| Abstract: | Arterial insufficiency is recognized in amputee segments of thighs by bioelectrical impedance indices of blood flow. The radiofrequency method of volume detection is painless, noninvasive, and reproducible for diagnostic or therapeutic management of circulatory impairments. It interprets complex changes in electrical conductances in real volumetric terms which are easily understood by physicians.Blood flow indices based on bioelectric impedance in the present study indicate a statistically significant circulatory deficit is present in the amputated thigh of traumatic and nontraumatic amputees. Vascular and degenerative diseases are almost invariably present in the nontraumatic amputee group. |
