1 INTRODUCTION
The diagnosis of leg malperfusion caused by dynamic obstruction after
aortic dissection is difficult because the dissection flap remains
unstable and often causes changes in symptoms. We herein report a case
of leg malperfusion caused by dynamic obstruction after aortic
dissection diagnosed by the exercise ankle brachial pressure index
(Ex-ABPI) test. We believe that this test is more objective and useful
than the methods used for making a diagnosis in previous
reports.1,2 Furthermore, the present case demonstrated
a unique feature of the relationship between leg malperfusion and blood
pressure (BP).
