Outcome of Stanford type B acute aortic dissection.

Abstract

In acute-phase cases, surgical mortality is so high that medical treatment is preferable unless there are major complications. However, even in patients who had undergone successful initial medical treatment, expansion of the aneurysm, requiring surgery, often occurred. If careful observation reveals any sign of expansion, because elective surgery can be performed at low risk, it should be considered as soon as possible before a rupture develops.
