[Phlebography of the upper extremity: assessment of various x-ray signs].

The article reports on the findings obtained in 56 serial phlebographies of the upper extremity. Using 17 phlebographies without pathological findings as basis, the physiological phenomena of venous contrasting in the region of the shoulder and arm are examined. The remaining phlebograms with pathological findings are assessed according to different criteria, such as localisation and extent of venous vascular occlusion, visualisation of vascular clot and formation of collaterals resulting in collateral circulation.
