Leg malperfusion caused by dynamic obstruction is a serious complication of aortic dissection. 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-year-old 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.
动态阻塞导致的下肢灌注不良是主动脉夹层的严重并发症。由于下肢灌注不良主要基于间歇性跛行和行走时麻木等非特异性症状进行诊断，因此其诊断较为困难。在本研究中，我们报告了一例51岁男性慢性主动脉夹层合并下肢灌注不良的病例，该病例通过多普勒超声得以诊断。行走后出现双峰和衰减的速度波形变化可能会使我们怀疑存在动态阻塞导致的下肢灌注不良。
