| Popis: | In patients with multilevel arterial obstructive disease, assessment of the severity and location of the pathology is a difficult diagnostic problem. As reported recently, the intra-arterial pressure in the common femoral artery may become normal, although aorto-iliac obstructive disease is present if the superficial femoral artery is occluded. Aorto-iliac obstructive disease can also be assessed by analysis of Doppler spectra obtained from the common femoral artery. In this study, we evaluate if this assessment of aorto-iliac obstructive disease is also harmfully affected by an occlusion in the superficial femoral artery. The results of this study demonstrate that some Doppler parameters (such as acceleration time, slope of the acceleration phase, and the resistance index), which are essential for the assessment of aorto-iliac obstructive disease, are not significantly affected by an occlusion in the superficial femoral artery. Moreover, the study shows that the status of the superficial femoral artery may also be assessed by analysis of Doppler spectra obtained from the common femoral artery. |
