[Possibilities of radionuclide study of lower-limb muscles perfusion in diagnosis of chronic arterial insufficiency].

: The authors have hereby proposed a method to diagnose lower-limb muscular ischaemia by means of scintigraphy, used in 35 patients suffering from atherosclerosis obliterans with stage IIB and III A chronic arterial insufficiency of limbs. To do so, administration of the radioactive agent "Myoview" (⁹⁹m)Tc-tetrophosmine) manufactured by the "Nycomed" Company into a patient's peripheral vein was followed by assessing its accumulation in lower-limb muscles at rest and after standard physical load. Alterations in the parameters studied relative to the norm made it possible to judge on the presence of lower-limb circulatory impairments. The method proved highly efficient, thus making it possible to use it for both therapeutic decision-making and probably in future for dynamic control after the treatment performed. Minimally invasive nature and simplicity in use of the methodology open wide possibilities for its use.
