Abstract

|
For last 5 years (1968-1973) lumbar myelography with water soluble contrast medium (Myelotrast or abrodil, sodium-monoiodomethyl sulphonyl ICH, SO, Na) has been performed in 324 patients who were impressed or diagnosed as lumbar disc herniation in Radiological Department of National Medical Center, Seoul, Korea.
The results areas followings.
1) Age and sex distibutions were male 180, female 144 and from 12 to 68 year old. Highest incidence is noted in 30-39 age group (91 cases).
2) In simple film, spondylosis was noted in 96 cases(29.6%). scolisois in 79(24.4%), straightening in 62(19. 1%) and disc space narrowing in 154(48%).
3) The distribution of disc space narrowings (154) in simple film is highest in L,-Ls level (113) and 22 in Ls-S, level, 18 in L3-L, level etc.
4) In lumbar myelography, positive findings in 180 cases (55.5%), non-specific in 124 cases (33.3%) and borderline in 20 cases (6.2 %) .
A) The contents of the positive fingings(180) are single disc herniation in 154 cases multiple disc herniation in 26 cases.
b) The distribution of single disc herniation (154) are 122 cases in L,-Ls level, 23 cases in Ls-S, level etc.
c) In multiple lesions(26), highest incidence in L,-L5-S, level 14 cases and 8 cases in L,-L,-L5 level etc.
5) Surgical operation was performed in 135 cases (41. 6% of all).
6) Comparing myelographic findings with operative findings, false negative(radiologically free but
positive in surgery) in 6 cases (5% of operation case), false positive(radiologically positive but free in
surgery) in 2 cases(1% of surgery case) and 94%(127) was detactable in myeloraphy preoperatively. 7) Advantages of the water soluble contrast medium in lumbar myelography.For last 5 years (1968-1973) lumbar myelography with water soluble contrast medium (Myelotrast or abrodil, sodium-monoiodomethyl sulphonyl ICH, SO, Na) has been performed in 324 patients who were impressed or diagnosed as lumbar disc herniation in Radiological Department of National Medical Center, Seoul, Korea.

a) Completely and quickley resorbed and eXcreted from the body through the urine in d matter of minutes.
b) Mixes completely and homogenusly with spinal fiuid.
c) It can fill out every little corner of the spinal canal.
d) Low incidence of pseudoindentation(1%).
e) It is not so dense that fine spinal nerve to be visible through the contrast.
