[Static gamma phlebography with Tc 99-marked blood erythrocytes].
Our personal modification of the isotopic gammaphlebography technique involving red blood cells marked with (a 10 mCu dose of) Tc 99 is described. This process involves a further intravenous injection of the isotope, after a previous injection of 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 are obtained, without performing any other invasive examinations of the lower extremities. 80 patients are studied, and their study is completed by means of the Doppler effect and impedance rheopltethismography. The results are discussed: 87,5% and 88,6% of good correlations in Doppler are obtained for acute and chronic cases respectively. 77,75% and 92% with impedance rheoplethismography in the same cases. Six evidencing cases are shown.
