Isotope venography

Abstract

Abstract An isotope method of venography using 99mTc as pertechnetate (or MAA technetium) and a gamma camera is described. Initial results are encouraging. Good visualization of the major venous channels in the lower limbs and pelvis can easily be obtained. Venous occlusion and the formation of collaterals, particularly in the pelvis, are well shown. It appears to be possible to infer the presence of deep venous occlusion in the calf when delayed filling is seen through normal popliteal and femoral veins. The procedure is entirely painless and can easily be performed in the out-patients' department. It avoids the pain consequent on injection of the usual radiographic contrast media and the phlebitis which may also follow their injection. It does not afford the same degree of anatomical detail but this is of minor importance if operative intervention is unlikely.
