[Ultrasonics diagnosis of venous thrombosis]

Ultrasound phlebosonometry was employed in the examination of 54 subjects with phlebosonometric acute or recurrent in 20, chronic in 34 cases. The results of one or more phlebosonometric examinations were compared with the phlebograms. It was found that ultrasound investigation was reliable more for high (91%) than for low (65%) lesions and for acute (85%) as opposed to chronic (70%) thrombosis. The method is seen as of great importance in cases of phlebothrombosis, especially in acute femoroiliac forms. Even though it is a qualitative examination, and hence cannot take the place of angiography, it can nevertheless limit the use of the latter in cases where it could be dangerous.
