“…It will not therefore detect small calf vein thrombi. Such failure has been reported previously (Evans, 1970, Milne et al, 1971 and was confirmed by our false-positive and falsenegative results. Nine out of 42 limbs thought not to contain thrombi on ultrasoumd screening had small calf vein thrombi, and six out of 24 limbs thought to have thrombi in the popliteal/ calf segment had no thrombi demonstrable on phlebography.…”

“…The Doppler ultrasound technique (Milne et al, 1971) detects only complete occlusions of the major veins and must be regarded as a crude screening test for massive thrombi. Impedance plethysmography shows promise as a useful screening test (Strandness and Sumner, 1972), but even if accurate will only serve to indicate those patients requiring venography.…”

Radionuclide venography for the demonstration of the proximal deep venous system

The majority of pulmonary emboli originate in the deep veins of the lower limb. Fatal emboli usually arise from thrombi that have extended into the femoral or iliac veins or lower inferior vena cava. It is often impossible to demonstrate this area, the proximal venous segment, using conventional ascending venography when there is deep venous occlusion. The alternative methods available--retrograde, pertrochanteric and transfemoral venography--are invasive. Radionuclide venography (RNV) has been developed as a less invasive alternative. It has been found to be accurate in the proximal deep venous system when compared with conventional ascending venography, and in the presence of proximal occlusion it gives images unobtainable by other means. The radiation dose is extremely low and a perfusion lung scan is obtained without further injection of isotope. RNV appears to be the best method for monitoring the progress of thrombolytic therapy for major venous occlusion.

“…Although Milne et al (1971) cast some doubt on the reliability of the doppler technique in detecting deep-vein thrombosis, Sigel et al (1968) found that compared with clinical examination the doppler was correct on phlebography in 83 % of cases when the findings disagreed and in 96 % of cases when they concurred. A similar degree of accuracy is reported by Evans and Cockett (1969) and this technique is being used increasingly to monitor post-operative surgical patients (Mcllroy, 1972;Little and Binns, 1972).…”

SummaryA consecutive, randomly allocated, controlled, doubleblind clinical trial of the prophylactic effect of a single pre-operative low dose of heparin on the incidence opost-operative deep-vein thrombosis showed no reducf tion in the number of thromboses detected.Fifty-five patients were given 5000 units of heparin subcutaneously 1-1k hr pre-operatively and fifty-seven patients were given a placebo. The incidence of thrombosis detected by the doppler ultrasound was 14-5 % in the heparin group and 12-3 % in the control group.It is suggested that a further trial monitored by ultrasound is indicated in which low-dose heparin is given for various periods post-operatively in addition to a pre-operative dose.
