Venography

An important and sometimes essential diagnostic method for determination of permeability of deep veins and their functional ability is phlebography. At present, there are over 100 methods contrasting studies veins but they are not yet fully meet the needs of the clinic, and the search for better ways continues.
Stop at each method venography is not possible, they are described in separate manuals. Moreover, an attempt to combine the known methods flebografii in the same classification of causes difficulties associated with many options and technical execution. So maybe the contrast of the entire vein (total, selective) or part of it, and in various provisions of the limb (vertical, horizontal, inclined), the delay of venous blood circulation or its performance, at a certain frequency pictures (simultaneous, serial, cinematographic), quantities and concentrations of fluids and so on, in Addition, depending on a place of introduction of a contrast agent distinguish phlebography intravenous, intraarterial, intraosseous, and depending on a way of introduction - the rising (back Vienna feet, back tibia) and downward (transcutaneous puncture femoral vein).
R. P. Askerkhanov (1969) was one of the first proposed a classification of methods and options venography and made a significant scientific contribution to the development of intraosseous and its other methods. Comparative evaluation of modern methods venography and their classification is well described by M. I. Kuzin and co-authors (1971).

In recent years began to be applied more perfect a technique of research - intravenous contrast fluroscopy with selective phlebography. It allows to judge about the degree of filling of the veins, the width of the clearance, off-road, circuits, makes it possible to establish the number and localization of communication veins, function, their valves (C. I. Savitsky, 1971). This method does not require special equipment and can be performed in any medical institution, where there is an x-ray machine.
Application krupnokadrovaya of photofluorograph allows to reduce radiation exposure to the patient, and the doctor when performing venography and allows for 60-70 seconds to make 8-9 pictures (N. Century Vodianitskaia, Yu. I. Raskin, 1968)Is.
I. P. Dauderi (1971) proposed electroretinography method venography. If it instead of x-ray films are used selenium plates from which the image can be transferred within 2 minutes on ordinary writing paper with electrophotographic apparatus. It uses the weaker concentrations of contrast media that are less annoyed intima venous wall, and reduce the number of complications in the form of phlebothrombosis, etc. Touching complications when venography, it should be noted that all iodine-containing contrast substances are destructive for the endothelium veins unlike endothelium arteries, therefore, to resort to it only in cases, when the functional methods of research does not give the right answer.
Important operating phlebography as a method of topical diagnostics and status checks main veins after thrombectomy, regional perfusion, reconstructive and other plastic surgery (E. P. done, E. G. Yablokov, M. I. Filimonov, 1969).
