[Comparative evaluation of saccoradiculography and lumbar phlebography in the diagnosis of lumbar disk herniation].

A comparative evaluation of two relevant methods (saccoradiculography and lumbar epidural venography), based on 246 case studies (133 of which surgically treated), did not reveal that one of the two could be adopted as elective test with regard to its diagnostic accuracy. However if we consider tolerance and complications of each method, lumbar epidural venography appears to be the elective test in herniated lumbar disk diagnosing.
