of stent graft in the aorta. Methods From June 2007 to May 2008, 5 consecutive patients who presented with aortic aneurysm or dissection were treated with a new hybrid aorta repair technique. Complete surgical rerouting of supra-aortic vessels was simultaneously created by endovascular repair of aortic arch aneurysm with stent graft. Hybrid left carotid-subclavian bypass with stent graft deployment covering the ostium of the left subclavian artery was performed in a Debakey type III aortic dissection case. The supra-aortic branch was revascularized in 2 cases from ascending aorta to bilateral common carotid arteries using a 16-8 mm bifurcated graft, then total aortic arch and descending artery was occluded with stent-graft. The left carotid artery to the left subclavian artery bypass was created in 1 case, followed by stent-graft deployment. Two cases of infrarenal abdominal aortic aneurysm underwent left external iliac artery to left internal iliac artery bypass by a retroperineal route, then hybrid procedure was performed with bifurcated stent-graft. All stent grafts were deployed via a retrograde femoral artery approach in 5 patients. Results Technical success with complete aneurysmal exclusion was achieved in all patients. There was no incidence of endoleak. During a follow-up period of 2 to 10 months, documented perioperative neurologic events did not occur in all patients. One patient suffered from adult respiratory distress syndrome. After received tracheostomy, he recovered later. There was one death resulting from a postoperative myocardial infarction. Conclusion Hybrid arch repair provides an alternative therapy to patients otherwise considered prohibitively high risk for traditional open arch and thoracoabdominal aorta repair.
