Intra-osseous phlebography and the measurement of intramedullary pressure (IMP) have been used clinically and in experimental animals as qualitative methods of measuring blood flow in the bone. The normal phlebographic appearances in long bones are not clearly understood and the correlation between these appearances and the IMP is not known. The distal femora of 10 anaesthetised rabbits were ca...

At one time, direct intravascular contrast angiography was the standard method for confirmatory diagnosis of venous or pulmonary arterial thromboembolism. Although sensitive and specific, conventional catheter-based contrast imaging is invasive and associated with a risk of phlebitis and thrombosis. These procedures require specialized training and experience in catheter manipulation, as well a...

The characteristics of lymphedema on radionuclide lymphoscintigraphy were studied, and the diagnostic value of radionuclide lymphoscintigraphy in lymphedema was evaluated. In this report radionuclide lymphoscintigraphy was performed in 110 cases of clinically suspected lymphedema. A retrospective study method was used to analyze the imaging results. The typical pattern of lymphedema on radionuc...

From September 1962 to May 1972 145 patients with acute or subacute deep vein thrombosis confirmed by phlebography were treated with streptokinase. During the same period 42 patients considered unfit for thrombolytic therapy were treated with herapin and oral anticoagulants. The results, assessed by repeat phlebography, in 93 of the patients treated with streptokinase were compared with those i...

In the articles below three contributors discuss recent progress in the diagnosis and medical and surgical management of deep vein thrombosis. Mr. Norman Browse concludes that not only is phlebography the most valuable method for diagnosis but that it may help correct management. Dr. P. T. ilute emphasizes that anticoagulants may be ineffective in preventing pulmonary embolism from recent throm...

naturally occurring radionuclide of terrestrial origin (also called primordial radionuclide) are present in various degrees in all media in the environment, including the human body itself. their concentrations in environment decrease continually by decaying. the main objective of this study is to evaluate the radioactivity levels and health risks due to terrestrial radionuclide in soil of yal...

Patients with severe degenerative osteoarthritis of the hip and knee have impaired venous drainage from the juxtachondral cancellous bone across the cortex (M#{233}riel et a!. 1955; Phillips 1966; Arlet, Ficat and Sebbag 1 968; Arnoldi, Linderholm and MUssbichler 1 972). Intra-osseous phlebography will demonstrate the absence of the normal drainage pattern, with delayed emptying of the contrast...
