Lumbar disc herniation is a common and frequent disease that seriously affects the work and quality of life of some patients. The pathological mechanism of sciatica caused by lumbar disc herniation is mainly due to the compression of nerve roots by its herniation and microcirculatory changes, as well as nerve root inflammatory response and neuroimmune factors. The clinical manifestations of the disease are low back pain with/ or lower limb pain and numbness, and in severe cases, walking weakness or even light paralysis. And there are countless treatment methods and therapeutic drugs for lumbar disc herniation, reaching a confusing level, but the prolonged treatment and recurrent attacks still plague many patients with lumbar disc herniation, and one of the big reasons is the failure to achieve typological diagnosis and corresponding treatment. Physicians must master the staging of lumbar disc herniation so that they can better determine whether a patient needs conservative treatment, minimally invasive interventional surgery or open surgery. Lumbar disc herniation should be treated by typing Traditionally, lumbar disc herniation can be divided into four types: bulging disc, herniated disc, prolapsed disc, and free disc. We divide them into two types: contained and non-contained. In contrast, lumbar disc herniation depends on the herniation subtype and the relationship of the herniation to the nerve root. MR images of lumbar disc herniation in asymptomatic people are common, and conservative treatment of contained lumbar disc herniation can achieve better therapeutic results; while the latter two types of disc prolapse and disc free, i.e., non-contained lumbar disc herniation, in which the role of the herniation on the nerve root compression and microcirculatory changes is not unique, the nerve root inflammatory response, neuroimmune factors play a more important role, and the symptoms are more severe and We use CT guidance as the first choice for the treatment of non-contained lumbar disc herniation, because conservative treatment is not effective, and surgery is often used traditionally. CT-guided treatment is more precise The use of collagenase injection for lumbar disc herniation is now a common method of interventional treatment. Usually these interventions are performed under X-ray, and the efficacy is poor because the injection cannot be clear and accurate. Combining domestic and international treatment experience, we designed CT-guided injection of collagenase into the herniated disc for minimally invasive treatment. A large number of subsequent cases have shown that CT-guided placement of the needle tip into the herniated disc location is accurate and better able to avoid important structures in the vital spinal canal, improving both safety and treatment outcomes. Combined laser treatment broadens the indications and accelerates the efficacy For patients with more severe lumbar disc prolapse and freeing, treatment by collagenase injection alone would require a longer process. For this reason, laser vaporization of a portion of the herniated disc is performed, resulting in volume reduction and decompression. Subsequent treatment with targeted collagenase injections effectively accelerates the treatment process for patients with severe discs. Traditionally, emergency surgical treatment is often required, but we use CT-guided laser ablation combined with collagenase injection. Minimally invasive interventional treatment using CT guidance is less invasive than open surgery, has faster recovery, fewer complications, lower costs, and a similar mechanism to open surgery for direct removal of herniations. Since the whole procedure of interventional surgery needs to be performed under CT guidance, the attending physician needs to be proficient in the use of CT and knowledge of lumbar disc herniation treatment. The CT department of the Chinese medicine hospital conducted in-depth research on CT-guided interventional treatment of lumbar disc herniation and designed and carried out the first CT-guided injection of collagenase to reach the site of herniation for the treatment of lumbar disc herniation at home and abroad in 1997. In 2002, the results of this technology passed the science and technology achievement appraisal of Guangzhou Science and Technology Bureau, which considered that the scientific achievements reached the advanced level in China and recommended that the scientific and technological research results be published in the “National Science and Technology Achievement Network” and its papers were published in Chinese radiology journals. Nowadays, patients who have received this surgery have introduced their friends and relatives to the CT room of the district Chinese medicine hospital for treatment, believing that this treatment has opened up a new way out for patients with disc herniation with higher safety and more obvious efficacy outside of open surgery, and is the first choice for patients with non-contained lumbar disc herniation. There is nothing to fear when suffering from a lumbar disc herniation It is not uncommon to find a lumbar disc herniation through MR examination in asymptomatic people, while it is rare or uncommon to find a lumbar disc prolapse, nerve root compression and a free lumbar disc. Conservative treatment is often effective for contained lumbar disc herniation, which includes physiotherapy, drugs, and bed rest, etc. Interventional treatment for those who do not respond to conservative treatment is an extension of conservative treatment by indirectly relieving the herniated material that is compressing the nerve. At present, interventional treatment has become one of the important treatment methods for contained lumbar disc herniation. For non-inclusive lumbar disc herniation herniation of nerve root compression and microcirculatory changes are not the only ones that play a role, nerve root inflammatory response, neuroimmune factors play an important role, symptoms are more aggressive, conservative treatment is not effective, surgery is often used traditionally, today we use CT guidance as the first choice for treatment of non-inclusive lumbar disc herniation. The key to successful treatment of lumbar disc herniation is accurate typological diagnosis and timely and appropriate treatment. The doctors in the CT department of Panyu Hospital of Traditional Chinese Medicine have conducted in-depth research on the typing of lumbar disc herniation diagnosis and CT-guided interventional treatment, which simplifies the diagnosis and treatment of complex lumbar disc herniation and makes patients take fewer detours, and the CT-guided treatment of lumbar disc herniation carried out over the years has been recognized and welcomed by many patients.
