COMPLETE REPAIR OF DEBAKEY III-B TYPE DISSECTING ANEURYSM

We have experienced five complete repair cases of aortic dissections, four of which classified as DeBakey type III-b and one done as the type III-b like abdominal dissection were treated with entry and re-entry at the same time or in two-step procedure. Case 1 and 3 with major viseral branch from true lumen underwent graft replacement of decending aorta and clossure of re-entry. Case 2 with visceral branch from false lumen underwent graft replacement of decending aorta and abdominal aorta. Case 4 with abdominal dissection underwent clossure of entry and re-entry. Case 5 with aneurysmal change of the aortic dissected lesion underwent all replacement of dissecting aorta and reconstraction of visceral branch. Their postoperative courses are uneventful without complications such as paralysis and visceral ischemia, and DSA have demonstrated favarable results. We believe these methods are currently radical operations for type III-b dissection.
