A diagnosis of the malperfusion is difficult because it is made mainly on the basis of nonspecific symptoms such as intermittent claudication and numbness on walking. In the present study, we reported on a case of a 51\u2010year\u2010old man with leg malperfusion in chronic aortic dissection diagnosed by Doppler ultrasound. The combination of bisferious and dampened velocity waveform changes after walking may lead us to suspect a leg malperfusion caused by dynamic obstruction.<\/jats:p>","DOI":"10.1111\/echo.14198","type":"journal-article","created":{"date-parts":[[2018,12,1]],"date-time":"2018-12-01T12:45:25Z","timestamp":1543668325000},"page":"189-191","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Doppler
