Lower-extremity venography: value of femoral-vein compression.

Lower-extremity venography is usually performed with the patient positioned semiupright on a tilting table and with progressive lowering of the patient’s head to visualize the more superior venous structures [1 ]. Because it is often necessary for the patient to remain recumbent, we have successfully used a technique of totally supine venography by using controlled femoral-vein compression with release just before pelvic filming. This technique yields excellent resuIts with use of a minimal amount of contrast material.
