Endovascular repair of acute type B aortic dissection: midterm results.

Purpose: To evaluate midterm results of endovascular stent-graft placement for acute Stanford type B dissection (TBD).

Methods: A retrospective review was conducted of 35 consecutive patients who were treated with stent-graft implantation for acute TBD between July 1996 and July 2007. Computed tomographic (CT) volumetric analysis of the true lumen (TL) and false lumen (FL) changes in 23 patients was performed, as well as evaluation of the influence of re-entry points and length of stent-graft coverage on volume changes.
