Use of the variable-length intraluminal sutureless graft.

From August 1987 to May 1988 we treated 4 patients with acute ascending aortic dissections with a variable-length intraluminal aortic prosthesis. This operation uses profound hypothermic circulatory arrest and represents a refinement of existing techniques. There was no mortality, and morbidity was minimal. Modifications of this technique can be used in performing proximal aortic root reconstruction with a composite valved conduit. The use of a variable-length intraluminal prosthesis and hypothermic circulatory arrest is illustrated. This is a safe and useful technique in select cases of acute ascending aortic dissection.
