[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.

[Considerations on the role of the so-called non-invasive investigations: Doppler effect, rheography and labeled fibrinogen testi in acute arterial and venous leg].

The author outlines the first results obtained with Doppler investigation in arterial and venous emergencies. He analyzed thereafter the Kakkar test, through which he can detect acute venous more easily than with Doppler. He insists on the difficulty of detecting through either one of these methods, some cases of thrombosis located in the abdominal veins.

[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.

[Study of arterial diseases of the lower limbs using an exercise test monitored by Doppler effect ultrasonometry].

A study has been carried out using Doppler ultrasonometry on 223 cases, 191 of them suffering from occlusive or stenosing arterial illnesses and 12 with deep massive venous thrombosis, together with 68 control cases. Systolic tensions in the popliteal, dorsalis pedis and posterior tibialis arteries, both at rest and after a conveniently standardized effort, were studied every five minutes over periods of up to thirty minutes. The results are shown grouping these patients according to their clinical features and giving their different responses to the test. Special emphasis is given to cases of badly compensated recent intermittent claudication, diffused atheromatosis, asymtomatic arterial stenosis, thromboangiitis obliterans, Leriche's syndrome and hypertensive ulcers.
