We herein report a case of leg malperfusion caused by dynamic
obstruction after aortic dissection diagnosed by the exercise ankle
brachial pressure index test that could not be diagnosed solely by
examining the symptoms and investigations at rest. This case suggests
that exercise can be a key factor in the diagnosis of this complication.
Furthermore, blood pressure elevation can be an exacerbating factor in
dynamic obstruction. We recommend conducting an aggressive evaluation of
the symptoms and medical examinations not only at rest but also under
stress.
