Interventions are classified according to the route of entry of the device into the lesion: endovascular interventions and non-endovascular interventions. Endovascular intervention refers to the use of a 1-2mm thick puncture needle to enter the human vascular system by puncturing the superficial arteries and veins of the human body, and the doctor, with the knowledge of vascular anatomy, delivers the catheter to the location of the lesion under the guidance of the angiography machine, injects the contrast agent through the catheter to show the vascular condition of the lesion, and treats the lesion in the blood vessel. These include: arterial embolization, angioplasty, etc. Commonly used body surface puncture points are femoral artery, radial artery, subclavian artery, jugular artery, etc. Non-vascular intervention means: simply speaking, without entering the human vascular system, under the monitoring of imaging equipment, directly puncturing through the skin to the lesion, or entering the lesion through the human embodied channel, and treating the lesion. These include: percutaneous puncture tumor biopsy, intratumoral injection, disc puncture decompression, disc puncture ablation and so on. In addition, there are also treatment methods that use puncture needles to directly puncture through the body surface to the artery supplying blood to the lesion. For the time being, they are classified by us as non-vascular interventions.
