[Static scintigraphy using technetium 99 labelled red blood cells]

Our personal modification to the isotopic gammaphlebography technique involving red blood cells marked with (a 10 mCu dose of) Tc-99 is shown. This process involves further the injection of the isotope endovenously in the inner face of the elbow articulation, after having first injected 2 ml Cl2Sn, which allows re-injection of the radioactive bolus after its passage through the lung region, so that more accurate and complete images may be obtained, without having to perform any manipulations in the lower extremities. 80 patients are studied, and their study is completed by means of the Doppler Effect and impedance rheopletismography. The results are shown : 87,5% and 88,5% of good correlations in Doppler are obtained for acute and chronic cases respectively. 77,75% and 92% with impedance rheopletismography in the same cases. Six evidencing cases are shown.
