Myeolgraphy is widely used for raiological dianosis of herniated lumbar disc. But the diagnostic accuracy is only about 84% range of 67 to 100% with many cases to false negative and equivocal cases. In cases of extreme lateral disc herniation and short cul de sac or wide epidural space, even quite a large disc herniation cannot be detected on myelography. But with epidural venography these defects of myelograhy can easily be over come. 52 cases of epidural venography were performed in department of Raiology of Capital Armed Forces General Hospitla during the 20 months form May 1979 to December 1980. And the finding were compared with those of myelography and operative results. The results are as follows ; 1. Of 52 cases, satisfactory opacification was obtained in 48 cases(92.3%). 2. Single vein injection was adequate for satisfactory opacification in 40 cases(76.9%). 3. There were 2 cases of retroperitoneal extravasation of contrast media, but the patient recovered without dif iculty. 4. Of 24 cases operated , the venographic findings was confirmed in 21 cases (87.5%) and of the 48 cases adequately opacified, there were only 3 cases of confirmed diagnostic error and so the error rate is only 6.25%. 5. Abnormal findings of myelogrpahy were exactly reproduced on epidural venography and many cases with equivocal or normal myelogrpahic finding were accurately diagnosed with epidural venography. 6. In cases of total block , epidural venography was very useful for evaluation of the caudal portion. So lumbar epidural venography is very useful not only as an adjunctive method to myelography, but also as the first diagnostic procedure for herniated disc , for the procedure is simple and the diagnostic accuracy is very high.
