When people have a medical condition, they often look for a way to minimize the cost: effective, safe, economical, and least painful. Non-vascular interventions may achieve this for some patients. If a vertebral compression fracture occurs, you may immediately think of going to surgery for surgical treatment, but do not know that there is now a non-vascular interventional therapy, which will make the patient less traumatic, less costly, and the recovery time is also very short; when someone suffers from tumors or abscesses, you may be in a hurry to choose the surgery, but did not think that non-vascular interventional therapy will be better. Non-vascular interventional therapy has developed rapidly in recent years and is one of the most promising treatments in the 21st century. It is a type of interventional radiotherapy, which means that it is a minimally invasive diagnosis and treatment of diseases by percutaneous puncture under the guidance of CT, X-ray, ultrasound and other imaging equipment, using needles, catheters, stents and other instruments. This method can minimize trauma while obtaining certain curative effects, and is now being accepted by more and more medical experts and patients. Non-vascular interventional therapy technology is widely used, specifically in the following areas: Biopsy It is in the CT and ultrasound-guided access to the lesion area specimens for histological pathology, the accuracy of which is as high as 90% or more. It makes it easy to diagnose many diseases that were previously difficult to diagnose, and it can not only eliminate the trauma brought about by surgical biopsy, but also win the time for patients to treat the disease, and provide the basis for designing a reasonable treatment program. Indications: Solid lesions in various parts of the body, including inflammatory lesions and tumors. Tumor treatment The use of various physical and chemical factors to locally destroy and eliminate tumors. These techniques include: iodine-125 particle implantation for intratumoral irradiation (commonly known as “intracorporeal gamma knife”), radiofrequency ablation of tumors (Fusion Knife), chemoablation of tumors, electrochemotherapy, cryotherapy, thermotherapy, and ultrasound focusing. Indications: solid tumors, such as tumors of the lung, liver, pancreas, prostate, etc., and metastatic tumors of small number. Nerve block Precise blockage of nociceptive afferent nerves under CT guidance to achieve analgesia or pain relief. Indications: intractable pain caused by tumor or other causes, such as visceral neuralgia caused by abdominal malignant tumors. Osteoplasty (Strengthening and stabilization of diseased bone) A special material called “bone cement” is injected into the area of fracture or bone lesion to increase the strength and stability of the lesion. Indications: Vertebral fractures and pain due to osteoporosis, tumors and metastatic tumors. Herniated disc treatment Reduce the internal pressure of intervertebral discs and reduce or eliminate the degree of disc herniation by means of laser ablation, nucleus pulposus aspiration, dissolution and aspiration. Indications: patients with herniated discs without nucleus pulposus consolidation or prolapse. Cavernous drainage Using special instruments to puncture percutaneously to “open the canal and release water” to each obstruction site. Indications: biliary tract, urinary tract obstruction, obstructive hydrocephalus, etc. Drainage of hematoma and abscess Drainage of hematoma and abscess in the body cavity by percutaneous puncture with special instruments. Indications: traumatic, spontaneous, postoperative and other inactive hematomas, abscesses in various parts of the body, especially unicompartmental abscesses. Sclerotherapy of cysts Percutaneous aspiration of cyst contents, followed by injection of “sclerosing agent” to eliminate the secretion function of cyst wall cells, avoiding the risk of cyst rupture, and achieving the purpose of protecting organ function and eliminating symptoms. Indications: Liver and kidney cysts, ovarian cysts and other cysts. Expansion and molding of luminal stenosis Expansion and molding of luminal stenosis by using balloon, or placing stent at the same time to make the stenosis open and relieve obstruction. Indications: bronchial stenosis, esophageal and gastrointestinal stenosis, biliary tract, urethra and fallopian tube stenosis. In conclusion, with the development of newer medical devices, the therapeutic scope of non-vascular interventional techniques is expanding, which will bring benefits to more patients.
