[CT-phlebography. A new method for the diagnosis of venous thrombosis of the upper and lower extremities].
Spiral CT venography is a new method in vascular imaging, which is an accurate tool for the evaluation of deep venous thrombosis in the evaluation of deep venous thrombosis in the lower and upper extremity.


METHODS
102 lower extremities and 12 upper extremities were evaluated for deep vein thrombosis using spiral-CT-venography. The results were compared with findings of ascending venography, color coded duplex sonography and clinical follow up.


RESULTS
Spiral CT venography of the lower extremity showed a sensitivity of 100% and a specifity of 96%. The quality of venous opacification with CT venography compared with ascending venography was superior in all venous segments.


CONCLUSIONS
Spiral CT venography is a valuable tool for the detection of deep venous thrombosis. Advantages of the method are the reduction of the amount of contrast material necessary for opacification and the detection of perivascular soft tissue alterations. The application of CT venography is limited due to higher costs and radiation dosage.
