Clinical evaluation of lumbar disc heniation treated by percutaneous lumbar discectomy associated with O_3 injection / 介入放射学杂志

ABSTRACT

Objective To evaluate the value of PLD associated with O 3 injection for the treatment of lumbar disc heniation.Methods Lateral decubitus position on healthy side under the direction of DSA, a working pipe was inserted from the back lateral way to damage the disc contents through multiple angles followed by extirpation of the nucleus pulposus and then injecting O 2-O 3 10 ml into the lumbar disc space and near by area of the inter vertebral foramina. As for patients with L4-5 and L5-S1 protrusions the main lumbar discs can be treated in the same way, but for another minor one, the injection of O 2-O 3 10 ml into the lumbar disc and the nearby intervertebral foramina and ethanol through a 21G needle would be properly promising. Results Puncture and technical opertaion were performed successfully in all the patients with excellent results in 63, good in 27, and poor in 10. 120 cases with injection of O 2-O 3 into the lumbar discs showed the figure of lumbar space displaying clear in 37 cases, less clear in 35 cases, only gas entering lumbar disc at the needling point with lumbar space displaying unclear in 30 cases and lots of gas entering the front space of canalis vertebralis cavitas epiduralis in 18 cases. Conclusions PLD associated with O 3 injection is the advantageous supplement mutually posscessing safety and efficancy.
