Computed tomography fındıngs of the epıdural spread of contrast medıa

Abstract

The spread of analgesic and local anesthetics in the epidural space was demonstrated in 13 patients by computed tomography examinations performed after lumbar epidural injection of radiographic contrast material via a percutaneous catheter. TTie volume of contrast material was equal to the volume of analgesic.As a result, the upper level of contrast material was found at upper thoracic segments (T4 and above) in 6 of 13 patients (46%). middle thoracic segments (between T5 and T8) in 4 of 13 patients (31 % ) and lower- thoracic segments (between T8 and Tl2) in 3 of 13 patients (23%).
